Treatment of in-stent restenosis with excimer laser coronary angioplasty versus rotational atherectomy: comparative mechanisms and results. (1/46)BACKGROUND: Atheroablation yields improved clinical results for balloon angioplasty (percutaneous transluminal coronary angioplasty, PTCA) in the treatment of diffuse in-stent restenosis (ISR). METHODS AND RESULTS: We compared the mechanisms and clinical results of excimer laser coronary angioplasty (ELCA) versus rotational atherectomy (RA), both followed by adjunct PTCA; 119 patients (158 ISR lesions) were treated with ELCA+PTCA and 130 patients (161 ISR lesions) were treated with RA+PTCA. Quantitative coronary angiographic and planar intravascular ultrasound (IVUS) measurements were performed routinely. In addition, volumetric IVUS analysis to compare the mechanisms of lumen enlargement was performed in 28 patients with 30 lesions (16 ELCA+PTCA, 14 RA+PTCA). There were no significant between-group differences in preintervention or final postintervention quantitative coronary angiographic or planar IVUS measurements of luminal dimensions. Angiographic success and major in-hospital complications with the 2 techniques were also similar. Volumetric IVUS analysis showed significantly greater reduction in intimal hyperplasia volume after RA than after ELCA (43+/-14 versus 19+/-10 mm(3), P<0.001) because of a significantly higher ablation efficiency (90+/-10% versus 76+/-12%, P = 0.004). However, both interventional strategies had similar long-term clinical outcome; 1-year target lesion revascularization rate was 26% with ELCA+PTCA versus 28% with RA+PTCA (P = NS). CONCLUSIONS: Despite certain differences in the mechanisms of lumen enlargement, both ELCA+PTCA and RA+PTCA can be used to treat diffuse ISR with similar clinical results. (+info)
Six-month clinical and angiographic outcome after successful excimer laser angioplasty for in-stent restenosis. (2/46)OBJECTIVES: This study evaluated the clinical and angiographic six-month follow-up after excimer laser coronary angioplasty (ELCA) for restenosed coronary stents. BACKGROUND: Excimer laser coronary angioplasty has recently been shown to be safe and efficient for the treatment of in-stent restenosis. METHODS: Ninety-six consecutive patients successfully treated with ELCA within 141 stents were included in a six-month clinical and angiographic follow-up. RESULTS: During follow-up there was one sudden death and one patient with documented myocardial infarction. Angina pectoris classified as > or = Canadian Cardiovascular Society II reoccurred in 49 patients. Follow-up angiography was obtained in 89 patients (93%) with 133 stents. Quantitative coronary angiography revealed a mean diameter stenosis of 77 +/- 10% before intervention, 41 +/- 12% after laser treatment and 11% +/- 12% after adjunctive percutaneous transluminal coronary angioplasty (p < 0.001). Six months after ELCA the mean diameter stenosis had increased to 60 +/- 26% (p < 0.001). A > or =50% diameter stenosis was present in 48 patients (54%); in 24 of these patients diameter stenosis was > or =70%. Total occlusions occurred in an additional 10 patients (11%). There was a trend toward an increased recurrent restenosis rate in patients with diabetes mellitus and long lesions or total occlusions (p = 0.059). Forty-eight patients (50%) received medical treatment after six months. Reinterventions were necessary in 30 patients (31%), and coronary artery bypass surgery was performed in 17 patients (18%). Event-free survival was 50%. CONCLUSIONS: Excimer laser angioplasty for in-stent restenosis was associated with a high incidence of recurrent restenosis in this group of patients, suggesting that this technique is unlikely to reduce recurrent in-stent restenosis and that other approaches are necessary.

