Primary Outcome Measures

Name	Time	Method
Composite of Major Adverse Events (MAEs)	30 days	Percentage of study subjects experiencing a major adverse event (MAE) defined as: * Device- or procedure-related death within 30 days of the index procedure; and * Myocardial Infarction (MI) occurring within 30 days of the index procedure; and * Amputation above the metatarsals in the treated leg, resulting from a vascular event, occurring within 30 days of the index procedure.

Secondary Outcome Measures

Name	Time	Method
Change in Functional Status - EQ5D - Usual Activities	6 Months	Change in functional status (EQ5D - Usual Activities) from pre-procedure at 6 months. EQ5D is a standard instrument for use as a measure of health outcome.
Freedom From Target Lesion(s) Revascularization (TLR)	6 Months	Kaplan-Meier estimate of freedom from target lesion revascularization (TLR) at 6 months. TLR is defined as revascularization occurring within the treated segment(s) by means of a percutaneous vascular intervention, surgical bypass, thrombolysis, or other invasive means.
Number of Participants With Change in Rutherford Category	6 Months	Change in Rutherford Category from pre-procedure at 6 months. Rutherford categories include: Stage 0 - Asymptomatic Stage 1 - Mild claudication Stage 2 - Moderate claudication - The distance that delineates mild, moderate and severe claudication is not specified in the Rutherford classification, but is mentioned in the Fontaine classification as 200 meters. Stage 3 - Severe claudication Stage 4 - Rest pain Stage 5 - Ischemic ulceration not exceeding ulcer of the digits of the foot Stage 6 - Severe ischemic ulcers or frank gangrene
Secondary Patency	6 Months	Kaplan-Meier estimate of secondary patency at 6 months. Secondary patency is defined as presence of blood flow, with or without reintervention, in the originally treated segment(s), including the proximal and distal margins.
Change in Functional Status - EQ5D - Self Care	6 Months	Change in functional status (EQ5D - Self Care) from pre-procedure at 6 months. EQ5D is a standard instrument for use as a measure of health outcome.
Acute Procedural Success	Discharge	Number of subjects who experience acute procedural success defined as less than or equal to 30% residual stenosis prior to procedure completion and no device- or procedure-related SAEs before discharge at day 1.
Thirty-day Clinical Success	30 Days	Number of subjects who experienced 30-day clinical success defined as an improvement of at least one Rutherford Category at the 30-day visit as compared to pre-procedure and no device- or procedure-related serious adverse events (SAEs) within 30 days of the index procedure. Rutherford categories include: Stage 0 - Asymptomatic Stage 1 - Mild claudication Stage 2 - Moderate claudication - The distance that delineates mild, moderate and severe claudication is not specified in the Rutherford classification, but is mentioned in the Fontaine classification as 200 meters. Stage 3 - Severe claudication Stage 4 - Rest pain Stage 5 - Ischemic ulceration not exceeding ulcer of the digits of the foot Stage 6 - Severe ischemic ulcers or frank gangrene
Primary Patency	6 Months	Kaplan-Meier estimate of primary patency at 6 months. Primary patency is defined as blood flow in the treated segment(s), without reintervention.
Freedom From Target Vessel Revascularization (TVR)	6 Months	Kaplan-Meier estimate of freedom from target vessel revascularization (TVR) at 6 months. TVR is defined as revascularization of the vessel treated at the time of the index procedure by means of a percutaneous vascular intervention, surgical bypass, thrombolysis, or other invasive means.
Change in Functional Status - EQ5D- Mobility	6 Months	Change in functional status (EQ5D - Mobility) from pre-procedure at 6 months. EQ5D is a standard instrument for use as a measure of health outcome.

Number of Participants With a Change in Rutherford Category	30 Days	Change in Rutherford Category from pre-procedure at 30 days. Rutherford categories include: Stage 0 - Asymptomatic Stage 1 - Mild claudication Stage 2 - Moderate claudication - The distance that delineates mild, moderate and severe claudication is not specified in the Rutherford classification, but is mentioned in the Fontaine classification as 200 meters.

Freedom From Major Adverse Events (MAEs)	6 months	Number of subjects experiencing freedom from procedure- or device-related events causing death, occurring within 30 days of the index procedure; and myocardial infarction (MI) occurring within 30 days of the index procedure; and target lesion revascularization (TLR) occurring within 6 months of the index procedure; and major amputation of the treated leg(s), resulting from a vascular event, occurring within 6 months of the index procedure.
Change in Functional Status - EQ5D - Anxiety/Depression	6 Months	Change in functional status (EQ5D - Anxiety/Depression) from pre-procedure at 6 months. EQ5D is a standard instrument for use as a measure of health outcome.
Change in Ankle Brachial Index (ABI)	6 Months	Change in Ankle Brachial Index(ABI) from pre-procedure at 6 months. Larger values indicate a better outcome.The ABI is the systolic pressure at the ankle, divided by the systolic pressure at the arm
Change in Functional Status - EQ5D - Pain/Discomfort	6 Months	Change in functional status (EQ5D - Pain/Discomfort) from pre-procedure at 6 months. EQ5D is a standard instrument for use as a measure of health outcome.
