Brief Summary:
This is a prospective, multicenter, non-randomized, single-arm trial; the primary objective is to assess the comparability of the performance of the IDev SUPERA® nitinol stent to a rate derived from a meta-analysis of studies on iliac stents approved by FDA for treating subjects with de novo or restenotic lesions in the common and/or external iliac arteries.

Condition or disease Intervention/treatment Phase
With de Novo or Restenotic Lesions in the Common and/or External Iliac Arteries. Device: IDev SUPERA® Interwoven Self Expanding Nitinol Stent Peripheral Vascular System Phase 2 Phase 3

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 0 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Comparative Study of Safety and Efficacy of the SUPERA® Wire Interwoven Self-expanding Nitinol Stent and Currently Approved Stents for Patients With Iliac Lesions

Arm Intervention/treatment
Historical control
Device: IDev SUPERA® Interwoven Self Expanding Nitinol Stent Peripheral Vascular System
Interwoven, self-expanding nitinol stent system, including delivery system and stent

Primary Outcome Measures :
  1. Occurrence of death [ Time Frame: within 30 days post-procedure ]
  2. Target site revascularization or restenosis [ Time Frame: 9 months ]

Secondary Outcome Measures :
  1. Major adverse events (MAEs) [ Time Frame: 30 days ]
  2. Device success (delivery and deployment of the study stent and retrieval of the delivery system) [ Time Frame: During implantation procedure ]
  3. Acute procedural success [ Time Frame: immediately following stent deployment ]
  4. Early and late clinical success (Rutherford-Becker improvement); ABI and TBI improvement; symptom based. [ Time Frame: 30 days and 6, 9, and 12 months ]
  5. Target vessel patency [ Time Frame: 6, 9, 12, 24, and 36 months ]
  6. Quality of Life [ Time Frame: baseline, 3 and 6 months ]
