The use of drug-eluting stents (DES) has led to a drastic reduction of restenosis rates compared to bare metal stents (BMS), but 5% to 10% of patients receiving DES are still in need of revascularization of the treated vessel. Two important families of drugs are used for stent coating: paclitaxel belonging to the taxane family, and the limus-family such as sirolimus, everolimus, zotarolimus, biolimus A9 and pimecrolimus.. Data regarding the optimal treatment of in-DES-restenosis is very limited. Implanting a new DES for in-DES-restenosis has been reported to be associated with re-restenosis rates as high as 43%. Several recent well published studies have shown a substantial reduction of restenosis using paclitaxel-eluting balloons (PEB) for de-novo lesions and BMS-restenotic lesions.. The objective of this randomized trial is to assess the hypothesis, that PEB are non-inferior to paclitaxel-eluting-stents (PES) for restenosis in limus-eluting-stents (LES), and both, PEB and PES, are superior ...

Clinical and Doppler ultrasound follow-up was performed at 1 and 6 months and shows no related complications and no signs of ISR (PSV=128cm/s).. Discussion. The occurrence of in-stent restenosis (ISR) after carotid artery stenting (CAS) ranges from 3% to 20% and varies with patient risk factors, lesion characteristics, and the location of the stent(s).2,5-7 However, the relatively wide range of ISR rates reported in previous studies may be the result of different definitions/diagnostic testing for ISR, patient selection bias, and length of follow-up.5. DUS is often used to monitor the patency of the stent and the occurrence of ISR. For routine evaluation of unstented carotid arteries, DUS is a well validated diagnostic test and the cut-off criteria for the different degrees of stenosis are clear.8,9 The peak systolic velocity (PSV) is the best predictor for the severity of the stenosis.10 However, the degree of restenosis in a stented carotid artery, measured according to the North American ...

Multiple randomized clinical trials and pooled analyses have shown improved clinical outcomes of primary PCI when compared with fibrinolytic therapy. Primary PCI for STEMI results in greater patency of the infarct-related artery (IRA) and lower rates of death, re-infarction, and stroke when compared with fibrinolysis. The use of coronary stents has reduced the need for repeat revascularization in patients treated with primary PCI. However, in the setting of STEMI this reduction in target lesion revascularization (TLR) did not reduce re-infarction rates or both short term and long-term mortality rates. This was confirmed by a large meta-analysis by De Luca et al, using 13 randomized trials and involving 6922 patients. In studies evaluating DES versus BMS in STEMI mortality rates are similar in patients treated with BMS or DES. Although TLR rates are reduced with the use of DES, there have been concerns about long-term delay of arterial healing produced by both the Cypher DES and Taxus DES and the ...

The invention is essentially characterized in that in a first step a substrate is provided, which is coated with defined pattern of protrusions of a coating layer of a different material, so that an interface is defined between the substrate and the coating layer. As an example, the patterned coating layer can be applied by first forming an essentially homogeneous coating layer, which is then partially removed by means of photolithographic and etching techniques, leaving nanometer sized protrusions in that layer. As a next step, the surface provided with these structures is modified by selectively removing protrusions by means of a micro-device. Such a micro-device can be formed in a similar way to a scanning probe microscope (SPM) tip. The presence or absence of a protrusion represents a readable data bit information.

A method of characterization of a coating on a surface such as a paint coating having metallic flakes distributed within such coating. Single and multi-angle models are utilized. The coating is characterized by measurements having components of light reflected by the metal flakes and attenuated on its exit route from the coating, of light scattered in the entering path of the beam as it travels through the coating, of light scattered by the reflected beam on its exit from the coating, of light scattered in the entering path then reflected by the metallic flakes and attenuated in the coating on exiting, and of light scattering in the exit path, both to the metallic flake and reflected by the flake and attenuated on its exit from the coating. Methods of color matching a coating having a metallic flake distribution within the coating are included using reflectance factors and tristimulus values and minimizing the sum of the squares of the deviation between samples.

It would absolutely work!. The aluminium wire would have to be wrapped around, or sitting on top of, something made from tungsten or molybdenum because aluminium will definitely melt. Unfortunately the chamber, aluminium wire and plastic part would have to be super clean or the film will come out golden brown (Ive seen this happen). The dirtiest part of the film is the first part to be deposited, so the quality of the film will still need to be decent even to just view through the plastic. I helped someone make disposable electrodes for a plasma physics experiment by coating an acrylic disc with aluminium; theyd then blow it off will a few megavolts to study the plasma it made, then wed re-coat it. It worked like a charm.. Youd need more than just a rotary vacuum pump though: you could use a titanium evaporation in another part of the chamber to increase the vacuum :). You could also try using some gallium to coat the plastic part, that should leave a nice shiny plastic-metal interface ...

