The purpose of this study is to assess the ability of a vascular stent to maintain an open iliac (leg) artery. The Zilver Vascular Stent is made of nitinol, a flexible metal with a long history of use in medical devices. The stent self-expands once inside the artery where it is intended to hold the vessel wall open. Within a few weeks, a layer of cells will grow over the stent helping to hold it in place.

Condition Intervention Phase
Peripheral Arterial Disease (PAD) Device: Peripheral Vessel Stenting Phase 2

Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
