The Merit WRAPSODY™ Endovascular Stent Graft for Treatment of Iliac Artery Occlusive Disease

Study Description
Brief Summary:
This is a prospective, single-center, non-randomized phase 2, first-in-iliac artery study, to evaluate the safety and effectiveness of the WRAPSODY Stent Graft for the treatment of peripheral arterial occlusive disease in symptomatic subjects with de novo or restenotic lesions in the common iliac artery (CIA) and/or external iliac artery (EIA), including lesions at the aortic bifurcation.

Condition or disease Intervention/treatment Phase
Stenosis of Artery Peripheral Arterial Disease Iliac Artery Disease Iliac Artery Occlusion Device: Placement of WRAPSODY stent graft Not Applicable

Detailed Description:

Approximately 30 subjects will be enrolled. Post study procedure subjects will have planned follow-up visits at 4 weeks, 24, 36 and 52 weeks, and unscheduled visits as medically necessary,

The primary study safety endpoint is the proportion of subjects free from a composite of device- or procedure-related death, myocardial infarction, or amputation above the metatarsals in the treated leg resulting from a vascular event, or device- or procedure-related serious adverse events within 4 weeks of the index procedure. The primary clinical effectiveness endpoint is the proportion of subjects with a composite improvement of at least 1 Rutherford category and patency as evaluated by duplex ultrasound at 4 weeks after index procedure.

  20. Abdominal aortic artery stent, if it could interfere with placement of the study device
  21. Target lesion(s) are located such that the stent graft would prevent blood flow to the internal iliac artery, if patent
  22. Lesions requiring atherectomy or ablation to facilitate stent graft delivery
  23. Any other condition deemed exclusionary in the opinion of the investigator for documented reasons relating to the health and/or welfare of the subject
