The FORMAT Clinical Study is a clinical trial to evaluate the safety and effectiveness of the Formula™ 535 Iliac Balloon-Expandable Stent in treatment of symptomatic vascular disease of the iliac arteries.
The main aim of the study is to investigate, in humans, the effect of plant sterols on vascular function by measuring flow-mediated dilation (FMD). This study also aims to study the effect of plant sterols on pulse wave velocity (PWV), aortic augmentation index (Aix), central blood pressure (CBP), office blood pressure (BP), blood lipids and plasma plant sterol concentration. At last, the effects of plant sterols on z-scores of circulating biomarkers of endothelial dysfunction and low-grade inflammation will be assessed. For all study outcomes, effect sizes and 95% confidence intervals will be estimated. Hypothesis: Based on available evidence, it is hypothesized that plant sterols modestly increase FMD.
Biofilm has been identified as the major bacterial phenotype contributing to atherosclerosis. It has become very important to evaluate atherosclerosis and the role of biofilm using advanced technologies. It is also important to understand wound biofilm at a genetic and a molecular level.
This is a single-arm, single-center, open-label, pilot study . 30 subjects with foot symptoms attributable to diabetes or peripheral vascular disease will be screened . Subjects meeting inclusion criteria will sign informed consent and enrolled. All 30 subjects will be treated with the Magic Foot™. If there is any significant improvement in ICG or foot symptoms as obtained from self evaluation questionnaire, a further 30 subjects will be enrolled.
To evaluate the efficacy of combination therapy with ranibizumab (RBZ) and panretinal photocoagulation (PRP) versus PRP alone in patients with treatment-naive bilateral proliferative diabetic retinopathy (PDR) as measured by mean change in visual acuity (VA), mean change in central retinal thickness (CRT) as measured by time-domain optic coherence tomography (TD-OCT) and incidence of vitreous hemorrhage (VH).
Several studies have shown that stenting of the femoropopliteal artery in the lower leg leads to improved overall results compared to balloon angioplasty alone. However, scar tissue development can occur within the stent, a process called restenosis. Treatment of these in-stent restenotic lesions has a high procedural success rate but recurrence of scar tissue is frequently seen. Several methods have been proposed to treat in-stent restenosis in the lower leg arteries but mixed results have been noted. In this study we hypothesize that simultaneous tissue excision and aspiration using the JetStream Navitus device (Medrad) can lead to a high rate of acute procedural success with low intraprocedural complications and an acceptable recurrence rate of restenosis at 6-month follow-up.
ClarityIQ is a novel X-ray imaging technology, that combines advanced real-time image noise reduction algorithms, with state-of-the-art hardware to reduce patient entrance dose significantly. This is realized by anatomy-specific optimization of the full acquisition chain (grid switch, beam filtering, pulse width, spot size, detector and image processing engine) for every clinical task individually. Furthermore, smaller focal spot sizes and shorter pulses are used, which are known to positively influence image quality . The final effect on the clinical image quality is investigated in this study.
A multi-center, post-CE Mark study designed to evaluate the performance of the Intact Vascular Tack-IT Endovascular Stapler™ in subjects with vascular flaps (e.g.; post-angioplasty dissection) resulting from percutaneous transluminal balloon angioplasty (PTA) of superficial femoral or popliteal artery(ies).
The primary purpose of this study is to assess safety and efficacy of the Drug Eluting Balloon (DEB) technology for the treatment of the Superficial Femoral Artery (SFA) ischemic obstructive vascular disease in patients presenting with long lesions. As secondary aim this study is going to explore treatment effect on a number of procedural and clinical endpoints in order to collect information to design a future comparative effectiveness study.
