Description
Inclusion Criteria:
- 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).
Exclusion Criteria:
- 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

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Study patients
Eligible PAD patients who are routinely treated with atherectomy by AURYON™ Atherectomy System.
|
The AURYON™ System consists of two sub-units: 1) a single use catheter ("AURYON™ catheter"); and 2) a laser system.
|
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Primary Efficacy: Acute Procedural Success
Time Frame: Peri-procedural (by the end of the index procedure)
|
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)
Time Frame: Till discharge, an average of 5 days
|
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 Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Rate of device related complications requiring intervention
Time Frame: Till discharge, an average of 5 days
|
Rate of device related complications requiring intervention, defined as peri procedural MAEs, reported by the operating physician as caused directly due to the use of the AURYON device.
|
Till discharge, an average of 5 days
|
Rates of MAEs over time
Time Frame: Post-discharge (at 30-days, 6-, 12-, and 24-months)
|
Rates of post-discharge MAEs over time; defined as: (a) Unplanned target limb amputation, (b) cardiovascular death, (c) clinically driven target lesion revascularization , (d) target vessel revascularization (TVR).
|
Post-discharge (at 30-days, 6-, 12-, and 24-months)
|
Patency rate
Time Frame: Post-discharge (at 6-, 12-, and 24-months)
|
Patency rate, defined as <50% stenosis at the treated lesion, with peak systolic velocity ratio (PSVR) of <2.5, as assessed quantitatively by Duplex ultrasonography (DUS) performed in a lab that achieved Vascular Laboratory Accreditation, at 6, 12, and 24 months.
|
Post-discharge (at 6-, 12-, and 24-months)
|
Occlusion freedom
Time Frame: Post-discharge (at 6-, 12-, and 24-months)
|
Only for BTK lesions: freedom from occlusion (100% stenosis by DUS) combined with freedom from CD-TLR
|
Post-discharge (at 6-, 12-, and 24-months)
|
Clinical outcome 1 - ankle brachial index (ABI)
Time Frame: Post-discharge (at 6-, 12-, and 24-months)
|
Change in ankle brachial index (ABI or TBI if needed) at 6, 12, and 24, months, compared to baseline. Ankle-Brachial Index (ABI) si an ankle/arm blood pressure ratio. Normal value ranges between 0.9-1.3. Under 0.9 index means blood has a difficult time getting to legs & feet; 0.4-0.9 indicates mild-moderate PAD; 0.4 and lower indicates severe PAD. Positive difference between time-points represents a clinical improvement through time and vice versa. |
Post-discharge (at 6-, 12-, and 24-months)
|
Clinical outcome 2 - walking impairment questionnaire (WIQ)
Time Frame: Post-discharge (at 6-, 12-, and 24-months)
|
Change in walking impairment questionnaire (WIQ) score at 6, 12, and 24, months, compared to baseline. WIQ is a patient fulfilled survey to grade physical ability representing PAD progress, has 3 sub-scales (walking speed, distance, climbing stairs), when the total score ranges between 0-100, higher value = better outcome. Positive difference between time-points represents a clinical improvement through time and vice versa. |
Post-discharge (at 6-, 12-, and 24-months)
|
Clinical outcome 3 - Rutherford clinical categories (RCC)
Time Frame: Post-discharge (at 6-, 12-, and 24-months)
|
Change in Rutherford clinical category at 6, 12, and 24, months, compared to baseline. Rutherford Classification is a doctor determined 7 stages scale (0= Asymptomatic, 6= Severe ischemic ulcers/frank gangrene) representing PAD progress, lower value = better outcome. Positive difference between time-points represents a clinical deterioration through time and vice versa. |
Post-discharge (at 6-, 12-, and 24-months)
|
Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Exploratory endpoint: IVUS
Time Frame: Peri-procedural (by the end of the index procedure)
|
Intravascular ultrasound assessment pre- and post-Auryon and correlation with angiographic findings (e.g.
lesion length, MLA -minimal lumen area gain, calcium severity and removal, etc.).
This endpoint will be analyzed only for cases that used IVUS as a routine practice in the index procedure.

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