A new strategy for the surgical treatment of aortic coarctation associated with ventricular septal defect in infants using an absorbable pulmonary artery band. (1/490)

OBJECTIVES: We propose a new strategy using coarctation repair together with a polidioxanone absorbable pulmonary artery banding to limit operative risk and to spare infants with aortic coarctation subsequent operations. BACKGROUND: The alternative for the surgical management of aortic coarctation associated with ventricular septal defect (VSD) is single-stage repair versus coarctation repair with or without banding of the pulmonary artery. METHODS: Eleven infants (mean weight 2,560 +/- 1,750 g, range 1,320 to 3,800 g) underwent a coarctation repair with a polydioxanone banding. Seven had a trabecular and four a perimembranous VSD. The mean size of the VSD was 5 +/- 0.7 mm (range 4 to 7 mm). The systolic pulmonary pressure was >80% of the aortic pressure in all. The pulmonary band was tightened until the systolic pulmonary pressure fell below 50% of the aortic pressure. RESULTS: There were no hospital deaths. The reabsorption of the banding was complete after 5.7 months in all patients (3 to 6.5 months). The VSD closed completely in four infants and partially in six, in whom the pulmonary artery pressure was normal without evidence for significant left-to-right shunt. One patient with a large trabecular VSD underwent surgical closure of his defect after four months. Finally, a subsequent open-heart surgery could be avoided in 91% (10/11) of patients. CONCLUSIONS: Provided the VSD belongs to types prone to close spontaneously, this policy may reduce the number of surgical procedures per infant as well as in-hospital mortality and morbidity rates. It should be proposed as an alternative to more complex procedures.  (+info)

Rotational acetabular osteotomy using biodegradable internal fixation. (2/490)

We used biodegradable poly-L-lactide screws in rotational acetabular osteotomy in 41 hips of 41 patients, and studied the complications after an average follow-up of 4.9 years (range 1.0-7.7 years). There were 39 females and 2 males, their average age at the time of the operation was 32 years (range 12-55 years). A small subcutaneous abscess appeared around the non-absorbable sutures in 2 patients after surgery. There was 1 case of thrombophlebitis and 1 of local dermatitis. The small subcutaneous abscess resolved after the removal of the suture material in the 2 cases, and the thrombophlebitis resolved with aspirin. The local dermatitis persisted but was cured by local steroid therapy over 5.8 years. The incidence of local dermatitis after the use of biodegradable implants should be further investigated.  (+info)

Inhibition of neointima formation after experimental coronary artery stenting: a new biodegradable stent coating releasing hirudin and the prostacyclin analogue iloprost. (3/490)

BACKGROUND: To minimize acute stent thrombosis and development of restenosis, stents coated with biodegradable and nonbiodegradable polymers have been proposed to serve as sustained-release drug carriers. METHODS AND RESULTS: In both a sheep and a pig model, we examined the vascular response to standard and high-pressure implantation of coronary Palmaz-Schatz stents coated with a 10-microm layer of polylactic acid (MW 30 kDa) releasing recombinant polyethylene glycol (r-PEG)-hirudin and the prostacyclin analogue iloprost, both drugs with antithrombotic and potentially antiproliferative effects. Study observation time was 28 days. Between the corresponding stent groups, no differences were observed with regard to preplacement and postplacement implantation parameters. The morphometric analysis demonstrated that the coating was associated with a greater lumen diameter through a reduction in the mean restenosis area by 22.9% (P<0.02) in the standard-pressure model (sheep) and by 24.8% (P<0.02) in the overstretch pig model compared with uncoated control stents without inducing a local inflammatory response. CONCLUSIONS: The results from this study demonstrate beneficial effects of a polymeric stent coating with polylactic acid releasing r-PEG-hirudin and iloprost on the development of restenosis after coronary stent placement at 4 weeks, independent of the extent of vascular injury. Future studies are proposed to investigate the integration of other substances to further enhance the potential of the stent coating on reducing neointimal formation.  (+info)

In situ tumor vaccination with interleukin-12-encapsulated biodegradable microspheres: induction of tumor regression and potent antitumor immunity. (4/490)

