The Study to Compare SMART Nitinol Stent and Balloon Angioplasty

This is a multi-center prospective, randomized, two-arm study evaluating performance of the Cordis SMART™ Nitinol Stent System compared to balloon angioplasty. Patients will be randomized on a 1:1 basis. It is anticipated that a total of 120 patients will be entered into the study. Objective of the study is: Performance of the Cordis S.M.A.R.T.™ (CONTROL™) Nitinol Stent System for the treatment of superficial femoral artery (SFA) long de novo or restenotic lesions (≥ 70% stenosis or occlusions) in comparison with balloon angioplasty as determined by Binary Restenosis (≥50% restenosis based on a peak systolic velocity ratio ≥ 2.5) at one year as demonstrated by Duplex sonography.