Clinical and angiographic outcome in patients with in-stent restenosis and repeat target lesion revascularisation in small coronary arteries. (3/46)OBJECTIVE: To evaluate the clinical and angiographic outcome in patients with in-stent restenosis in small coronary arteries and repeat target lesion revascularisation. DESIGN: Patients with in-stent restenosis in coronary arteries < or = 2.85 mm were eligible for the study and underwent target lesion revascularisation. Clinical and angiographic variables were assessed during a six month follow up period. RESULTS: 73 patients with 79 lesions were treated by percutaneous transluminal coronary angioplasty (47%), excimer laser angioplasty (25%), or restenting (28%). The mean (SD) reference diameter before target lesion revascularisation was 2.12 (0.5) mm. Procedural success was achieved in all cases, but 57% of the patients had restenosis after six months. The rate of further restenosis was higher with laser angioplasty (78%) than with restenting (47%) or balloon angioplasty alone (49%, p < 0.05). CONCLUSIONS: Treatment for in-stent restenosis in small coronary arteries is feasible and safe, with a second restenosis rate comparable to large coronary artery series. The strategy of target lesion revascularisation influences further in-stent restenosis, with an increased rate with laser angioplasty compared with restenting and repeat dilatation alone. (+info)
Treatment of in-stent coronary restenosis with excimer laser angioplasty. (4/46)OBJECTIVE: To evaluate the efficacy and safety of excimer laser coronary angioplasty (ELCA) with adjunctive balloon angioplasty in patient with in-stent restenosis. METHODS: ELCA was performed in 20 patients of instent restenosis. All patients were symptomatic and had class III-IV angina. ELCA was performed with the Spectranetics CVX-300 System. The laser catheter of Vittesse C (concentric) and E (eccentric) with diameter of 1.4-2.0 mm was used. RESULTS: Laser catheter crossed all stenotic stents without difficulty. The lesion length was 4.6-51.2 mm, mean 20.7 +/- 13.7 mm, including 14 lesions > 10 mm. Laser treatment alone increased minimal lumen diameter (MLD) from 0.3 +/- 0.3 mm to 1.4 +/- 0.3 mm (P < 0.0001) and improved the diameter stenosis from 88.8% +/- 10.0% to 46.0% +/- 8.0% (P < 0.0001). Adjunctive balloon angioplasty further increased minimal lumen diameter to 2.3 +/- 0.7 mm and reduced diameter stenosis to 14.2% +/- 8.2% (P < 0.0001). At follow-up (1-17 months, mean 8.9 +/- 5.7 months), 17 (85%) patients had remained asymptomatic, 3 (15%) patients had mild to moderate exertional angina, 1 (5%) patient received CABG. CONCLUSION: ELCA with adjunctive percutaneous transluminal coronary angioplasty (PTCA) is an efficient and safe technique to debulk tissue in the patient with in-stent restenosis. The incidence of procedural related complication was low and ELCA may be used as a good method for in-stent restenosis treatment. (+info)
Coronary flow velocity and disturbed flow predict adverse clinical outcome after coronary angioplasty. (5/46)OBJECTIVE: Laminar flow becomes disturbed at high velocities, reducing shear stress and augmenting vascular inflammation and proliferation, processes that are pivotal in restenosis and atherogenesis. We hypothesized that disturbed blood flow after coronary angioplasty is associated with adverse long-term clinical outcome. METHODS AND RESULTS: The cineangiograms from 97 patients undergoing laser-assisted coronary angioplasty were analyzed. Coronary blood flow velocity, the residual lesion dimensions, and the Reynolds number (an index of disturbed flow) were measured by using a frame-counting technique and quantitative coronary angiography. Cox proportional hazards were used to assess the relative risk of adverse events (target-vessel revascularization, myocardial infarction, or death) over a mean 2.5 years after the index procedure. There were 41 adverse events during 245 patient years of follow-up (17% per year of follow-up). The risk of an adverse event was increased for patients with a high flow velocity (>250 mm/s; relative risk 2.5, 95% CI 1.3 to 4.7) or a high Reynolds number (>200) at the stenosis inlet (relative risk 2.1, 95% CI 1.1 to 4.1) at the end of the procedure. Adjustment for other factors did not alter these results. CONCLUSIONS: High Reynolds numbers, indicating disturbed blood flow after coronary angioplasty, increase the risk of adverse clinical events, potentially through shear-stress-related molecular mechanisms that promote restenosis and atherogenesis.

