Brief Summary

The PATHFINDER Registry is a prospective, non-randomized, single arm, multicenter observational study. This pilot registry is aimed to evaluate the performance (peri-procedural) and clinical outcomes (intermediate and long-term) of the AURYON Atherectomy System, within the initial launch phase of the product in the market.

Outcome Measures

Primary Outcomes (2)

• Primary Efficacy: Acute Procedural Success

  Percentage of lesions with successful revascularization of target vessel defined as ≤30% residual stenosis at the treated lesion post Auryon atherectomy and final adjunctive treatment (if required), as evaluated by angiographic corelab.

  Peri-procedural (by the end of the index procedure)

• Primary Safety: Freedom From Peri-procedural Major Adverse Events (PPMAE)

  Percentage of subjects with freedom from peri-procedural major adverse events (PPMAE), defined as (a) flow-limiting dissection, (b) clinically significant distal embolization, (c) bailout stenting, (d) major/unplanned amputation, (e) target vessel perforation requiring endovascular or surgical repair or (f) death, till discharge.

  Through discharge, an average of 5 days

Secondary Outcomes (7)

• Number of Participants With Device Related Complications Requiring Intervention

  Till discharge, an average of 5 days

• Number of Participants With Major Adverse Events (MAEs) Over Time

  Post-discharge (at 30-days, 6-, 12-, and 24-months)

• Number of Patent Lesions

  Post-discharge (at 6-, 12-, and 24-months)

• Freedom From Occlusion

  Post-discharge (at 6-, 12-, and 24-months)

• Change From Baseline in Ankle Brachial Index (ABI)/Tibial Brachial Index (TBI)

  Post-discharge (at 6-, 12-, and 24-months)

Study Arms (1)

Study patients

Eligible PAD patients who are routinely treated with atherectomy by AURYON Atherectomy System.

Device: AURYON Atherectomy System

Interventions

AURYON Atherectomy System DEVICE

The AURYON Atherectomy System consists of two sub-units: 1) a single use catheter ("AURYON™ catheter"); and 2) a laser system.

Study patients

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Patients with infra-inguinal PAD undergoing atherectomy with the AURYON Atherectomy System.

You may qualify if:

• Subject is ≥ 18 years old.
• Subject is a candidate for atherectomy for infra-inguinal peripheral artery disease.
• Documented symptomatic atherosclerotic peripheral artery disease with claudication or critical limb ischemia (CLI) (Rutherford Classification 2-5 ).
• Subject is capable and willing to comply with the scheduled follow up
• Subject is able and willing to sign a written Informed Consent Form (ICF).

You may not qualify if:

• Target lesion is in an arterial bypass.
• Planned use of another atherectomy device in the same procedure
• Co-morbid condition(s) with less than 1yr anticipated survival that could limit the subject's ability to participate in the trial or to comply with follow-up requirements or impact the scientific integrity of the study.
• Participating in another study on an interventional non-cleared device, that could impact the study results
