Safety and Effectiveness Study of EverFlex Stent to Treat Symptomatic Femoral-popliteal Atherosclerosis
The US StuDy for EvalUating EndovasculaR TreAtments of Lesions in the Superficial Femoral Artery and Proximal Popliteal By usIng the Protege EverfLex NitInol STent SYstem II

This is a multi-center, non-randomized, single arm study to compare PTA and primary stenting using a single PROTÉGÉ® EverFlex™ stent to performance goals of PTA alone in the treatment of atherosclerotic superficial femoral artery (SFA) and proximal popliteal lesions.