An alternative technology for the local and sustained delivery of cytokines to tumors for cancer immunotherapy was evaluated and shown here to induce tumor regression, suppression of metastasis, and development of systemic antitumor immunity. Treatment of tumor-bearing BALB/c mice with a single intratumoral injection of biodegradable polylactic acid microspheres loaded with recombinant interleukin-12 (IL-12) promoted complete regression of the primary tumor and prevented the metastatic spread to the lung. Mice that experienced tumor regression after being treated rejected a subsequent challenge with live tumor cells, which indicated the development of systemic antitumor immunity. In situ tumor vaccination, ie., injection of IL-12 microspheres into existing tumors, was superior to vaccination of mice with mixtures of tumor cells (live or irradiated) and IL-12 microspheres in inducing systemic antitumor immunity. The sustained release of IL-12 from the microspheres was superior to bolus injection of free IL-12, and intratumoral delivery of microspheres was more effective than other routes of administration. These studies establish the utility of biodegradable polymer microspheres as a clinically feasible alternative to systemic cytokine therapy and cytokine gene-modified cell vaccines for the treatment of neoplastic disease.  (+info)

Soluble biodegradable polymer-based cytokine gene delivery for cancer treatment. (5/490)

Transgene expression and tumor regression after direct injection of plasmid DNA encoding cytokine genes, such as mIL-12 and mIFN-gamma, remain very low. The objective of this study is to develop nontoxic biodegradable polymer-based cytokine gene delivery systems, which should enhance mIL-12 expression, increasing the likelihood of complete tumor elimination. We synthesized poly[alpha-(4-aminobutyl)-l-glycolic acid] (PAGA), a biodegradable nontoxic polymer, by melting condensation. Plasmids used in this study encoded luciferase (pLuc) and murine interleukin-12 (pmIL-12) genes. PAGA/plasmid complexes were prepared at different (+/-) charge ratios and characterized in terms of particle size, zeta potential, osmolality, surface morphology, and cytotoxicity. Polyplexes prepared by complexing PAGA with pmIL-12 as well as pLuc were used for transfection into cultured CT-26 colon adenocarcinoma cells as well as into CT-26 tumor-bearing BALB/c mice. The in vitro and in vivo transfection efficiency was determined by luciferase assay (for pLuc), enzyme-linked immunosorbent assay (for mIL-12, p70, and p40), and reverse transcriptase-polymerase chain reaction (RT-PCR) (for Luc and mIL-12 p35). PAGA condensed and protected plasmids from nuclease degradation. The mean particle size and zeta potential of the polyplexes prepared in 5% (w/v) glucose at 3:1 (+/-) charge ratio were approximately 100 nm and 20 mV, respectively. The surface characterization of polyplexes as determined by atomic force microscopy showed complete condensation of DNA with an ellipsoidal structure in Z direction. The levels of mIL-12 p40, mIL-12 p70, and mIFN-gamma were significantly higher for PAGA/pmIL-12 complexes compared to that of naked pmIL-12. This is in good agreement with RT-PCR data, which showed significant levels of mIL-12 p35 expression. The PAGA/pmIL-12 complexes did not induce any cytotoxicity in CT-26 cells as evidenced by 3- inverted question mark4, 5-dimethylthiazol-2-yl inverted question mark-2,5-diphenyltetrazolium bromide assay and showed enhanced antitumor activity in vivo compared to naked pmIL-12. PAGA/pmIL-12 complexes are nontoxic and significantly enhance mIL-12 expression at mRNA and protein levels both in vitro and in vivo.  (+info)

Early in vivo experience with tissue-engineered trileaflet heart valves. (6/490)

BACKGROUND: Tissue engineering is a new approach in which techniques are being developed to transplant autologous cells onto biodegradable scaffolds to ultimately form new functional autologous tissue. Workers at our laboratory have focused on tissue engineering of heart valves. The present study was designed to evaluate the implantation of a whole trileaflet tissue-engineered heart valve in the pulmonary position in a lamb model. METHODS AND RESULTS: We constructed a biodegradable and biocompatible trileaflet heart valve scaffold that was fabricated from a porous polyhydroxyalkanoate (pore size 180 to 240 microm; Tepha Inc). Vascular cells were harvested from ovine carotid arteries, expanded in vitro, and seeded onto our heart valve scaffold. With the use of cardiopulmonary bypass, the native pulmonary leaflets were resected, and 2-cm segments of pulmonary artery were replaced by autologous cell-seeded heart valve constructs (n=4). One animal received an acellular valved conduit. No animal received any anticoagulation therapy. Animals were killed at 1, 5, 13, and 17 weeks. Explanted valves were examined histologically with scanning electron microscopy, biochemically, and biomechanically. All animals survived the procedure. The valves showed minimal regurgitation, and valve gradients were <20 mm Hg on echocardiography. The maximum gradient was 10 mm Hg with direct pressures. Macroscopically, the tissue-engineered constructs were covered with tissue, and there was no thrombus formation on any of the specimens. Scanning electron microscopy showed smooth flow surfaces during the follow-up period. Histological examination demonstrated laminated fibrous tissue with predominant glycosaminoglycans as extracellular matrix. 4-Hydroxyproline assays demonstrated an increase in collagen content as a percentage of native pulmonary artery (1 week 45.8%, 17 weeks 116%). DNA assays showed a comparable number of cells in all explanted samples. There was no tissue formation in the acellular control. CONCLUSIONS: Tissue-engineered heart valve scaffolds fabricated from polyhydroxyalkanoates can be used for implantation in the pulmonary position with an appropriate function for 120 days in lambs.  (+info)