Excimer laser-assisted high-flow extracranial/intracranial bypass in patients with symptomatic carotid artery occlusion at high risk of recurrent cerebral ischemia: safety and long-term outcome. (6/46)BACKGROUND AND PURPOSE: The goal of this study was to determine safety and long-term outcome of the excimer laser-assisted high-flow extracranial/intracranial (EC/IC) bypass in patients with symptomatic carotid artery occlusion (CAO) at high risk of recurrent stroke. METHODS: In a prospectively collected cohort of 103 patients with symptomatic CAO, 15 patients were selected for excimer laser-assisted EC/IC bypass surgery on the basis of predefined selection criteria: (1) transient or moderately disabling symptoms of focal cerebral ischemia, not symptoms of the retina only; (2) continuing symptoms after documentation of the CAO; (3) evidence of a possible hemodynamic origin of symptoms; and (4) informed consent of the patient. RESULTS: Eleven patients underwent the operation without complications One patient had a severely disabling stroke (Rankin grade 4) 11 days after the operation; the bypass was found occluded on reoperation. Two other patients had a moderately disabling stroke (Rankin grade 3) immediately after the operation. One patient died of myocardial infarction 1 day after surgery. Median follow-up time was 27 months. Of the 11 patients who underwent the operation without complications, 1 died 17 months after the operation of a brainstem stroke, and another patient had a new stroke ipsilateral to his CAO 10 months after the operation but without a change in Rankin grade. CONCLUSIONS: The excimer laser-assisted high-flow EC/IC bypass operation is a potentially promising procedure in patients with symptomatic CAO and a presumably high risk of recurrent stroke, but the procedure carries a definite risk. This risk is probably related not only to the procedure itself but also to the selection of patients. (+info)
Treatment of in-stent restenosis with excimer laser coronary angioplasty. (7/46)Diffuse in-stent restenosis remains an important problem in percutaneous transluminal coronary angioplasty (PTCA). In this trial, we studied the early and mid-term outcomes of excimer laser coronary angioplasty (ELCA) on diffuse in-stent restenosis. ELCA was performed in 23 patients (19 males). The mean length of the lesions was 14.3 +/- 3 mm and the mean age was 58 +/- 7 years. The minimal lumen diameter (MLD) was measured by on-line quantitative coronary angiography. Before the procedure, MLD was 0.9 +/- 0.4. The Q/non-Q-wave myocardial infarction (MI), coronary artery bypass graft (CABG), PTCA, and mortality were recorded during the procedure and at 6 months follow up. The fluence of laser emission was 45 mj/m2 and the repetition rate was 25 pulses per second. Adjunctive balloon angioplasty was performed in all of the cases at a mean 7 +/- 2 atm pressure. The procedure was successfully performed in all of the cases. Type-B dissection developed, after ELCA in 1 patient (4%). Perforation, death, cerebrovascular accidents, emergency CABG, PTCA or Q/non-Q wave myocardial infarction were not observed. MLD was 0.9 +/- 0.4 mm before ELCA, 1.8 +/- 0.9 mm (P<0.05) after ELCA, and 3.1 +/- 0.7 mm after PTCA. At 6 months follow up, there were 2 (8.7%) Q-wave myocardial infarctions and 2 (8.7%) recurrent anginal pain cases. Control angiography was obtained in 20 cases (87%). Control angiography was not accepted by 3 patients. Their maximal exercise test was negative. Angiographic restenosis was observed in 6 cases (30%). The rate of target lesion revascularization (TLR) was 5 of 23 (22%) in the patients treated with ELCA. It is concluded, ELCA is a safe and efficient debulking technology for treating diffuse in-stent restenosis. (+info)
Intracoronary ultrasound predictors of adverse outcomes after coronary artery interventions. (8/46)OBJECTIVES: The purpose of this study was to determine the association between qualitative and quantitative lesion characteristics as assessed by intracoronary ultrasound imaging and adverse outcomes after coronary artery interventions. BACKGROUND: Restenosis and other adverse outcomes after coronary artery interventions may be difficult to predict from clinical or angiographic data. Intracoronary ultrasound imaging provides additional data that could prove useful. METHODS: Immediately after successful coronary artery interventions (angiographic residual stenosis < or = 50%), 69 patients underwent intracoronary ultrasound imaging. Images were assessed qualitatively for plaque composition and topography and for dissection. Quantitative data included measurement of minimal lumen diameter, lumen area, plaque area and percent area stenosis at the treatment and adjacent reference sites. Adverse outcome was defined as death, coronary bypass surgery, myocardial infarction or angiographic restenosis. RESULTS: Of the 69 patients, 1 died, 3 had bypass surgery and 1 had a myocardial infarction before planned 6-month repeat catheterization. Two patients were lost to follow-up study. Of the remaining 62 patients, 56 (90%) agreed to follow-up catheterization and 25 (45%) of the 56 had restenosis. Thus, 30 patients had an adverse outcome and 37 had no adverse event. The incidence of dissection detected by ultrasound imaging after an intervention was significantly greater in patients with than in those without a subsequent adverse event (63% vs. 35%, p < 0.05). The severity of dissection also appeared to be related to outcome (p < 0.05). Other qualitative and quantitative variables were not significantly different between the two patient groups. CONCLUSIONS: Dissection, as assessed by intracoronary ultrasound imaging after a coronary artery intervention, can identify patients at increased risk of subsequent adverse events. Additional studies are warranted to explore whether such imaging may allow modification of interventional procedures to improve outcome. (+info)

