Proportion of subjects with Target Lesion Primary Patency (TLPP) at 6 Months. TLPP is defined as freedom from clinically-driven target lesion revascularization (CD-TLR) or target lesion thrombosis measured through 6 months post-procedure, which is the time interval of uninterrupted patency after study procedure to the next intervention performed on the target lesion or uncorrectable target lesion occlusion.
