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 - Primary Patency [ 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).

    8. Eligible for standard surgical repair, if necessary
    9. Subject is ambulatory (assistive devices such as a cane or walker is acceptable

Exclusion Criteria:

  • Subject must NOT meet any of the following exclusion criteria to be eligible for enrollment:

    1. Rutherford Classification 0, 1, 5 or 6
    2. Is pregnant or refuses to use contraception through the duration of the study
    3. Previous infrainguinal bypass graft in the target limb
    4. Planned amputation on the target limb
    5. Systemic infection or infection within the target limb and/or immunocompromised
    6. Endovascular or surgical procedure (not including diagnostic procedures) on the target limb within 30 days prior to or within 30 days after the index procedure
    7. Endovascular or surgical procedure (not including diagnostic procedures) on the non-target limb within 14 days prior to the index procedure or planned procedure within 30 days after the index procedure
    8. Prior coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI) procedure within 30 days prior to the index procedure or planned CABG/PCI within 30 days after the index procedure
    9. Any other previous or planned surgical or endovascular procedure (not including diagnostic procedures) within 14 days prior to or 30 days post index procedure
    10. Planned atherectomy, cryoplasty, stenting or any other treatment (with the exception of a crossing device) of the target lesion other than PTA during the index procedure
    11. Known coagulopathy, hypercoagulable state, bleeding diathesis, other blood disorder, or a platelet count less than 80,000/microliter or greater than 500,000/microliter
    12. Known hypersensitivity or allergy to antiplatelet or anticoagulant therapy

    17. Known hypersensitivity or contraindication to nickel-titanium alloy (Nitinol)
    18. Participating in another ongoing investigational clinical trial that has not completed its primary endpoint
    19. Has other comorbidities that, in the opinion of the investigator, would preclude them from receiving this treatment and/or participating in study-required follow-up assessments
    20. Known hypersensitivity or allergy to contrast agents that cannot be medically managed
    21. Thrombolysis of the target vessel within 72 hours prior to the index procedure, where complete resolution of the thrombus was not achieved