CERAMIC COATINGS ARE AN ALTERNATIVE TO organic or polymer based coatings for selected surface coating applications. When protecting a surface, it is usually less expensive to use organic coatings rather than other materials such as ceramic coatings. However, organic paints have limitations and will not meet all service requirements. Though more expensive, for some applications ceramic coatings may be a more suitable form of protection. Vitreous (glassy) ceramic coatings are chosen for application over a substrate for one or more of several reasons [1]. These reasons for selecting a ceramic coating in preference to an organic paint include rendering the surface more chemically inert, impervious to liquids and gases, more readily cleanable, and more resistant to service temperature, abrasion, and scratching. The chemical durability of ceramic coatings in service substantially exceeds that of organic paints [2]. Vitreous coatings are formulated to be resistant to a variety of reagents, from acids ...

Thick opaque ceramic coatings are used to protect delicate microelectronic devices against excited energy sources, radiation, light, abrasion, and wet etching techniques. The thick opaque ceramic coating are prepared from a mixture containing phosphoric anhydride, i.e., phosphorous pentoxide (P2 O5), and a pre-ceramic silicon-containing material. It is preferred to also include tungsten carbide (WC) and tungsten metal (W) in the coating mixture. The coating is pyrolyzed to form a ceramic SiO2 containing coating. A second coating of plasma enhanced chemical vapor deposited (PECVD) silicon carbide (SiC), diamond, or silicon nitride (Si3 N4), can be applied over the thick opaque ceramic coating to provide hermeticity. These coatings are useful on patterned wafers, electronic devices, and electronic substrates. The thick opaque ceramic coating is unique because it is resistant to etching using wet chemicals, i.e., acids such as H3 PO4 and H2 SO4, or bases.

The clinical success of a bone-anchored implant is controlled by many factors such as implant shape, chemical composition, mechanical and surface properties. The surface properties (e.g. charge, wettability and roughness) are considered to be important parameters for the biological acceptance of the biomaterial, whereas the bulk properties control the biomechanical behaviour. For implants designed to be used in load-bearing applications in the skeletal system, the biomaterial should preferably integrate into bone tissue for a long lasting function. Lack of integration between the implant and bone increases the risk of micromotions, infections, soft tissue encapsulation, which all reduces the survival rate of the implant and makes revision surgery necessary. Coatings and surface modifications can be used to tailor properties of implant surfaces, and further improve the potential bone bonding and bone in-growth, compared to unmodified surfaces. A biomimetic method, developed by Kokubo, can be used ...

Drug-coated/drug-eluting balloons (DCB/DEB) have been shown to be very effective in treatment of patients with DES-ISR [4]. According to a single-center, randomized study, DCB showed better clinical and angiographic results in treatment of DES-ISR in comparison to BA [9]. The PEPCAD-DES study, a prospective, multicenter, randomized trial of 110 randomly assigned patients, comparing the impact of paclitaxel-coated balloon angioplasty for treatment of DES-ISR versus conventional BA showed that paclitaxel-coated balloon angioplasty was superior to BA alone for treatment of DES-ISR [10]. In addition, ISAR-DESIRE 3 study, a prospective, randomized, multicenter clinical trial including 402 patients with limus-DES-ISR comparatively investigated the efficacy of paclitaxel-eluting balloon versus paclitaxel-eluting stent versus BA alone and confirmed that DCB/DEB was non-inferior to PES and that both DCB/DEB and PES were superior to BA alone in treatment of DES-ISR [11]. Available data from these ...

Bacterial infection from medical devices is a major problem and accounts for an increasing number of deaths as well as high medical costs. Many different strategies have been developed to decrease the incidence of medical device related infection. One way to prevent infection is by modifying the surface of the devices in such a way that no bacterial adhesion can occur. This requires modification of the complete surface with, mostly, hydrophilic polymeric surface coatings. These materials are designed to be non-fouling, meaning that protein adsorption and subsequent microbial adhesion are minimized. Incorporation of antimicrobial agents in the bulk material or as a surface coating has been considered a viable alternative for systemic application of antibiotics. However, the manifestation of more and more multi-drug resistant bacterial strains restrains the use of antibiotics in a preventive strategy. The application of silver nanoparticles on the surface of medical devices has been used to prevent

Medical devices implanted in the body or in contact with flowing blood faces two critical challenges that can threaten the life of the patient the device is meant to help - blood clotting and bacterial infection. Researchers from the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a new surface coating for medical devices using FDA-approved materials. The super-repellent coating can be adhered to existing, approved medical devices. In a two??step surface??coating process, the researchers chemically attached a monolayer of perfluorocarbon, which is similar to Teflon. Then they added a layer of liquid perfluorocarbon, which is widely used in medicine for applications such as eye surgery. The team calls the tethered perfluorocarbon plus the liquid layer a Tethered??Liquid Perfluorocarbon surface, or TLP for short. The coating successfully repelled blood from more than 20 medically relevant substrates the team tested - made of plastic to glass and metal - and

