Peripheral Arterial Diseases, Superficial Femoral Artery Stenosis
Conditions
Keywords
PAD, SFA
Brief summary
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.
Detailed description
The SUMMIT Registry addresses the treatment of peripheral arterial disease (PAD). PAD represents a major challenge to physicians in treating the Superficial Femoral (SFA) and Popliteal arteries. These vessels are exposed to enormous mechanical stress what represents a harsh environment for any endovascular device. During flexing of the knee, the SFA/Popliteal arteries can bend, rotate, elongate and compress dramatically. An ideal stent designed for use in the SFA/Popliteal arteries would offer great ranges of movement while adequately supporting the arteries. Subject of study is the EPIC™ Femoropopliteal Self-Expanding Stent System which provides a great range of motions for a highly flexible femoral artery while adequately supporting the vessel. Primary objective is to evaluate the efficacy of the device in treating lesions of the SFA/Popliteal artery. The project is a multi-centre open label study. Primary efficacy parameter will be assessed by measuring the in-stent binary stenosis using duplex ultrasound at 6 and 12 months after the stent placement. Binary restenosis is defined as a peak systolic velocity ratio (PSVR) ≥2.5:1. Anticipated study duration is 18 months: 6 months recruiting and 12 months follow-up.

Inclusion criteria
* Subjects, male or female, must be between the ages of 18 to 85 years inclusive at the time of consent. A female of childbearing potential may be enrolled, provided she has a negative pregnancy test at Screening. * Subjects must give written informed consent prior to participation in the study and must understand the purpose of this study and be willing to adhere to the study procedures described in this protocol. * Rutherford Classification Category 2-4 * Single de novo lesion in the superficial femoro/popliteal artery * Disease segment length ≤150mm * \>70% diameter stenosis and occlusion * Patent ipsilateral iliac artery * Patent ipsilateral popliteal artery and at least 1 patent tibial artery in continuity to ankle * Target reference vessel diameter 3.5-7.5 mm
Exclusion criteria
