Brief Summary:
The objective of this prospective, multicenter, randomized, controlled clinical trial is to demonstrate the superiority of the VBX Device for primary patency when compared to bare metal stenting in complex iliac occlusive disease.

Primary Outcome Measures :
  1. Primary Patency [ Time Frame: 1 year ]
    Blood flow through the target lesion (no evidence of binary restenosis >50% or occlusion) without a Target Lesion Revascularization (TLR).


Secondary Outcome Measures :
  1. Technical success [ Time Frame: at the procedure ]
    Deployment of device with < 30% residual stenosis on final angiography.

  2. Acute procedural success [ Time Frame: at the procedure ]
    Binary assessment based on technical success and freedom from device or procedure-related serious adverse events (SAE) requiring intervention.

  3. Clinical success [ Time Frame: Through 1 month ]
    Improvement from baseline of at least 1 Rutherford Category and freedom from device or procedure-related SAE requiring intervention.

  4. Hemodynamic Status [ Time Frame: Through 5 years ]
    Change in Ankle-brachial index (ABI)/toe-brachial index (TBI) as compared to baseline

  5. Change in EQ-5D-5L [ Time Frame: Through 5 years ]
    Change in EQ-5D-5L responses as compared to baseline. The EQ-5D-5L Questionnaire measures quality of life (QoL) over 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is measured over five levels from no problems to extreme problems. Scored on a 0 to 100 scale with 0 as the worst possible health and 100 is the best possible health.

  6. Change in WIQ [ Time Frame: Through 5 years ]
    Change in Walking Impairment Questionnaire (WIQ) responses as compared to baseline. The WIQ is a validated QoL measurement of walking abilities over 3 dimensions: distance, speed, and stair-climbing. Scored on a 0 to 100 scale with 0 as no degree of difficulty and 100 is the highest degree of difficulty.

  7. Primary patency [ Time Frame: Through 5 years ]
    Blood flow through the target lesion (no evidence of binary restenosis >50% or occlusion) without a Target Lesion Revascularization (TLR).

  8. Freedom from binary restenosis [ Time Frame: Through 5 years ]
    Freedom from binary restenosis. binary restenosis defined as evidence of >50% restenosis or occlusion of the target lesion(s) based on core lab adjudicated duplex ultrasound or angiography

  9. Primary assisted patency [ Time Frame: Through 5 years ]
    Blood flow maintained (no evidence of occlusion) through the target lesion with or without a Target Lesion Revascularization (TLR).

  10. Secondary patency [ Time Frame: Through 5 years ]
    Blood flow through the target lesion with or without a Target Lesion Revascularization (TLR).

  11. Freedom from target lesion revascularization [ Time Frame: Through 5 years ]
    Freedom from target lesion revascularization (TLR). TLR defined as endovascular or surgical intervention performed on the target lesion(s).

  12. Cumulative reintervention rate [ Time Frame: Through 5 years ]
    Rate of first and recurrent Target Lesion Revascularization (TLR).

  13. Freedom from clinically driven target lesion revascularization [ Time Frame: Through 5 years ]
    Freedom from clinically driven target lesion revascularization. Endovascular or surgical intervention performed on the target lesion(s) in response to recurrent symptoms (increase ≥ 1 Rutherford Category).

  14. Amputation-free survival [ Time Frame: Through 5 years ]
    Binary assessment based on freedom from major amputation (target limb, amputation above the metatarsals) and all-cause mortality

  15. Survival [ Time Frame: Through 5 years ]
    Freedom from all-cause mortality

  16. Change in Rutherford Category [ Time Frame: Through 5 years ]
    Change in Rutherford Category as compared to baseline. Scaled from 0 to 6, with 0 as asymptotic and 6 as major tissue loss, extending above the transmetatarsal (TM) level, functional foot no longer salvageable.
