Vascular stent/grafts designed for deployment into one of the peripheral arteries, especially those that supply blood to the lower extremities, such as the iliac, femoral, and popliteal arteries. These devices typically consist of a balloon-expanded or self-expanding stent covered with a synthetic (e.g., polyurethane, Dacron) graft; they are available in several different shapes (e.g., straight, bend) to adapt to particular sections of the peripheral arteries and/or to prevent migration. Peripheral vascular stent/grafts are mostly used to treat aneurysms or pseudoaneurysms and/or to repair vessel perforations or ruptures. Some are used to keep open strictures of the vessels and/or to reduce vascular narrowing (i.e., restenosis) after angioplastic procedures.