Laser atherectomy might decrease procedural complications during percutaneous coronary intervention (PCI) of degenerated saphenous vein grafts (SVGs) in case of unstable or thrombotic lesions because of its ability to debulk and vaporize thrombus. We aimed at prospectively evaluating the safety and efficacy of excimer laser coronary angioplasty (ELCA) as a primary treatment strategy in consecutively unstable patients undergoing PCI of degenerated SVG lesions. Seventy-one consecutive patients with non-ST elevation acute coronary syndrome (mean age 69 ± 10 years, 66 men [89%]) undergoing PCI of degenerated SVG were enrolled in a prospective case-control registry, using 2 different distal protection devices (DPDs; FilterWire EZ [Boston Scientific, Natick, Massachusetts; n = 24] and SpiderRX [Ev3, Plymouth, Minnesota; n = 23]) or ELCA (n = 24 ...

From February to August 1997, 64 patients were enrolled in a study of intracoronary gamma radiation for in-stent restenosis. In the present study, we analyzed 37 lesions (31 native coronary and 6 vein graft) in 36 patients (age, 62±10 years; 24 men) previously treated with Palmaz-Schatz stents (Cordis). Reasons for exclusion were restenting of the lesions (n=13), no delayed (n=6) or inadequate IVUS (n=1), in-stent tissue ,75% of stent cross-sectional area (CSA; n=2), restenosis localized to stent margin(s) (n=1), or presence of non-Palmaz-Schatz stents (n=5). (One patient had 2 lesions; per protocol, only 1 was enrolled in the radiation trial.) There were 65 stents (1.8 per lesion), implanted 9.6±8.3 months previously. Fifteen patients (40%) had prior in-stent restenosis; the last episode was 5.5±3.3 months previously.. Primary treatment strategy was determined by the operator: PTCA (n=8), excimer laser coronary angioplasty (ELCA; Spectranetics; n=12) + adjunct PTCA, or rotational atherectomy ...
The goal of this study was to validate the CT MCA dot sign, including direct comparison with the gold standard of conventional cerebral catheter angiography. Angiographic comparison demonstrated that the MCA dot sign clearly has diagnostic value as a highly specific and moderately sensitive indicator of acute thrombus or slow flow within the M2 or M3 branches of the MCA. In addition, in our analysis, both the MCA dot sign and the HMCA sign demonstrated good interrater reliability. We detected the presence of an MCA dot sign on CT in 16.7%, similar to the 16% incidence observed by Barber and colleagues16 in their acute stroke patient population.. The MCA dot sign also demonstrated good prognostic value. The presence of an isolated MCA dot sign, an MCA dot sign in conjunction with an HMCA sign, or an isolated HMCA sign were all associated with more severe neurological deficits at the time of patient presentation than the absence of any CT-visible intraluminal thrombosis. There was a trend for ...

A fiber-optic waveguide, used for ablating lesions in blood vessels, is mounted within and guided by a catheter having multiple lumens extending therethrough and parallel to each other. The waveguide fits within at least one lumen and a guidewire, previously inserted in a blood vessel, extends through another lumen. The distal end of the waveguide can have a short section of larger diameter fiber fused to it to cause a laser beam transmitted through the fiber to expand as it emerges from the waveguide to provide a larger ablation area. The waveguide may also be connected to an energy source by means of an energy coupler.

Balloon-Assisted Dislodgement of a Trapped Directional Atherectomy Catheter During Treatment of In-Stent Restenosis |...
However, being able to visualize the vessel with the lumivascular technology is clearly appealing and suggestive of safe passage. Distal embolization remains a major concern (especially atherectomy for ISR), and questions the need for embolic protection every time (filter was used only in 22% of patients in the DEFINITVE LE trial).7 Unprecedented complications can arise, which require expertise and catheter skills and may lead to the possibility of open vascular surgery in these high-risk patients.. DA in ISR lesions have been contraindicated due to the potential risk of cutter entrapment on stent struts during atherectomy. However, with the advent of concurrent imaging during DA, this risk can potentially be avoided. Nevertheless, as seen in this case, despite adequate visualization with OCT imaging, there can be significantly malapposed stent struts in overlapped segments that may still pose a risk for trapping the DA catheter. In such scenarios, the use of adjunctive balloon angioplasty ...
Two Cases of Coronary Stent Thrombosis Very Late After Bare-Metal Stenting | JACC: Cardiovascular Interventions
Medical literature has recently focused on very late stent thrombosis (VLST) after drug-eluting stent implantation, while its mechanistic issue was not fully explored in the bare-metal stent (BMS) era. The first case is a 59-year-old man presenting with inferior non-ST-segment elevation myocardial infarction, 4 years after BMS implantation (NIR 3.5/18 mm, Boston Scientific, Galway, Ireland) for a chronic total occlusion lesion in the proximal right coronary artery. Coronary angiograms showed Thrombolysis In Myocardial Infarction (TIMI) flow grade 1 and filling defects in the BMS deployed previously, and massive red thrombi attaching to uncovered stent struts were found by angioscope (Fig. 1,Online Video 1). Thrombectomy and adjunctive balloon angioplasty were performed based on the angioscopic findings, and TIMI flow grade 3 was obtained. The second case is a 71-year-old man who was admitted for a diagnosis of inferior non-ST-segment elevation myocardial infarction 10 years after a treatment ...