Functional living trileaflet heart valves grown in vitro. (7/490)

BACKGROUND: Previous tissue engineering approaches to create heart valves have been limited by the structural immaturity and mechanical properties of the valve constructs. This study used an in vitro pulse duplicator system to provide a biomimetic environment during tissue formation to yield more mature implantable heart valves derived from autologous tissue. METHODS AND RESULTS: Trileaflet heart valves were fabricated from novel bioabsorbable polymers and sequentially seeded with autologous ovine myofibroblasts and endothelial cells. The constructs were grown for 14 days in a pulse duplicator in vitro system under gradually increasing flow and pressure conditions. By use of cardiopulmonary bypass, the native pulmonary leaflets were resected, and the valve constructs were implanted into 6 lambs (weight 19+/-2.8 kg). All animals had uneventful postoperative courses, and the valves were explanted at 1 day and at 4, 6, 8, 16, and 20 weeks. Echocardiography demonstrated mobile functioning leaflets without stenosis, thrombus, or aneurysm up to 20 weeks. Histology (16 and 20 weeks) showed uniform layered cuspal tissue with endothelium. Environmental scanning electron microscopy revealed a confluent smooth valvular surface. Mechanical properties were comparable to those of native tissue at 20 weeks. Complete degradation of the polymers occurred by 8 weeks. Extracellular matrix content (collagen, glycosaminoglycans, and elastin) and DNA content increased to levels of native tissue and higher at 20 weeks. CONCLUSIONS: This study demonstrates in vitro generation of implantable complete living heart valves based on a biomimetic flow culture system. These autologous tissue-engineered valves functioned up to 5 months and resembled normal heart valves in microstructure, mechanical properties, and extracellular matrix formation.  (+info)

Scleral plug of biodegradable polymers containing ganciclovir for experimental cytomegalovirus retinitis. (8/490)

PURPOSE: To evaluate the efficacy of a biodegradable scleral plug containing ganciclovir (GCV) in a rabbit model of human cytomegalovirus (HCMV) retinitis. METHODS: To develop a rabbit model for HCMV retinitis, HCMV solution was injected once into the vitreous cavity of pigmented rabbits. The treated animals were divided into three groups: group A received no treatment, group B was treated once with GCV solution, and group C was treated with a scleral plug containing GCV. Rabbits in group B received an intravitreal injection of GCV solution 1 week after HCMV inoculation. In group C, the scleral plug containing GCV was implanted in the vitreous of the rabbits 1 week after HCMV inoculation. Ophthalmoscopically, vitreoretinal findings in each group were graded from 0+ to 4+ every week for 4 weeks after HCMV injection. RESULTS: Eyes of group A rabbits showed whitish retinal exudates and vitreous opacities 3 days after HCMV inoculation. These materials increased gradually until 3 weeks after HCMV inoculation. Scores for vitreoretinal lesions were significantly lower in eyes of group B rabbits compared with those of group A at 1 week after GCV injection (P < 0.05). However, vitreoretinal inflammation in eyes of group B rabbits increased again thereafter, and no significant difference in inflammation between groups A and B was found 2 weeks after GCV injection. In eyes of group C, scores for vitreoretinal lesions were significantly lower compared with those in both group A and group B at 3 weeks after HCMV inoculation (P < 0.01). CONCLUSIONS: The results demonstrated that sustained release of GCV into the vitreous cavity with biodegradable scleral plugs was effective for the treatment of experimentally induced HCMV retinitis in rabbits.  (+info)

