This is a prospective, multicenter, randomized study designed to enroll 138 patients with superficial femoral artery stenosis and /or occlusion who will be randomized 1:1 to be treated with the Drug eluting peripheral vascular stent system versus the commercially available Nitinol Stent System (Cordis Corporation).