The biological effects of excimer lasers and safety associated with their use were discussed. Excimer lasers operate in the 193 to 351 nanometer (nm) wavelength range producing short pulses of high energy ultraviolet (UV) radiation. They have been used to ablate tissues and nonbiological material to a small depth. As excimer lasers produce radiation in wavelengths where mutagenic and carcinogenic
A rare gas-halogen excimer laser in which the laser gases are exposed virtually only to metal and ceramic, thereby reducing contamination of the gases and optics. In one preferred embodiment magnetic fluid seals (56) are used to isolate the bearings (58) supporting the shaft (46) upon which the tangential fan (44) rotates so that the lubricated bearings do not contaminate the laser gases. The fan (44) uses magnetic coupling (70, 76) so that an isolating enclosure may be placed over the seal to prevent the leakage of gases into the environment should the seal fail. An excimer laser that is therefore both safe enough to be used in medical and industrial applications as well as reliable may be fabricated.
Abstract 12989: Generalizability of Quantitative Angiographic In-Segment Late Lumen Loss Imaging in Eastern and Western...
Background: Regulators require mechanistic observations of late lumen loss (LLL) in evaluating new drug eluting stents (DES). Redundant requirements for follow-up catheterization across regulatory jurisdictions worldwide could be reduced if independent core laboratory quantitative coronary angiography (QCA) findings were generalizable. Our study aim was to assess comparability of QCA LLL in East (Japan, China) and West (N. America, Europe) pts using the worlds largest compilation of late follow-up QCA data.. Hypothesis: The propensity adjusted mean difference in QCA in-segment LLL between East and West is ≤0.4mm, with 95% confidence.. Methods: All available data from 4 manufacturers (7157 pts, 29 trials) reporting 6-12mo QCA LLL were compiled. East vs West were compared unadjusted and via propensity score (PS) quartiles that adjusted for 26 clinical descriptive and anatomic variables affecting QCA LLL. Of the 7157 pts, 6163 (86%) had complete covariable profiles and comprised the analysis ...

Evidence-based recommendations on percutaneous laser atherectomy with balloon angioplasty (with or without stenting) for peripheral arterial disease (PAD)
This forms a population inversion between the two states. Most excimer lasers are of the noble gas halide type, for which the term excimer is strictly speaking a misnomer (since a dimer refers to a molecule of two identical or similar parts): The correct but less commonly used name for such is exciplex laser. The wavelength of an excimer laser depends on the molecules used, and is usually in the ultraviolet: Excimer lasers, such as XeF and KrF, can also be made tunable using a variety of prism and grating intracavity arrangements. Excimer lasers are usually operated with a pulse rate of around 100 Hz and a pulse duration of ~10 ns, although some operate as high as 8 kHz and 200 ns. For electric discharge pump see: Nitrogen laser. The high-power ultraviolet output of excimer lasers makes them useful for surgery (particularly eye surgery), for lithography for semiconductor manufacturing, and for dermatological treatment. However, when in an excited state (induced by an electrical discharge or ...
Excimer: Ablation on Human Hair The unparalleled precision of the excimer laser makes it uniquely suited to the task of refractive corneal surgery. Each pulse of the laser removes 0.25 microns of tissue. Think of it as slicing 1/200 of a human hair, 1/28 of a red blood cell, or 1/39 millionth of an inch in 4 billionths of a second. This allows the surgeon to literally sculpt the cornea, gently and precisely, into a more desirable shape that allows rays of light to focus properly on the retina.. Myopic Correction. As explained previously, patients with nearsightedness have corneas that are too steep for the length of their eyes. The excimer laser is used to flatten the cornea so that the light rays that pass through it come to a point of focus on the retina, rather than in front of it.. Hyperopic Correction. Patients with hyperopia have corneas that are too flat for the length of their eye. The excimer laser is used to steepen the cornea so that light rays are focused on the retina, rather than ...
Prospective, Randomized, Multicenter Comparison of Laser-Facilitated Balloon Angioplasty Versus Stand-Alone Balloon Angioplasty...
Several limitations of this study must be acknowledged: 1) Given the relatively small sample size, the study was powered to show only major differences between the two treatment arms. Lesser degrees of benefit favoring laser-assisted PTCA or stand-alone PTCA may have gone undetected. However, given the higher rate of complications and slightly worse long-term outcomes with lasing in this trial, it is unlikely that enrolling a larger population would have revealed significant long-term benefits in the laser arm. 2) Although the two treatment arms were well matched for most baseline characteristics, several differences were present between the two groups, including the frequency of previous MI and the presence of thrombus-containing lesions. However, when analyzed separately and adjusted for by multivariate analysis, these factors had no bearing on acute or late event-free survival. 3) Some degree of selection bias cannot be excluded, especially in investigator reporting of clinical events and ...

