  16. Sudden symptom onset, acute vessel occlusion, or acute or sub-acute thrombus in target vessel;
  17. Severe calcification that renders the lesion un-dilatable;

Outcomes

Primary Outcome Measures

Number of Participants With Unanticipated Device- or Drug-Related Serious Adverse Events at 60 Months Post Index Procedure.

Secondary Outcome Measures

Number of Subjects With Freedom From Death, Index-Limb Amputation, and Target Vessel Revascularization (TVR) at 30 Days Post Index Procedure
Number of subjects with Freedom from all-cause death, index limb amputation above the ankle and Target Vessel Revascularization (TVR) (VIVA Safety Endpoint)
Number of Participants With All-Cause Perioperative (<30 Day) Death, Index Limb Amputation, Index Limb Re-intervention, and Index Limb Related Death at 1,6, 12, 24, 36, 48, and 60 Months Post Index Procedure
Percentage of Participants With Primary Patency of the Target Lesion at 6, 12, and 24 Months Post Index Procedure
Primary Patency is defined as the absence of target lesion restenosis (defined by DUS peak systolic velocity ratio (PSVR) ≥2.5) and freedom from target lesion revascularization (TLR).
Number of Acute Device Success at Time of Index Procedure
Device Success was defined as the achievement of successful delivery and deployment of the study device(s) as intended at the intended target lesion, without balloon rupture or inflation/deflation abnormalities and a successful withdrawal of the study system.
Number of Participants With Technical and Procedural Success
Technical Success is defined as successful access and deployment of the device and visual estimate of ≤30% diameter residual stenosis during the index procedure without deployment of a bailout stent. Procedural Success is defined as attainment of ≤30% residual stenosis in the treatment area by independent core lab analysis without serious adverse events during the index procedure.
Number of Participants With Freedom From Target Lesion Revascularization (TLR) at 6, 12, and 24 Months Post Index Procedure
Number of Participants With Alternative Primary Patency at 6, 12, and 24 Months Post Index Procedure
Percentage of subjects with Alternative Primary Patency based on alternative definitions of duplex ultrasound (DUS) peak systolic velocity ratio (PSVR) <2.0 and <3.0 at 6, 12, and 24 months post index procedure. DUS PSVR was calculated by dividing the maximum peak systolic velocity (PSV) from the stenosis by the PSV from the nearest segment of normal artery above the site of increase.
Improvement in Rutherford Classification Scores at 6, 12, and 24 Months Post Index Procedure Compared to Baseline
The endpoint summarizes the change in index-limb Rutherford Classification of participants from baseline through 24 months. Data is presented as shift from baseline Rutherford Classification data using the following categories: 1) Improvement, 2) Same, and 3) Worsened.
Change in Resting Ankle Brachial Index (ABI) at 6, 12, and 24 Months Compared to Baseline
Mean change from baseline values. The Ankle Brachial Index (ABI) is defined as a ratio of ankle to brachial (upper arm) artery systolic blood pressure and aims at determining how well the blood is flowing in the legs.
