Brief Summary:
A single-arm study to assess the utility of the Pantheris SV catheter in addressing peripheral artery disease in arteries located below the knee. Data will be collected on the percent stenosis pre- and post-atherectomy and then symptoms and adverse events noted at 30 days, 6 months, and 1 year after the procedure.

Condition or disease Intervention/treatment Phase
Peripheral Arterial Disease Device: Atherectomy Not Applicable

Detailed Description:
This is a post-market, single-arm study of the optical coherence tomography (OCT)-guided directional atherectomy catheter, Pantheris SV. Patients presenting with reduced blood flow in the lower extremity arteries will under directional atherectomy, followed by adjunctive therapy as deemed necessary by the physician, and then adverse events and symptom resolution will be documented at 30 days, 6 months, and 1 year after the procedure. Primary safety endpoints are related to adverse events and will be assessed at the time of the procedure and at 30 days after the procedure. Effectiveness endpoints center on restoration of blood flow.

Arm Intervention/treatment
Single Arm
Single-arm study
Device: Atherectomy
Directional atherectomy of lesions below the knee.

Primary Outcome Measures :
  1. Major Adverse Events [ Time Frame: from procedure to 30 days post-procedure ]
    freedom from cardiovascular-related events

  2. Technical success [ Time Frame: At 1 day post-procedure ]
    defined as residual stenosis < 50 percent after atherectomy

Secondary Outcome Measures :
  1. Procedure success [ Time Frame: At 1 day post-procedure ]
    defined as residual stenosis < 30 percent post adjunctive therapy

  2. Freedom from target vessel revascularization (TVR) [ Time Frame: At 6 and 12 months post-procedure ]
    revascularization needed further

  3. Primary patency [ Time Frame: At 6 and 12 months post-procedure ]
    change in peak systolic velocity ratio (PSVR)

  4. Ankle-Brachial Index (ABI) [ Time Frame: At 6 and 12 months post-procedure ]
    change since index procedure

  5. Rutherford Classificaiton [ Time Frame: At 30 days, 6 months, and 1 year post-procedure ]
    Change since index procedure