TY - JOUR. T1 - Solid-state, pulsed-wave, mid-infrared coronary laser angioplasty in de novo versus restenosis lesions. T2 - Observations from a multicenter study. AU - Topaz, O.. AU - McIvor, M.. AU - De Marchena, Eduardo. PY - 1995/10/1. Y1 - 1995/10/1. N2 - The following is a study of the response of de novo versus restenosis coronary lesions to pulsed-wave, mid-infrared (holmium:YAG) laser assisted angioplasty. De novo lesions contain thrombi, cholesterol, and fibrosis, whereas restenotic lesions are composed of smooth muscle cells corresponding to injury caused by preceding balloon inflations. It is not known whether the different composition affects results of treatment by laser. In a clinical multicenter study, a mid-infrared, solid-state, pulsed-wave laser (holmium:YAG, 2.1 μm wavelength, 250-600 mJ/pulse, 5 Hz) was applied for revascularization of de novo and restenosis coronary lesions. Analysis of data was undertaken to document laser success, complications, and restenosis rate and ...
Alumina gamma-phase excimer laser synthesis: phenomenology of the process and properties of the material | (1995) | Laude | ...
Excimer laser sources have already been used with success for a number of novel material processing procedures. Most promising of these deal effectively with challenging materials for which little can be done with ordinary tools in order to materialize their potential. In this presentation, attention is focused on excimer irradiation processing of high grade sintered alumina. On one hand, it is shown how effective and unique can be an excimer beam in transforming the surface of this heavily used material. Under specific irradiation conditions, surface melting of sintered alumina is obtained. The resulting material is then studied by low-angle X-ray diffraction which reveals in particular the eventual formation of the uncommon gamma-alumina phase within 10 nm from the material surface. On the other hand, a rather thorough investigation of the phenomenology of the gamma-phase synthesis is presented, stressing various aspects: dynamic, energetic, structural and chemical, all of them stemming from ...
Excimer laser annealing (ELA) of As-, B- and BF2-implanted Si has been studied by secondary ion mass spectrometry (SIMS), spreading resistance probe (SRP) and transmission electron microscopy (TEM). The implantations have been performed in the energy range from I to 30 keV with doses of 10(15)-10(16) cm(-2). ELA has been carried out with the energy densities in the range of 600-1200 mJ/cm(2) and the number of laser pulses from 1 to 10. It is shown that ELA results in a more uniform dopant distribution over the doped region with a more abrupt profile edge as compared to those after rapid thermal annealing (RTA). Besides, in contrast to RTA, ELA demonstrates a highly confined annealing effect, where the distribution of dopants below the melting region is not affected. SRP measurements demonstrate almost complete activation of the implanted dopants after ELA, and TEM does not reveal extended defects in the ELA-treated samples. The depth of the doped layers, abruptness of the profiles and the total ...
We report the successful operation of a visible optical parametric oscillator (OPO) that uses urea as the nonlinear medium and is pumped in the near field of an injection-seeded pulsed XeCl excimer laser operating at 308 nm The OPO can generate continuously tunable radiation from 537 to 720 nm with a single set of dichroic mirrors and conversion efficiencies as high as 37% have been achieved in a 15-mm-long crystal at 90° phase matching. The influence of crystal double refraction (and hence beam walk-off) on the conversion efficiency across the OPO tuning range is discussed, and some oscillator parameters, including spectral linewidth and temporal behavior are characterized.. © 1989 Optical Society of America.

