Experimental: BioMimics 3D Stent
Implantation of BioMimics 3D nitinol stent using the BioMimics 3D Stent System
Device: BioMimics 3D Stent System
- Primary Safety Endpoint (Freedom From a Composite of Major Adverse Events (MAE) [ Time Frame: 30 days ]Freedom from a composite of major adverse events (MAE) comprising death, any major amputation performed on the target limb or clinically-driven target lesion revascularization (TLR) through 30 days.
- Primary Effectiveness Endpoint (Primary Stent Patency Rate) [ Time Frame: 12 months ]Primary stent patency rate at 12 months.
- Secondary Safety (Overall MAE Rate at 30 Days) [ Time Frame: 30 Days ]Contribution of individual MAE rates for death, major amputation performed on the target limb and clinically-driven target lesion revascularization to the overall MAE rate at 30 days.
- Long Term Safety (Overall MAE Rate at Month 12) [ Time Frame: 12 months ]Overall MAE rate at Month 12 and contribution of individual event rates to the overall MAE.
- Long Term Safety (Overall Rate and Incidence of Type of Serious Adverse Events) [ Time Frame: 36 Months ]Overall rate and incidence of type of serious adverse events from Day 0 through completion of Study follow-up at Month 36.
- Technical Success [ Time Frame: Procedural (at end of index procedure) ]Percentage of subjects in which a final result of ≤50% residual diameter stenosis (in-stent) was achieved at index procedure
- Primary Stent Patency [ Time Frame: Months 12 & 24 ]Determined at Months-12 and 24 using values of: PSVR >2.0, >2.4; >2.5; and >3.5, each to indicate loss of patency on duplex ultrasound or where angiography reveals >50% diameter stenosis or where the subject undergoes clinically-driven TLR.
- Clinical Outcome (Rutherford Clinical Category) [ Time Frame: Baseline, Day 30, Months 12 & 24 ]Comparison of Rutherford Clinical Category measured at Baseline, Day 30, Months 12 and 24.
- Clinical Outcome (Six-Minute Walk Test) [ Time Frame: Baseline, Day 30, Months 12 & 24 ]Comparison of measured at Baseline, Day 30, Months 12 and 24 (subgroup of US investigational sites only).
- Functional Outcome (Ankle Brachial Index (ABI) Measurement) [ Time Frame: Day 30, Months 12 & 24 ]Comparison of the ankle brachial index (ABI) measurement at Baseline, within 30 days after index procedure, then at Months 12 and 24.
- Functional Outcome (Walking Impairment Questionnaire) [ Time Frame: Baseline, Day 30, Months 12 & 24 ]Comparison of the Walking Impairment Questionnaire at Baseline, within 30 days after index procedure, then at Months 12 and 24.
- Stent Integrity (Measured as Freedom From Stent Fracture) [ Time Frame: Months 12, 24 & 36 ]Stent integrity measured as freedom from stent fracture.
