Subject has been diagnosed with chronic renal failure or has a creatinine level \> 2.5, unless on dialysis, prior to the index treatment. 8. Subject has evidence of intracranial or gastrointestinal bleeding within 90 days. 9. Subject has a history of trauma, fracture, major surgery (includes major amputation), or biopsy of a parenchymal organ within past 14 days, or patient has not healed from a previous medical intervention occurring more than 14 days. 10. Subject has a history of stroke or myocardial infarction (MI) within 90 days prior to enrollment in the study. 11.

Subject has a planned interventional treatment to address stenosis of the contralateral limb scheduled within 60 days after the index treatment. 13. Subject has a planned interventional treatment to address inflow stenosis of the ipsilateral limb scheduled within 60 days after the index treatment. 14. Inflow or bilateral PAD requiring treatment prior to enrollment was not successfully treated, defined as \> 50% residual stenosis and/or occurrence of procedural angiographic complications, excluding dissection types A and B. 15. Subject has previously had their other limb treated as part of the study. Angiographic Inclusion Criteria: 1. Target lesion(s) located in the anterior tibial (AT), posterior tibial (PT), tibial peroneal trunk (TPT) or peroneal (PR) arteries. 2. Target lesion has ≥ 50 % stenosis by angiography. 3. Subject has a corresponding wound being fed by the target vessel. Angiographic Exclusion Criteria: 1.

Target lesion is within a bypass graft or near a previously placed stent. 4. The guide wire cannot be passed across the target lesion. 5. Anterograde access of the lesion is not possible. 6. Subject has angiographic evidence of significant dissection at or near the treatment site. 7. Interventional treatment is intended for in-stent restenosis at the peripheral vascular site. 8. Subject's wound(s) involve multiple angiosomes.
