Primary Outcome Measures:
  • primary Patency [ Time Frame: 12 Months ] [ Designated as safety issue: No ]
    Primary patency at 12 months, defined as absence of restenosis (≥50% stenosis) or occlusion within the originally treated lesion based on duplex ultrasound (systolic velocity ratio no greater than 2.4) and without prior TLR are defined as being primary patent at the 12-month follow-up

Secondary Outcome Measures:
  • Technical success [ Time Frame: Day 0 (=procedure date) ] [ Designated as safety issue: No ]
    Technical success, defined as the ability to cross and dilate the lesion to achieve residual angiographic stenosis no greater than 30%.

  • Hemodynamic primary patency [ Time Frame: 1 and 6 months follow-up ] [ Designated as safety issue: No ]
    Hemodynamic primary patency rate at 1 and 6-month follow-up. Patients that present without a hemodynamically significant stenosis at the target area on duplex ultrasound (systolic velocity ratio no greater than 2.4) and without prior TLR are defined as being primary patent at the given follow-up.

  • Limb-salvage rate [ Time Frame: 1, 6 and 12 months follow-up ] [ Designated as safety issue: No ]
    Limb-salvage rate at all follow-up visits, defined as absence of major amputation. Major amputation is defined as amputation at or above the ankle, as opposed to minor amputation, being an amputation at or below metatarsal level, preserving functionality of the foot).

  • Primary assisted patency rate [ Time Frame: 1, 6, 12-month follow-up ] [ Designated as safety issue: No ]
    Primary assisted patency rate at 1, 6, 12-month follow-up. Defined as flow through the treated lesion maintained by repeat percutaneous intervention completed prior to complete vessel closure.

  • Secondary patency rate [ Time Frame: 1, 6, 12-month follow-up ] [ Designated as safety issue: No ]
    Secondary patency rate at 1, 6, 12-month follow-up. Defined as flow through the treated lesion maintained by repeat percutaneous intervention after occlusion of the target lesion.

  • Target lesion revascularization [ Time Frame: 1 day, 1 month, 6 month and 12 month follow-up ] [ Designated as safety issue: No ]
    Target lesion revascularization (TLR) is defined as a repeat intervention to maintain or re-establish patency within the region of the treated arterial vessel plus 5 mm proximal and distal to the treated lesion edge.

  • Clinical success at follow-up [ Time Frame: 1 day and 1, 6, 12-month follow-up ] [ Designated as safety issue: No ]
    Clinical success at follow-up is defined as an improvement of Rutherford classification at 1 day and 1, 6, 12-month follow-up of one class or more as compared to the pre-procedure Rutherford classification.

  • Number of patients with Serious Adverse Events (SAE) as a measure of safety [ Time Frame: 1 day, 1 month, 6 month and 12 month follow-up ] [ Designated as safety issue: Yes ]
    Serious adverse events as defined as any clinical event that is fatal, life-threatening, or judged to be severe by the investigator; resulted in persistent or significant disability; necessitated surgical or percutaneous intervention; or required prolonged hospitalization
