Brief Summary:
This is an Outside the United States, post-CE Mark, multi-center, single-arm, non-blinded study designed to investigate the safety and efficacy of the Tack Endovascular System. This study will evaluate subjects with PAD who receive PTA (with a drug-coated balloon (DCB)) in the SFA and in popliteal arteries, ranging in diameter from 2.5mm to 6.0mm and lesion lengths of ≥20mm and ≤150mm, and have a resulting dissection(s) type(s) A through F. TOBA III will also evaluate the safety and efficacy of the device when used to treat a sub-group presenting with longer lesions of >150mm and ≤250mm.

Primary Outcome Measures :
  1. Safety - Freedom from the occurrence of any new-onset major adverse event(s) [ Time Frame: 30 days ]
    Freedom from the occurrence of any new-onset major adverse event(s) (MAEs) defined as index limb amputation (above the ankle), CEC adjudicated clinically-driven target lesion revascularization (CD-TLR), or all-cause death at 30 days.

  2. Efficacy [ Time Frame: 12 months ]
    Primary patency defined as freedom from CEC adjudicated clinically driven target lesion revascularization (CD-TLR) and freedom from core lab adjudicated duplex ultrasound derived binary restenosis at 12 months (defined as PSVR >2.5:1).
