Measure
Bare Temporary Spur Stent System
n=130 Participants
Treatment with the Temporary Bare Spur Stent System (Spur Stent System). Bare Temporary Spur Stent System: Treatment of qualifying infrapopliteal arteries with the Bare Temporary Spur Stent System, in subjects with critical limb ischemia.
Primary Efficacy Endpoint: Percentage of Participants With Technical Success of the Bare Temporary Spur Stent
99.2 percentage of participants

PRIMARY outcome

Timeframe: 30 days post procedure

Number of participants with freedom from the occurrence of major adverse limb events (MALE) \[evaluated at 30 days post procedure\] and peri-operative death (POD) \[defined as all-cause mortality within 30 days post procedure\]. MALE is defined as: * Above-the-ankle amputation of the index limb * Major reintervention (new bypass graft, jump/interposition graft revision, or thrombectomy/thrombolysis) of the index limb involving the infrapopliteal arteries.
