Intervention Details:
    Device: PROTÉGÉ® EverFlex™ Self-Expanding Stent System
    Implantation of a single study device in the native superficial femoral artery or superficial femoral artery and proximal popliteal artery.

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Stenotic, restenotic (from PTA or adjunct therapy, not including stents or stent grafts) or occluded lesion(s) located in the native superficial femoral artery or superficial femoral and proximal popliteal arteries.
  • Symptomatic femoral-popliteal atherosclerosis.
  • Willing to comply with all follow-up evaluations at the specified times.
  • Provides written informed consent prior to enrollment in the study.

Exclusion Criteria:

  • Previously implanted stent(s) or stent graft(s) in the target vessel.
  • Planned use of devices other than angioplasty balloons during procedure.
  • Received endovascular treatment of the target lesion (except stents/stent grafts) within six months of the index procedure.
  • Life expectancy of less than 12 months.
  • Symptomatic femoral disease in the opposite limb.
