Brief Summary:
The objective of this clinical investigation is to evaluate the short-term (up to 12 months) outcome of treatment by means of the self-expanding iVolution nitinol stent in symptomatic (Rutherford 2-4) femoropopliteal arterial stenotic or occlusive lesions.

Condition or disease Intervention/treatment Phase
Peripheral Arterial Disease Device: iVolution nitinol stent Phase 2 Phase 3

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 120 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: EVOLUTION STUDY, a Physician-inititated Trial Investigating the Efficacy of the Self-Expanding iVolution Nitinol Stent for Treatment of Femoropopliteal Lesions
Actual Study Start Date : April 2015
Actual Primary Completion Date : December 2017
Actual Study Completion Date : December 2017

Arm Intervention/treatment
Experimental: iVolution stent
Patient's treated with the iVolution stent from iVascular for the treatment of femoropopliteal lesions.
Device: iVolution nitinol stent

Primary Outcome Measures :
  1. Primary Patency at 12 months [ Time Frame: 12 months ]
    freedom from >50% restenosis at 12 months as indicated by an independently verified duplex ultrasound peak systolic velocity ratio (PSVR) <2.5 in the target vessel with no reintervention

Secondary Outcome Measures :
  1. Technical Success [ Time Frame: Procedure ]
  2. Primary Patency at 1 & 6 months [ Time Frame: 1 & 6 months ]
  3. Freedom from Target Lesion Revascularization (TLR) at 1, 6 and 12 months [ Time Frame: at all follow-up visits ]
  4. Clinical Success at 1, 6 and 12 months [ Time Frame: at all follow-up visits ]
    Clinical success at follow-up is defined as an improvement of Rutherford classification at 1-, 6- & 12-month follow-up of one class or more as compared to the pre-procedure Rutherford classification.

  5. Serious adverse events until follow-up completions [ Time Frame: 1,6,12 months and interem visits ]
    Any clinical event that is fatal, life-threatening, or judged to be severe by the investigator; resulted in persistent or significant disability; necessitated surgical or percutaneous intervention; or required prolonged hospitalization.
