Primary Outcome Measures :
  1. Target limb salvage rate [ Time Frame: 1-Month Post Procedure ]

Secondary Outcome Measures :
  1. Technical Success [ Time Frame: Immediate Post Procedure ]

    Defined as TIMI 2/3 flow rate

    TIMI flow grading range 1-3, with higher grading representing better outcome

  2. Modified SVS runoff score [ Time Frame: Immediate Post Procedure ]

    Immediate Post Procedure as compared to Baseline

    Modified SVS runoff score ranges from 0-19, with a higher score indicating more severe disease

  3. Improvement of Rutherford classification [ Time Frame: Up until study completion, at approximately 12-Months ]

    Improvement of one or more as compared to pre-procedure

    Rutherford classification ranges from I-III, with a higher score representing worse outcomes

  4. Vessel Patency [ Time Frame: 1-Month Post-Procedure ]
  5. Target limb salvage rate [ Time Frame: 12-Months Post Procedure ]
  6. Rates of device related serious adverse events (SAEs) [ Time Frame: Up until study completion, at approximately 12-Months ]
  7. Major bleeding peri-procedure [ Time Frame: During procedure ]
  8. Mortality [ Time Frame: 12-Months ]
