Brief Summary

The PATHFINDER I Registry is a prospective, non-randomized, single arm, multicenter observational study. It is a pilot registry study towards a subsequent large pivotal phase registry. 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 subjects with successful revascularization of target vessel defined as ≤30% residual stenosis at the index 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.

    Till discharge, an average of 5 days

Secondary Outcomes (7)

  • Rate of device related complications requiring intervention

    Till discharge, an average of 5 days

  • Rates of MAEs over time

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

  • Patency rate

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

  • Occlusion freedom

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

  • Clinical outcome 1 - ankle brachial index (ABI)

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

  • +2 more secondary outcomes

Other Outcomes (1)

  • Exploratory endpoint: IVUS

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

Study Arms (1)

Study patients

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

Device: AURYON™ System

Interventions

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

Study patients

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-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