OBJECTIVES: We aim to perform a systematic literature review on all studies reporting the clinical outcomes of the use of bioresorbable scaffolds (BRS) in different settings of coronary artery disease (CAD). BACKGROUND: BRS are designed to provide early support of the vessel wall postangioplasty, deliver antiproliferative agents to prevent excessive hyperplastic healing responses and finally disappear when no longer required. Emerging data have provided evidence of their use in specific clinical scenarios. METHODS: A comprehensive literature search was performed by 2 independent reviewers utilizing MEDLINE, EMBASE, and Cochrane Library databases. The only 2 CE marked BRS: everolimus-eluting Bioresorbable vascular scaffold ABSORB BVS and the myolimus-eluting DESolve Bioresorbable Coronary Scaffold (BCS) System were included. RESULTS: The studies were categorized into: ST elevation myocardial infarction (STEMI), stable CAD, and all-comers group. Thirty-one studies were included; 8 in
TY - GEN. T1 - Tensile and flexural creep behaviour of self-reinforced polypropylene composites prepared by compression and injection molding. AU - Kmetty, Á. AU - Bakonyi, P.. AU - Vas, M. L.. AU - Bárány, T.. PY - 2012. Y1 - 2012. N2 - In this work the creep behavior of self-reinforced polymer composites (SRPC) were investigated. As matrix material olefin based thermoplastic elastomeric (o-TPE), as reinforcement highly oriented polypropylenes were used. The tested self-reinforced composites were prepared by filament winding with subsequent compression molding and injection molding (from new pre-impregnated pre-product material) technique. On the SRPC creep tests were carried out. The tensile and flexural creep tests were performed by universal tensile machine and dynamic mechanical analyzer (DMA) test. The results revealed that the creep behavior of the self-reinforced materials depended on the matrix material and the reinforcement structure. The highest strain was achieved using woven ...
Endosteal fixation of a ligament graft with a bioabsorbable interference screw installed in a retrograde manner in ACL reconstruction. The bioabsorbable interference screw is insert-molded with a length of suture extending from the distal tip of the screw for pulling the interference screw into the joint and into position for retrograde insertion at the top of the tibial tunnel. The interference screw has a cannulation extending partially through the screw from the leading tip. The cannulation is shaped to receive a correspondingly shaped driver. The driver is inserted into the tibial tunnel to engage the screw. By turning the driver, the interference screw is turned into the tibial tunnel in a retrograde manner. Accordingly, interference fixation of the graft near the tibial plateau is provided, thereby eliminating graft abrasion at the tibial plateau tunnel opening.
This review discusses and summarizes the recent developments and advances in the use of biodegradable materials for bone repair purposes. The choice between using degradable and non-degradable devices for orthopedic and maxillofacial applications must be carefully weighed. Traditional biodegradable devices for osteosynthesis have been successful in low or mild load bearing applications. However, continuing research and recent developments in the field of material science has resulted in development of biomaterials with improved strength and mechanical properties. For this purpose, biodegradable materials, including polymers, ceramics and magnesium alloys have attracted much attention for osteologic repair and applications. The next generation of biodegradable materials would benefit from recent knowledge gained regarding cell material interactions, with better control of interfacing between the material and the surrounding bone tissue. The next generations of biodegradable materials for bone repair and
This is the first case in the literature describing the V-stenting technique using ABSORB (Abbott Vascular, Santa Clara, California) bioresorbable everolimus-eluting scaffolds (BVS) for the treatment of a left main coronary artery (LMCA) true bifurcation lesion. A 66-year-old woman presented with symptoms of stable angina. A diagnostic angiogram revealed a significant mid-left anterior descending artery (LAD) lesion. After successful implantation of 2 BVS in the mid-LAD, a control angiogram showed haziness extending from distal LMCA into LAD ostium (Medina 0.1.1), likely representing plaque disruption (Fig. 1-I). Due to the fact that the lesions extended in both the LAD and left circumflex artery, we decided to perform V-stenting. A 3.5 × 12-mm BVS (LMCA-LAD) and a 3.5 × 18-mm BVS (LMCA-left circumflex artery) were simultaneously deployed followed by final kissing-balloon inflation. An excellent final angiographic result was achieved (Fig. 1-III). Post-procedural intravascular ultrasound and ...
Spearheaded by principal investigator Stéphane Cook, MD, University and Hospital Fribourg, Switzerland, the trial sought to assess the efficiency and safety of the Absorb bioresorbable vascular scaffold and its ability to reduce long-term complications such as neoatherosclerosis and very late stent thrombosis. Testing the device against the EES and BES, the trial divided its study population into respective treatment groups (BVS, n=78; EES, n=80; BES, n=80).. Clinical outcomes at nine months showed that the BVS arm experienced nine device-oriented major adverse cardiac events, while the EES and BES arms had 11 and four respectively. Results also showed the BVS arm experienced 21 patient-oriented major adverse cardiac events (all-cause mortality, myocardial infarction, revascularization, target vessel revascularization), while EES and BES had 26 and 15 respectively. Cook and colleagues note that in-segment LLL was slightly but significantly higher in BVS compared to EES/BES, and that a possible ...

