Comparative Study Of Safety And Efficacy Of The SUPERA® Nitinol Stent - Iliac Artery

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.

3. The target lesion(s) is highly calcified or was previously treated with a stent.
4. Subject has a pre-existing target iliac artery perforation or dissection of the target iliac artery prior to initiation of the IDev implant procedure.
5. Subject has an abdominal aortic aneurysm contiguous with the iliac artery target lesion. Subject has a pre-existing aneurysm or dissection of the target iliac segment.
6. Subject with aortic or iliac aneurysm that is likely to require repair within the next 9 months.
7. Subject has a post-surgical stenosis and anastomotic suture treatments of the target vessel.
8. Subject has a vascular graft previously implanted in the native iliac vessel.

11. Subject has contrast agent hypersensitivity that cannot be adequately pre-medicated, has a hypersensitivity to nickel, or has intolerance to antiplatelet, anticoagulant, or thrombolytic medications.
12. Subject has history of neutropenia (WBC \<3,000/mm3).
13. Subject has coagulopathy or thrombocytopenia (platelet count \<80,000/ μL) that has not resolved or has required treatment in the past 6 months.
14. Subject has known bleeding or hypercoagulability disorder or significant anemia (Hb \< 8.0 g/dL) that cannot be corrected.
15. Subject has the following laboratory values:

    1. international normalized ratio (INR) greater than 1.5,
    2. serum creatinine level greater than 2.5 mg/dL.
