Inclusion Criteria:

  1. Subject is ≥ 18 and ≤ 80 years of age at the time of signing informed consent.

    For subjects with bilateral lesions, the higher Rutherford-Becker Clinical Category limb will be considered the target extremity to be treated in this trial.

    If both limbs are of the same Rutherford Becker Clinical Category, the target extremity will be selected based on investigator discretion.

  3. Subject or legally authorized representative has been informed of the nature of the study, agrees to its provisions, and is able to provide informed consent.
  4. Subject agrees to undergo all protocol-required follow-up examinations and requirements at the investigational site.

  8. Subject must agree not to participate in any other clinical investigation for a period of 12 months following the index procedure. This includes clinical trials of medications and invasive procedures. Questionnaire-based studies, or other studies that are non-invasive and do not require medication are allowed.

Ankle Brachial Index (ABI) for the Treated Limb
Time Frame: At 1 month

The ABI is the ratio of the ankle to arm pressure, and it is calculated by dividing the systolic blood pressure in the ankle of the one leg by the higher of the two systolic blood pressures in the arms.

An ABI of 0.9 - 1.3 is a normal range. A reduced ABI (less than 0.9) is consistent with peripheral artery occlusive disease, with values below 0.8 indicating moderate disease and below 0.5 indicates severe disease. A value greater than 1.3 is considered abnormal suggesting calcification of the walls of the arteries and noncompressible vessels, reflecting severe peripheral vascular disease. Subjects with ABI values greater than 1.3 will be excluded from the analysis.

Calculation of the Ankle Brachial Index:

(Highest Ankle Systolic Pressure/Highest Brachial Systolic Pressure = ABI)

Walking Impairment Questionnaire (WIQ) Scores
Time Frame: At 1 month

Measured by the Walking Impairment Questionnaire (WIQ), a disease-specific instrument utilized to characterize walking ability through a questionnaire as an alternative to treadmill testing. It is a measure of subject-perceived walking performance for subjects with Peripheral Artery Disease (PAD) and/or intermittent claudication.

The WIQ quantifies patient-reported walking speed, walking distance, and stair-climbing ability, respectively, on a scale of 0 (= worst) to 100 (= best).

SF-12® Health Survey is validated measure using 12 questions to measure functional health and well-being from the patient's point of view. Scores on the scale are 0% (indicating poor perceived health status) to 100% (indicating excellent perceived health status) possible.

Vascular Quality of Life (VascuQol) Scores Summary
Time Frame: At 1 month

Vascular Quality of Life Questionnaire is defined as a disease specific quality of life (QOL) measure for subjects with chronic lower limb ischemia. Each item is rated as a seven point response scale, with a score of one being the worst and a score of seven the best possible. The total average score is the sum of all 25 items scores divided by 25. For each separate domain an average score can be calculated (sum of all items of one domain divided by the number of items of that domain). The highest score for each domain is 7, which indicates best health outcome.

The domains include Activity Domain, Symptom Domain, Pain Domain, Emotional Domain, Social Domain.