1994 - Benefit-risk trade-off was found for stent vs. balloon coronary angioplasty | 1995 Jan-Feb : Volume 122, Number 1, Page...
Coronary artery restenosis after balloon angioplasty occurs in 30% to 50% of patients. More than 50 randomized trials have failed to show a successful pharmacologic intervention, and the first 2 trials with directional atherectomy (1, 2) produced equivocal results. In these 2 stent trials, the angiographic results were remarkably similar for both post-procedural and follow-up minimum luminal diameter and percent diameter stenosis. Each showed an absolute 10% reduction in angiographic restenosis with stenting, a significant advance in this field. The clinical outcome results can be interpreted in various ways. A more negative analysis than that presented by the authors can be summarized by tabulating the results for stenting rather than angioplasty in 100 patients. In the Benestent study, 10 patients were spared repeat angioplasty at a cost of 1 extra acute coronary artery closure, 2 more bypass operations, 10 extra bleeding or vascular complications, and 540 additional acute hospital days.

An excimer gas laser using a fluorine/krypton/neon gas mixture is provided with separate fluorine/krypton/neon and krypton/neon gas sources for use in replenishing the gas mixture. A bleed-down mechanism is also provided for draining a portion of the gas mixture from the excimer laser. A control mechanism controls operation of the separate fluorine/krypton/neon and krypton/neon sources and the bleed-down mechanism to selectively vary the gas mixture within the excimer laser to maintain an overall optimal laser efficiency. Preferably, the control system monitors operational parameters of the excimer laser including gain, wavelength, bandwidth and pulse rate, to determine whether the gas mixture within the excimer laser may have changed from an optimal mixture. The control system controls operation of the separate fluorine/krypton/neon and krypton/neon sources to compensate for changes in the operation parameters of the laser to thereby maintain high overall laser efficiency.

An atherectomy device is used for removing a restriction in a blood vessel. The atherectomy device includes a cutting portion having a lumen therein, the lumen being sized to track over a guidewire, wherein an outer surface of the cutting portion comprises a cutting surface. An elongate shaping member is cooperable with the cutting portion and is disposed generally longitudinally relative to the cutting portion. The shaping member has an insertion conformation and an expanded conformation. The expanded conformation is radially expanded relative to the insertion conformation. The shaping member is configured to deform the cutting portion from an insertion shape into a cutting shape as the shaping member moves from the insertion conformation to the expanded conformation. A drive shaft is coupled to a proximal end of the cutting portion and is configured to be rotationally driven.
Renewable energy has become the preferred source to replace the ever-depleting conventional energy sources. Photovoltaics, commonly known as solar cells, have been an attractive option in this regard, but their high cost and relatively low efficiency compared to conventional power generation techniques has prevented widespread application. Silicon has been the most widely used photovoltaic material for decades. Thin film solar cells have become an attractive alternative for the conventional bulk crystalline solar cells since they are cheaper to produce. However, the thin film counterpart of crystalline silicon, known as hydrogenated amorphous silicon (a-Si: H), has its drawbacks in photovoltaic applications. The use of excimer lasers for crystallisation of a-Si: H has been widely investigated for microelectronic applications. This thesis is concerned with excimer laser crystallisation of comparatively thick a-Si: H films for photovoltaic applications. Films thicker than 300 nm, which are ...

LASIK is "hybrid" procedure, combining the ALK technique with the accuracy of the Excimer Laser. First the doctor will use an instrument called a Hansatome Microkeratome to create a thin surface-flap under a microscope this will only take a few seconds. Then the Excimer Laser, which has been pre-programmed with your exact correction, applies a rapid, cool ultraviolet light that precisely sculpts a very small amount of the sub-surface of the cornea. These short laser pulses correct the curvature of the cornea, allowing images to be focused clearly on the retina. The flap is then smoothed back down where it quickly bonds back in place, restoring a smooth, intact surface. ...

Charles Porterfield Krauth's Three Steps to Doctrinal and Ecclesial "Nihilism" | Steadfast Lutherans
I opine that the ELCA and other Liberal Protestant church bodies are in the third stage. It only takes a look at an ELCA seminary web-site to actually read Krauths assertion that error, "…puts men into positions, not as at first in spite of their departure from the Churchs faith, but in consequence of it.". My question: where is the LCMS in those 3 stages? My conjecture is she lies somewhere between stages 1 and 2, or even in stage 2. I hope I am wrong.. But my central and crucial question is: What of the response? Rev. Krauth states the way through this dark night with the conditional clause, "…if she be faithful to the Captain of her salvation." One way is prayer. This is His response. Our Captain commands it, gives us His Words to pray and Himself intercedes for the saints.. It was an inestimable blessing to me to have been part of the Society of the Holy Trinity since its founding. I think that the central and crucial part of the Societys Rule has been and is the Chapter retreats and ...