TY - JOUR. T1 - Determination of bioceramic filler distribution and porosity of self-reinforced bioabsorbable composites using micro-computed tomography. AU - Niemelä, T.. AU - Aydogan, D. B.. AU - Hannula, M.. AU - Hyttinen, J.. AU - Kellomäki, M.. PY - 2011/5/1. Y1 - 2011/5/1. N2 - A micro-computed tomography (μ-CT) image analysis was used in the micro-structural analysis of self-reinforced bioabsorbable osteoconductive composites. The composites studied were known to have a porous structure, but the total porosity of these composites had not been measured due to lack of interconnected pores. The micro-structure of the composites studied has previously been estimated using scanning electron microscopy (SEM). This yielded a very rough estimation of the micro-structure based only on the surface estimate and thus more precise μ-CT image analyses of the total porosity and volumetric filler distribution were done. The present study was performed on five different composites manufactured with ...
Ultrasonically Assisted Anchoring of Biodegradable Implants for Chevron Osteotomies - Clinical Evaluation of a Novel Fixation Method
The invention provides biodegradable implants for treating sinusitis. The biodegradable implants have a size, shape, density, viscosity, and/or mucoadhesiveness that prevents them from being substantially cleared by the mucociliary lining of the sinuses during the intended treatment period. The biodegradable implants include a sustained release therapeutic, e.g., an antibiotic, a steroidal anti-inflammatory agent, or both. The biodegradable implants may take various forms, such as rods, pellets, beads, strips, or microparticles, and may be delivered into a sinus in various pharmaceutically acceptable carriers.

Self-reinforced poly(ethylene terephthalate) composite laminates were manufactured from fabric using a hot press. Fabric was either allowed to shrink or exposed to stretching during different phases of the manufacturing process. Composite macrostructure, crimp, was investigated and results showed that shrinkage affects fibre crimp more than stretching does. Mechanical tests showed that shrinkage do not significantly affect mechanical properties while stretching fabric by 10% during heating results in 50% increase in tensile stiffness. The lack of correlation between crimp and mechanical properties indicates that mechanical properties for self-reinforced poly(ethylene terephthalate) composites are dominated by their microstructure, molecular orientation, which may be affected by the manufacturing process.. ...
BACKGROUND: The Absorb bioresorbable vascular scaffold (BVS) completely resorbs within 3 years after coronary artery implantation. The safety and effectiveness of BVS through this critical 3-year period have not been characterized.. METHODS: We performed an individual-patient-data pooled meta-analysis of the 4 randomized ABSORB trials in which 3389 patients with coronary artery disease were randomly assigned to everolimus-eluting Absorb BVS (n=2164) or cobalt-chromium everolimus-eluting stents (n=1225). The primary efficacy outcome measure was target lesion failure (cardiac mortality, target vessel myocardial infarction, or ischemia-driven target lesion revascularization), and the primary safety outcome measure was device thrombosis.. RESULTS: BVS compared with cobalt-chromium everolimus-eluting stents resulted in higher 3-year rates of target lesion failure (11.7% versus 8.1%; risk ratio [RR], 1.38; 95% confidence interval [CI], 1.10-1.73; P=0.006), driven by greater target vessel myocardial ...
The absence of clinical restenosis in the first major trial of metallic drug-eluting stents (DES) (1) elicited unbridled enthusiasm among interventional cardiologists. However, it did not take long to realize that, although DES were a marked improvement over bare-metal stents (2), they were not perfect. Specifically, McFadden and et al. (3) reported a new complication in 4 patients, late stent thrombosis occurring after discontinuation of dual antiplatelet therapy (DAPT) (3). Since then, we have learned that target lesion-related failures after 1 year (including restenosis as well as thrombosis) occur at a frequency of 2% to 3% per year for all permanent metallic stents, a rate that may continue for 20 years or longer (4,5). The mechanisms contributing to these stent-related failures are multifactorial and include incomplete endothelialization, persistent inflammation, vessel straightening and compliance mismatch, strut fracture, neoatherosclerosis, and others. Bioresorbable vascular scaffolds ...
Background: After the bioresorbable PLLA-based vascular scaffold (Absorb BVS) was taken from the market due to its high adverse event rates, a magnesium-based scaffold (Magmaris) was introduced.Objective: To compare the acute performance of the sirolimus-eluting magnesium alloy Magmaris scaffold with that of the novolimus-eluting PLLA-based DESolve scaffold in terms of appropriate scaffold deployment using optical coherence tomography (OCT).Methods and Results: Data from the final OCT pullback of 98 patients were included (19 Magmaris, 79 DESolve) and analyzed at 1-mm intervals. The following indices were calculated: mean and minimal area, residual area stenosis, incomplete strut apposition, tissue prolapse, eccentricity index, symmetry index, strut fracture, and edge dissection. OCT showed a minimum lumen area for Magmaris vs. DESolve of 6.6 ± 1.6 vs. 6.0 ± 1.9 (p = 0.06). Scaffolds with residual area stenosis |20% were predominantly seen in the DESolve group (15.8 vs. 46.8%; p = 0.01). The mean
This is the first prospective study to evaluate the economic outcomes associated with the use of a bioresorbable scaffold versus a conventional DES among patients undergoing PCI. In this randomized trial involving 2,008 patients with stable and unstable coronary artery disease, we found that the use of the Absorb scaffold was associated with slightly higher procedural costs and index hospitalization costs when compared with the Xience stent. Although the total 1-year costs were also numerically higher in the Absorb group, the cost difference was small (approximately $350/patient) and was not significant. Taken together with clinical outcomes demonstrating statistical noninferiority of the Absorb scaffold to the Xience DES, these findings demonstrate roughly comparable clinical and economic outcomes with these 2 devices within 1 year (assuming a $100 per device price difference).

