<qa>  What is the true rate for the EPICTM Nitinol Vascular StentThis is a national, prospective, multi-center, non-randomized study to evaluate the long-term efficacy and integrity of the EPICTM Nitinol Vascular Stent System in Superficial Femoral Artery SFA lesions. A total of 100 patients will be included in approximately 10 sites. The study is designed to demonstrate the EPIC Nitinol Vascular Stent System is non- inferior to the published patency rates found in the literature. This non-inferiority will be established by proving that the true rate for the EPICTM Nitinol Vascular Stent System is higher than 82 minus a 10 delta.
