Filter by:The VISIBILITY Iliac study is a prospective, multi-center, non-randomized study confirming the safety and effectiveness of stenting using the Visi-Pro™ Balloon Expandable Stent System for the treatment of stenotic, restenotic or occluded lesions in the common and external iliac artery.
Sodium nitrite has been demonstrated to promote new blood vessel growth, speed up wound healing and prevent tissue necrosis in animals. Since patients with PAD experience many of these problems, this study will seek to determine whether this drug, when given orally, could provide the same benefits to patients with PAD.
The DURABILITY Iliac study is a prospective, multi-center, non-randomized study confirming the safety and effectiveness of stenting using the Protégé® EverFlex™ and Protégé® GPS™ Self-Expanding Stent Systems for the treatment of atherosclerotic lesions in the common and/or external iliac arteries.
To determine the safety and efficacy of the Omnilink Elite™ Peripheral Balloon-Expandable Stent System in subjects with atherosclerotic de novo or restenotic lesions in the native common iliac artery and/or native external iliac artery.
The purpose of this study is to evaluate the safety of administration of marrow-derived autologous hematopoietic stem cells (HSC) concentrate and platelet-rich plasma (PRP) gel for the treatment of Critical Limb Ischemia (CLI).
The specific aim of this study is to prospectively compare outcomes (functional, quality of life, risk-adjusted clinical event) of medical management, surgical or endovascular (angioplasty or stent placement) interventions for the treatment of claudication caused by peripheral arterial disease. This study will test two major hypotheses; Hypothesis 1: At 12-months, surgical interventions are associated with greater improvements in function, claudication symptoms, and health-related quality of life (HRQoL) than endovascular procedures or medical management. Hypothesis 2: At 12-months, surgical and endovascular interventions are associated with greater improvements in function, claudication symptoms, and HRQoL than medical management.
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.