A comparative study of corneal incisions induced by diamond and steel knives and two ultraviolet radiations from an excimer...
This paper reviews the potential role of excimer lasers in corneal surgery. The morphology of incisions induced by two wavelengths of excimer laser radiation, 193 nm and 248 nm, are compared with the morphology of incisions produced by diamond and steel knives. Analysis suggests that ablation induced by excimer laser results from highly localised photochemical reactions and that 193 nm is the optimal wavelength for surgery. The only significant complication of laser surgery is loss of endothelial cells when incisions are within 40 micron of Descemets membrane. ...
Polymers | Free Full-Text | Internal Dynamics of Dendritic Molecules Probed by Pyrene Excimer Formation
This review exposes the current poor understanding of the internal segmental chain dynamics of dendrimers in solution probed by monitoring the process of excimer formation between pyrene labels covalently attached to the chain ends of dendrimers. The review begins by covering the bases of fluorescence and the kinetics of pyrene excimer formation before describing a procedure based on the Model Free (MF) analysis that is used to analyze quantitatively the fluorescence decays acquired for dendrimers, the ends of which have been fully and covalently labeled with pyrene. Comparison of the various trends obtained by different research groups describing the efficiency of pyrene excimer formation with the generation number of dendrimers illustrates the lack of consensus between the few studies devoted to the topic. One possible reason for this disagreement might reside in the presence of minute amounts of unattached pyrene labels which act as potent fluorescent impurities and affect the analysis of the

Excimer laser annealing technique has been proposed in the fabrication of low temperature polycrystalline silicon (LTPS) in the recent years, in particular for the applications to active-matrix liquid crystal display (AMLCD) . In comparing with the traditional thin film transistors (TFTs), the most attractive property of the laser annealed polycrystalline silicon is due to its relatively larger grain size and higher electron-hole mobility. Therefore, the embedded driving circuit could be easily achieved for replacing the additional driving integration circuits (IC) in LCD. It is known that circuit models play important role in the design of the embedded driving circuit using laser annealed LTPS TFTs. Unfortunately, most of mobility models are valid only for some conventional TFTs and can not be applied to the simulation of the laser annealed LTPS TFTs  accurately. In this work, we propose a unified mobility model which is suitable for the simulation of both the n- and p-type laser annealed LTPS
An absorption characteristic and a thermal relaxation time of a target biomedical tissue is an important parameter for development of low-invasive treatment that considers of interaction between biomedical tissue and laser. Laser irradiations with a wavelength corresponding to the absorption characteristics of tissue enable selective treatment. Furthermore, the thermal effect to tissue can be controlled at the laser irradiation time which depends on the laser pulse width and reception rate. A free electron laser (FEL) can continuously vary the wavelength in the mid-infrared region, has a unique pulse structure; the structure at the Institute of the Free Electron Laser (iFEL) consist of train of macropulses with a 15 &mgr;s pulse width, and each macropulse contained a train of 300-400 ultrashort micropulse with a 5 ps pulse width. In a previous report, we have proposed a novel laser treatment such as soft tissue cutting, dental treatment and laser angioplasty using the tenability of the FEL. To ...

Sequence illustrating the steps of balloon angioplasty in an artery suffering from Atherosclerosis. This procedure guides a deflated balloon into the narrowed artery. The balloon is inflated and as a result crushes the plaque into the walls of the artery. The balloon is deflated and removed leaving the passageway open for easy blood flow. Image 2 of 4. The pathology this procedure is used for is shown in images BP4210 and BP4211. - Stock Image C007/5682
ECCENTRIC ABRADING HEAD FOR HIGH-SPEED ROTATIONAL ATHERECTOMY DEVICES - The invention provides a rotational atherectomy device having, in various embodiments, a flexible, elongated, rotatable drive shaft with at least one flexible eccentric enlarged abrading head attached thereto. In other embodiments, the eccentric abrading head is not flexible or partially flexible. At least part of the eccentric enlarged cutting head has a tissue removing surface-typically an abrasive surface. In certain embodiments, the abrading head will be at least partially hollow. When placed within an artery against stenotic tissue and rotated at sufficiently high speeds the eccentric nature of the enlarged cutting head causes the cutting head and drive shaft to rotate in such a fashion as to open the stenotic lesion to a diameter substantially larger than the outer diameter of the enlarged cutting head. Preferably the eccentric enlarged cutting head has a center of mass spaced radially from the rotational axis of the ...