N2 - Banded spherulite resulting from lamellar twisting due to the imbalanced stresses at opposite fold surfaces can be formed by isothermal crystallization of chiral polylactide and its blends with poly(ethylene glycol) (PEG). Using a polarized light microscope, the handedness of the twisted lamella in banded spherulite is determined. With the same growth axis along the radial direction as evidenced by wide-angle X-ray diffraction (WAXD) for isothermally crystallized samples at different temperatures, the twisted lamellae of chiral polylactides (poly(l-lactide) (PLLA) and poly(d-lactide) (PDLA)) display opposite handedness. The split-type Cotton effect on the C = O stretching motion of ...
Bioresorbable drug-eluting scaffolding appears to be safe and effective in patients with iliac and femoral artery lesions, based on six-month results in the first-in-man ESPRIT trial presented Jan. 22 at the International Symposium on Endovascular Therapy in Miami Beach, Fla.
The DESappear study is an important milestone in the pursuit of bringing innovative therapies with state-of-the-art bioresorbable technologies to treat a vulnerable population of patients with peripheral arterial disease, said Bosiers. I am excited to be working with Akesys Medical with the goal to bring this vital product to the clinic.. DESappear investigator Andrew Holden, director of Interventional Services at Auckland City Hospital and associate professor of Radiology at Auckland University School of Medicine, implanted the first Prava in a 66-year-old patient with 45mm of disease in the mid-superficial femoral artery and 80% blockage.. The diabetic patient with short distance leg claudication demonstrated 0% residual stenosis following the procedure with the Prava scaffold and has recovered well, said Holden. The Prava scaffolds easy deliverability for treatment and its excellent structural support to the vessel without leaving behind a permanent metallic implant has the potential ...
Discover Fantom, REVAs drug-eluting bioresorbable coronary scaffold: a thin strut, x-ray visible BRS made from Tyrocore, a tyrosine-derived polymer.
Novel methods for assessing the electrochemical and micromechanical performance of modular tapers were evaluated, and self-reinforced composite materials were developed for their potential to prevent the onset of mechanically assisted corrosion in modular taper devices. A study of the seating and taper locking mechanics of modular taper samples was conducted, and the effect on taper engagement strength of seating load, loading rate, taper moisture, and taper design/material combination was studied. The load-displacement behavior was captured during seating, and the subsequent pull off load was correlated to seating displacement, seating energy, and seating load. The primary factor affecting taper engagement strength was seating load, and loading rate and design/material factors did not have a significant impact on the quality of the taper engagement. Next, the effect of variation of 7 different design, material, and surgical factors on the fretting corrosion and micromechanical behavior during
Vascular response after coronary angioplasty varies according to the technique. Acute response after balloon angioplasty is characterized by luminal gain in most cases, although dissection can occur during the procedure, putting coronary artery patency at risk. Arterial elastic recoil sometimes follows this acute luminal gain, resulting in some degree of restenosis.. Bare-metal stents represented a great advance because they overcame these 2 main limitations of balloon angioplasty. However, vascular damage created by bare-metal stent implantation can result in intense tissue proliferation around the struts, leading to another form of restenosis: proliferative rather than mechanical recoil. Drug-eluting stents (DES) were developed to overcome this limitation by incorporating antiproliferative drugs. First-generation DES changed the post-stenting healing process; however, the lack of coverage of a substantial amount of DES struts was shown to contribute substantially to stent thrombosis ...

