Outcomes
Primary Outcomes
Number of Participants With Freedom From Below-the-Knee (BTK) Major Adverse Limb Event and Peri-Operative Death (POD) at 30 Days Post Index Procedure.
Time Frame: 30 days post index procedure
The primary safety endpoint is defined as freedom from the composite of all-cause death, above-ankle amputation or major reintervention (new bypass graft, jump/interposition graft revision, or thrombectomy/thrombolysis) of the index limb involving a below-the-knee artery.
Number of Participants With Freedom From the Composite of Above-ankle Amputation, Target Lesion Occlusion, and Clinically-driven Target Lesion Revascularization at 6 Months Post Index Procedure.
Time Frame: 6 months post-index procedure
The primary efficacy endpoint is defined as freedom from the composite of above-ankle amputation, target lesion occlusion, and clinically-driven target lesion revascularization. All amputations included in endpoints refer to amputations in the index limb.
