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.

Arm Intervention/treatment
Experimental: Group Treated with stent graft
This is a single arm study. All subjects will be treated with the WRAPSODY stent graft.
Device: Placement of WRAPSODY stent graft
Placement of WRAPSODY stent graft into the iliac arteries and/or aortic bifurcation.




Primary Outcome Measures :
  1. Safety endpoint of subjects free from specified adverse events [ Time Frame: 4 weeks after placement of WRAPSODY stent graft ]
    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.

  2. Effectiveness endpoint of subjects with improvement of Rutherford Category [ Time Frame: 4 weeks after placement of WRAPSODY stent graft ]
    The primary clinical effectiveness endpoint is the proportion of subjects with improvement of at least 1 Rutherford category within 4 weeks of the index procedure. Composite with Outcome 3.

  3. Effectiveness endpoint of subjects with patency [ Time Frame: 4 weeks after placement of WRAPSODY stent graft ]
    The primary clinical effectiveness endpoint is the proportion of subjects with patency as evaluated by duplex ultrasound at 4 weeks after index procedure. Composite with Outcome 2.

  5. Symptomatic claudication or rest pain without tissue loss, Rutherford category 2-4
  6. Angiographic evidence of de novo or restenotic target lesion(s) in native vessels in the common and/or external iliac artery(ies) (multiple stenoses may exist within the target lesion)

  11. Adequate ipsilateral blood flow, including at least 1 patent (<50% stenotic) superficial femoral or profundal femoral artery
  12. Full expansion of an appropriately sized (in the investigator's opinion) standard angioplasty balloon has been achieved during primary angioplasty at the target lesion prior to enrollment

Exclusion Criteria:

  1. Subject has undergone an intervention (surgical or percutaneous) in the target limb(s) <30 days from the date of the index study procedure
  2. Subject has a surgical or percutaneous procedure in the target limb(s) planned within 30 days following the index study procedure
  3. Previous or planned bypass surgery in the target limb(s)
  4. Coronary intervention within 30 days prior to enrollment or planned within 12 months after index study procedure

  6. Subject has had a transient ischemic attack within 30 days prior to the index study procedure
  7. Uncorrectable coagulation disorder
  8. Subject cannot receive heparin, dual antiplatelet treatment, or anticoagulant(s) appropriate in the opinion of the investigator
  9. Condition unrelated to study anticipated to require indefinite anticoagulation
  10. Evidence of blood borne infection
  11. Hypersensitivity to nickel titanium alloy
  12. Allergy to radiographic contrast material which cannot be adequately premedicated