While coronary stents have been used to treat CAD since the 1990s, a new stent technology - the SYNERGY Bioabsorbable Polymer Drug-Eluting Stent System - was approved by the U.S. Food and Drug Administration in October 2015, and is the first and only bioabsorbable polymer stent available in the U.S. Unlike traditional drug coated stents that feature permanent polymer coatings known to cause inflammation within the vessels, the SYNERGY stents coating dissolves and disappears after the stents drug has been released. This action enables quick healing of the blood vessel, leaving only the metal part of the stent in the body; ensuring that the blood vessel remains propped open and can deliver blood to the heart for life.. ...

In medicine, a stent is any device which is inserted into a blood vessel or other internal duct in order to expand the vessel to prevent or alleviate a blockage. Traditionally, such devices are fabricated from metal mesh and remain in the body permanently or until removed through further surgical intervention. A bioresorbable stent, (also called biodegradable, or naturally-dissolving) serves the same purpose, but is manufactured from a material that may dissolve or be absorbed in the body. The use of metal drug-eluting stents presents some potential drawbacks. These include a predisposition to late stent thrombosis, prevention of late vessel adaptive or expansive remodeling, hindrance of surgical revascularization, and impairment of imaging with multislice CT. To overcome some of these potential drawbacks, several companies are pursuing the development of bioresorbable or bioabsorbable stents. Like metal stents, placement of a bioresorbable stent will restore blood flow and support the vessel ...
Drug-eluting stents (DES) have reached a high safety and efficacy profile, becoming the best option for percutaneous coronary interventions (PCI) based revascularization. However, despite their optimal performance, a few concerns remain regarding their use, mainly due to permanent caging of the vessels and its consequences, first of all late stent thrombosis (ST). Bioresorbable scaffolds (BRS) aim to overcome these issues. The results achieved in randomized controlled trials (RCT) by the first generation of poly-L-lactic acid (PLLA) based scaffolds were promising at 1 year, but the first long term reports (albeit flawed by non-optimal implantation technique) have been disappointing, showing, for instance, an increased risk of ST and target vessel myocardial infarction (TV-MI ...

The introduction of drug-eluting stents (DES) in the treatment of coronary artery disease has led to a significant reduction in morbidity. However, the first generation of these devices had no positive impact on the mortality after PCI (compared to bare metal stents), which was greatly attributed to a somewhat increased incidence of late and very late stent thrombosis. Concerns about the role of durable polymers as a potential trigger of inflammation and finally adverse events also led to the development of DES with biodegradable coatings, which leave after degradation of the coating only a bare metal stent in the vessel wall that does not induce an inflammatory response. While such biodegradable polymer DES are increasingly used in clinical practice, there is no data available from head-to-head comparisons between biodegradable and contemporary third generation durable polymer DES ...

A method for the production of a lamellar reflective polymeric body is provided and includes the steps of providing a first stream of a first heat plastified polymeric material and a second stream of a second heat plastified polymeric material, and encapsulating discrete portions of the first polymeric material in the second polymeric material by coextruding the polymeric materials to form a plurality of ribbon-like layers of the first polymeric material within a matrix of the second polymeric material to form the reflective polymeric body. The layers of the first polymeric material are arranged to have their major interfaces aligned substantially parallel to the major surfaces of the body such that at least 30% of light incident on the body is reflected. The ribbon-like layers may be further divided into a series of platelet-like layers to produce layers which are discontinuous in all major planar dimensions by passing the ribbon-like layers through a reciprocating feed plate or valve.
Column 802. five or 10 minutes. It seems absurd that we use the container for those five or 10 minutes but that it will lie in or on the ground for five or 50 years. The third argument relates to disposal. Biodegradable materials are less stable as landfill materials where future buildings may be constructed. That is a short-sighted argument. The fact is that we are desperately short of landfill sites in this country. We cannot go on for ever with that method of disposal. We need to look at alternatives. Primarily, that will be incineration, for which biodegradable materials are well suited. Advances in science now mean that totally biodegradable materials are available, or will soon become available. They are often made of plant material. Paper and cardboard are long established but usually need to be coated with a film to ensure adequate protection of the food. Such a film is usually a plastic, such as polythene, which is not biodegradable. Furthermore, it prevents penetration by water and ...