A stent having a multi-layered coating adhered to its surface which can prevent restenosis and thrombosis at the implant site. The stent coating is comprised of two layers. The first layer is a polymeric coating with one or more biologically active agent(s) dispersed therein. The second layer is comprised of a hydrophobic heparinized polymer that inhibits blood coagulation and provides a hydrophilic surface for reducing the friction between stent and lesion site. In preferred embodiments of the invention, the multi-layered stent is effective in deterring restenosis and thrombosis at the implant site. In these same preferred embodiments, the multi-layered stent is capable of reducing the burst release of the biologically active agents from the first layer and sustaining a release of an effective amount of these agents for a relatively extended period of time. Methods of applying the multi-layered coating to the stent surface are also part of this invention.

Nanoscale Hydrogel Coatings on Cells. Abstract. The manipulation of biological function on the cellular and subcellular level holds great potential for innovation in medical diagnostics and treatment. Central to this manipulation is the interface of the biological species and its surroundings. Polymeric coatings are obvious choices for biointerfaces as they can mimic the biological environment in structure and chemical functionality and are readily tuned owing to their wide variation in architecture, mechanical properties, surface energy and transport properties.. This talk will focus on the formation of an interfacial polymer network as a tool to control transport of materials at a mammalian cell membrane. The discussion will be is focused on applications of cellular coatings for cellular sorting. An entirely new approach to cellular sorting will be presented that is based on the selective deposition of a protective coating on a cell and the destruction of all unprotected cells. This new batch ...

Adapting characteristics of biomaterials specifically for in vitro and in vivo applications is becoming increasingly important in order to control interactions between material and biological systems. These complex interactions are influenced by surface properties like chemical composition, charge, mechanical and topographic attributes. In many cases it is not useful or even not possible to alter the base material but changing surface, to improve biocompatibility or to make surfaces bioactive, may be achieved by thin coatings. An already established method is the coating with polyelectrolyte multilayers (PEM). To adjust adhesion, proliferation and improve vitality of certain cell types, we modified the roughness of PEM coatings. We included different types nanoparticles (NPs) in different concentrations into PEM coatings for controlling surface roughness. Surface properties were characterized and the reaction of 3 different cell types on these coatings was tested.

Various ceramic solutions are prepared from Al based precursors, solvent and chelating agent, the coating are fabricated on SS substrates. Al2O3 solution was successfully obtained using Al-sec-butoxide precursor, and isopropanol and acetylacetone as solvent and chelating agents, respectively. In order to improve adhesion of Al2O3 on the SS-304 tapes, triethanolamine was used in the solution. The residual stresses are investigated at different temperature ranges, between (630, 600, 580, and 550 degrees C) and room temperature for different thicknesses (12, 10 and 7 mu m). The maximum stress values are obtained as 0.756 GPa as tension on substrate (SS) for the 12 mu m coating and 1.0 GPa as compression for the 7 mu m Al2O3 coating at 630 degrees C. The surface morphology and microstructure of samples are characterized by a scanning electron ...

TY - JOUR. T1 - Understanding the influence of wood as a substrate on the permeability of coatings by NMR imaging and wet-cup. AU - Gezici-Koç, Ö.. AU - Erich, S.J.F.. AU - Huinink, H.P.. AU - van der Ven, L.G.J.. AU - Adan, O.C.G.. PY - 2018/1/1. Y1 - 2018/1/1. N2 - An important reason to apply coatings on wood is to protect wood against moisture. As a result of regulations and ecological concerns, there has been a shift towards waterborne coatings, which make coatings intrinsically more sensitive to water. As a consequence of the higher sensitivity to water, the durability of both wood and coatings can be negatively affected. In order to use waterborne coatings for woodcare, the main factors influencing transport through these coatings have to be understood. The aim of this study is to elucidate the influence of the wooden substrate on the water permeability of the coating applied to it. Pine sapwood, oak and teak were selected as the wood types, covering a whole range of low to high density ...

The research of hard protective coatings is distictively application-oriented, as the main goal is to increase the lifetime of tools in the machining environment. Optimal combination of properties required for hard coatings can only be achieved by an in-depth study in several levels: understanding the process of coating growth, analysis of influence of deposition parameters on coating properties, and analysis of coating wear processes. The topic is distinctively interdisciplinary, encompassing plasma physics, physics and chemistry of surfaces, metallurgy, materials science and mechanical engineering. Beside a targeted development of a coating for specific technological application, the study of above mentioned processes contributes to a general knowledge of deposition and application of hard coatings. The most important materials for hard coatings are transition metal nitrides, but the department is doing research on other materials such as diamond-like coatings, quasicrystals, oxides, etc. The ...
