- Primary Outcome Measures
Name Time Method Freedom from the composite Major Adverse Event rate, defined as periprocedural related death, amputation of the target limb, and clinically driven TLR assessed at 9 months post-procedure. 9 months post-procedure
- Secondary Outcome Measures
Name Time Method Evaluation of all AEs pre-discharge through 24 months post-procedure Major Adverse Event rate at 30 days, and 12- and 24- months post-procedure defined as a composite of peri-procedural related death, amputation of the target limb, and clinically driven TLR. 30 days, 12- and 24- months post-procedure Primary stent patency at 9 months defined by a binary duplex ultrasound peak systolic velocity ratio ≤ 2.4 at the stented target lesion and absence of TLR. 9 months post-procedure Technical Success defined by the following conditions: 1) Successful delivery of the stent at the lesion site 2) Stent(s) successfully deployed in lesion with adequate lesion coverage The outcome is assessed up to 24 hours from time of enrollment through index procedure. Technical success will be evaluated from time of enrollment through index procedure
Procedural Success: Attainment of < 30% residual stenosis of the target lesion and no peri-procedural complications. The outcome is assessed up to 24 hours from time of enrollment through index procedure Procedural success will be evaluated from time of enrollment through index procedure. Peri-procedural complications defined as: death, stroke, myocardial infarction (MI), emergent surgical revascularization, significant distal embolization in target limb, and thrombosis of target vessel.
Clinical Success: Relief or improvement (without increase of one or more in the score) from baseline symptoms as measured by the Rutherford score for chronic limb ischemia at 30 days as compared to baseline. 30 days post-procedure Clinical success will be evaluated from time of enrollment through index procedure. In addition, evaluation of Rutherford sustained (without increase of one or more in the score) at 9 months post-procedure from 30 days post-procedure for durability of results.
Ankle Brachial Index (ABI) change from baseline through 9 months post-procedure Clinically driven Target Vessel Revascularization (TVR) at 30 days and 9, 12- and 24- months post-procedure 30 days and 9, 12 and 24 months post-procedure TVR is defined as any re-intervention or artery bypass surgery involving the target vessel in which the subject has ≥ 50% diameter stenosis with worsening symptoms, or ≥ 70% stenosis without symptoms. The target vessel is defined as the vessel containing the treated lesion (e.g., common and/or external iliac artery).
Clinically driven TLR through 30 days and 9-, 12- and 24-months post-procedure. 30 days and 9-, 12- and 24-months post-procedure Clinically driven TLR is defined as re-intervention of the target lesion in which subject has ≥ 50% stenosis with worsening symptoms, or ≥ 70% stenosis without symptoms
Walking Impairment Questionnaire change from baseline (pre-procedure) at 30 days and 9 months post procedure Evaluation of access site complications including severe bleeding, hematoma, and pseudoaneurysm, occurring prior to hospital discharge. The event is assessed from time of enrollment through hospital discharge or up to 7 days post procedure, whichever occurs first Occurrence of device deficiency through 24 months post-procedure A device deficiency has occurred when there is inadequacy of a medical device with respect to its identity, quality, durability, reliability, usability, safety or performance. Device deficiencies include malfunctions, use errors, and inadequacy in the information supplied by the manufacturer including labelling
Device Related Complications 9 months post-procedure