Last night news began circulating on Twitter that Abbotts Absorb BVS (Bioresorbable Vascular Scaffold) was being withdrawn from the European market. This information was prompted by several physicians posting on Twitter a March 31 Urgent Field Safety Notice/Physician Advisory letter from Abbott addressed to Valued Abbott Vascular Customer.. A number of news sources, including this one, posted articles and tweets to the effect that the Absorb was being taken off the commercial markets and, as the letter stated, Effective May 31, 2017, the device will only be available in clinical register setting at select sites/institutions that will play a pivotal role in the monitoring of this technology until Summer 2018 at which time the situation will be reviewed.. This morning Abbott reacted to this initial flurry of reports that they had pulled the Absorb with some clarification: specifically that the Absorb is NOT being pulled from the market and still retains the CE Mark. An Abbott spokesperson ...
Why are bioresorbable scaffolds so exciting? Simply because they fulfil the task of scaffolding the artery wall during the healing period, and thereafter vanish. In other words, their lifetime is adjusted to the healing process, thus avoiding any risk of causing a new disease (eg, late thrombosis, in-stent restenosis, or neoatherosclerosis) as can happen with permanent stents. Permanent stents do a perfect scaffolding job, but remain in place when they are no longer necessary, leading to a foreign body reaction with complications.
Indias National Pharmaceutical Pricing Authority is slated to revisit its decision to impose price caps on coronary stents in February of 2018 and it is looking for input from manufacturers, the agency said in a statement last week.. The NPPA capped prices for drug-eluting stents and bioresorbable scaffolds in February this year, while also cutting the prices for all coronary stents by as much as 85%. The move was largely criticized by companies within the medical device industry..

A stent is fabricated utilizing a polymer that is selected for its tendency to degrade from the surface inwardly rather than undergo bulk erosion so as to substantially reduce the risk of large particles becoming detached and being swept downstream. Such polymer is hydrophobic yet has water-labile linkages interconnecting the monomers. Ester or imide bonds are incorporated in the polymer to render the surface degrading materials suitable for use in stent applications. The stent may be coated with such polymer or may be wholly formed therefrom.
The hot deformation characteristics of AZ31 magnesium alloy rod extruded at temperatures of 300 °C, 350 °C and 450 °C have been studied in compression. The extruded material had a fiber texture with parallel to the extrusion axis. When extruded at 450 °C, the texture was less intense and the direction moved away from the extrusion axis. The processing maps for the material extruded at 300 °C and 350 °C are qualitatively similar to the material with near-random texture (cast-homogenized) and exhibited three dynamic recrystallization (DRX) domains. In domains #1 and #2, prismatic slip is the dominant process and DRX is controlled by lattice self-diffusion and grain boundary self-diffusion, respectively. In domain #3, pyramidal slip occurs extensively and DRX is controlled by cross-slip on pyramidal slip systems. The material extruded at 450 °C exhibited two domains similar to #1 and #2 above, which moved to higher temperatures, but domain #3 is absent. The results are interpreted in terms of the

The mixture of carrier fluid and pharmacological agent is pressurized for a time sufficient to cause the polymeric material of the intraluminal prosthesis to swell such that the carrier fluid and pharmacological agent at least partially penetrate the swollen polymeric material. Pressure is then removed such that the carrier fluid diffuses out of the swollen polymeric material and such that a predetermined amount of the pharmacological agent remains elutably trapped within the polymeric material.
Contemporary reports by Polish authors on the application of mass spectrometric methods for the elucidation of the subtle molecular structure of biodegradable polymers and their degradation products will be presented. Special emphasis will be given to natural aliphatic (co)polyesters (PHA) and their synthetic analogues, formed through anionic ring-opening polymerization (ROP) of b-substituted b-lactones. Moreover, the application of MS techniques for the evaluation of the structure of biodegradable polymers obtained in ionic and coordination polymerization of cyclic ethers and esters as well as products of step-growth polymerization, in which bifunctional or multifunctional monomers react to form oligomers and eventually long chain polymers, will be discussed. Furthermore, the application of modern MS techniques for the assessment of polymer degradation products, frequently bearing characteristic end groups that can be revealed and differentiated by MS, will be discussed within the context of ...
