PRIMARY outcome

Timeframe: 30 days

Population: This feasibility study was analyzed descriptively. While the Statistical Analysis Plan prospectively described a poolability assessment for a combined analysis cohort across the Mini-S Feasibility study and the FORWARD IDE study, no statistical significance testing was performed for the standalone Mini-S study results presented in this record. Therefore, no statistical analysis results are available for reporting in the Statistical Analysis sections of the outcome measures.

Primary patency for Above-the-Knee (ATK) lesions is defined as freedom from ≥50% restenosis as determined by DUS and freedom from CD-TLR at 12 months post-procedure. Primary patency for Below-the-Knee (BTK) lesions is defined as freedom from total occlusion (100% diameter stenosis by DUS) in all target lesions within a flow pathway and freedom from CD-TLR at 12 months post-procedure.
