Filter by:Contrast ultrasound is a technique that can quantify blood flow in the tissues of the body by ultrasound detection of microbubble contrast agents that behave in the circulation similar to red blood cells. In this study, the investigators hypothesize that contrast ultrasound of blood flow in the leg (thigh and calf) at rest and during stress produced by medications that mimic exercise (vasodilator stress) can provide information on the location and severity of peripheral vascular disease (blockages of the blood vessels in the leg). The investigators will also determine whether symptom improvement after revascularization (procedures to open up or bypass the blockages) is directly related to the improvement in blood flow.
The principal aim of the study is to determine the effects n3-PUFA on top of standard therapy on surrogate markers of disease severity and/or prognosis in patients with PAD. Treatment duration will be 3 months, final follow-up is planned at 6 months after inclusion. Primary outcome parameter is endothelial function assessed by flow-mediated vasodilation using brachial artery ultrasound. Secondary outcome measures comprise maximum and pain-free treadmill walking distance, pulse wave velocity, whole blood viscosity, platelet activation and plasma markers of inflammation.
The DEFINITIVE AR study is a prospective, multi-center, randomized pilot study evaluating the use of either the TurboHawk™ or SilverHawk® plaque excision systems followed by treatment with the Cotavance™ drug-eluting balloon catheter versus the Cotavance balloon catheter alone in patients with peripheral arterial disease.
This is a clinical study of a new self-expanding stent (FlexStent®) designed specifically to cope with the extreme demands of the superficial femoral artery (SFA)/proximal popliteal artery. The arteries are often abbreviated as femoropopliteal. The intent of this study is to demonstrate that the FlexStent® Femoropopliteal Self-Expanding Stent System is safe and effective for the treatment of patients with peripheral arterial disease. Specifically, the FlexStent® shall meet or exceed the proposed safety and efficacy performance goals established for Femoropopliteal bare nitinol stents in patients with symptomatic peripheral arterial disease.

This randomized, post-market clinical study is intended to evaluate the delivery and deployment of longer Zilver PTX stents (≥ 100 mm) compared to shorter Zilver PTX stents (≤80 mm) for treatment of lesions of the above-the-knee femoropopliteal artery.
Purpose This study is to verify and validate PAD1 as a qualitative serum test which will combine the results of multiple assays into a single numeric result, to be determined by evaluation of the study data. PAD1 is an automated software device (PADCalc) that incorporates specific and multiple biomarker values found in human blood, and generates a score (PAD1 score) using a fixed formula implemented within the PADCalc software. The PAD1 score is a result with a high or low probability of PAD. PAD1 will be submitted to FDA as a 510(k) for in vitro diagnostic use in conjunction with clinical assessment, based on factors such as age, diabetes, smoking, and vascular laboratory tests (including the ABI), as an aid towards further evaluation of patients who meet the enrollment eligilbility criteria. Eligibility It is indicated for women and men considered at risk for PAD who meet the following criteria: a history of smoking and/or diabetes and are age 50 years or older, or 70 years of age or older. PAD1 is an aid to further assess the likelihood of the presence of PAD when used in conjunction with clinical assessment and vascular laboratory tests.
The intent of this clinical registry is to demonstrate the efficacy of the EPIC™ stent in patients with superficial femoral/ popliteal artery disease. 100 patients with symptomatic femoropopliteal artery lesion will be enrolled in the study and shall undergo 4 visits during the trial -a pre-procedure visit, procedure visit at which time the stent will be placed, and follow-up visits at 6 and 12 months. Study hypothesis: The EPIC™ Self-Expanding Nitinol Vascular Stent with Delivery System will be efficacious in patients with Superficial Femoro/Popliteal Artery disease.
The investigators are conducting a pilot study for a clinical research trial to establish the feasibility and acceptability of the intervention and the most effective recruitment strategies prior to the full study.
The purpose of the study is to evaluate the safety and efficacy of laser atherectomy with balloon angioplasty compared to balloon angioplasty alone in the treatment of above the knee peripheral artery in-stent restenosis.
