|---|---|
|
Study patients
Eligible PAD patients who are routinely treated with atherectomy by AURYON Atherectomy System.
|
The AURYON Atherectomy System consists of two sub-units: 1) a single use catheter ("AURYON™ catheter"); and 2) a laser system.

主要结果指标
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
Primary Efficacy: Acute Procedural Success
大体时间:Peri-procedural (by the end of the index procedure)
|
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)
大体时间:Through 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.

Through discharge, an average of 5 days

大体时间 |
|---|---|---|
|
Number of Participants With Device Related Complications Requiring Intervention
大体时间:Till discharge, an average of 5 days
|
Number of participants with device related complications requiring intervention, defined as peri procedural Major Adverse Events (MAEs), reported by the operating physician as caused directly due to the use of the AURYON device.
|
Till discharge, an average of 5 days
|
|
Number of Participants With Major Adverse Events (MAEs) Over Time
大体时间:Post-discharge (at 30-days, 6-, 12-, and 24-months)
|
Number of participants with 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)
|
|
Number of Patent Lesions
大体时间:Post-discharge (at 6-, 12-, and 24-months)
|
Number of patent lesions, defined as <50% stenosis at the treated lesion, with peak systolic velocity ratio (PSVR) of <2.5, as assessed quantitatively by Duplex ultrasonography (DUS), at 6, 12, and 24 months.
|
Post-discharge (at 6-, 12-, and 24-months)
|
|
Freedom From Occlusion
大体时间:Post-discharge (at 6-, 12-, and 24-months)
|
Number of below-the-knee (BTK) lesions with freedom from occlusion (100% stenosis by DUS) combined with freedom from clinically-driven target lesion revascularization (CD-TLR)
|
Post-discharge (at 6-, 12-, and 24-months)
|
|
Change From Baseline in Ankle Brachial Index (ABI)/Tibial Brachial Index (TBI)
大体时间:Post-discharge (at 6-, 12-, and 24-months)
|
Change in ankle brachial index (ABI) or tibial brachial index (TBI) if ABI unavailable at 6, 12, and 24, months, compared to baseline. Ankle-Brachial Index (ABI) is 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 and feet; 0.4-0.9 indicates mild-moderate peripheral artery disease (PAD); 0.4 and lower indicates severe PAD. Positive change between timepoints represents a clinical improvement over time. |
Post-discharge (at 6-, 12-, and 24-months)
|
|
Change From Baseline in Walking Impairment Questionnaire (WIQ)
大体时间: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 reported outcome (survey) to grade physical ability representing PAD progress. It has 3 sub-scales (walking speed, distance, climbing stairs), with the total score ranging between 0-100. A higher score means less impairment; positive change between timepoints represents a clinical improvement through time. |
Post-discharge (at 6-, 12-, and 24-months)
|
|
Change From Baseline in Rutherford Clinical Category (RCC)
大体时间:Post-discharge (at 6-, 12-, and 24-months)
|
Change in Rutherford Clinical Category at 6, 12, and 24, months, compared to baseline. Rutherford Category is a physician-assessed measurement, with 7 stages (0= Asymptomatic to 6= Severe ischemic ulcers/frank gangrene) representing PAD progress. Lower value means less impairment. Positive difference between timepoints represents a clinical deterioration over time. |
Post-discharge (at 6-, 12-, and 24-months)
