PREVEIL is a prospective, multi-center, single-arm clinical trial to assess the safety and functionality of the SurModics drug coated balloon (DCB) in the treatment of subjects with symptomatic peripheral artery disease (PAD) due to de novo stenoses of the femoral and popliteal arteries. The trial will enroll up to 15 subjects.
PREVEIL will enroll patients presenting with angiographic evidence of significant stenosis in the femoral or popliteal arteries. All enrolled subjects will be treated with the SurVeil DCB.

Peak paclitaxel plasma concentration
Paclitaxel plasma levels will be assessed at baseline, immediately post-index procedure, at 1h, 2h, 4h, 12h (or upon discharge), and 30 days post-index procedure.
Time frame: Up to 30 days
Area under the drug concentration time curve
Area under the drug concentration time curve from the time of intervention to the time where the paclitaxel level is no longer quantifiable will be measured. Paclitaxel plasma levels will be assessed at baseline, immediately post-index procedure, at 1h, 2h, 4h, 12h(or upon discharge), and 30 days post-index procedure.
Time frame: Up to 30 days
Technical success
Technical success, defined as successful delivery, inflation, deflation and retrieval of the intact study balloon device.
Time frame: At procedure
Device success
Device success, defined as achievement of \< 50% residual stenosis of the target lesion (by core lab assessed quantitative angiography (QA)) using only the study device.
Time frame: At procedure
Procedure success
Procedure success, defined as achievement of \< 50% residual stenosis of the target lesion (by core lab assessed QA) using the study device with or without the use of additional devices, without the occurrence of death, amputation or repeat revascularization of the target vessel during index hospital stay.
Time frame: At procedure up to 12 hours
Resting ankle brachial index
Time frame: within 90 days of index procedure, and at 6, 12, 24 and 36 months post-index procedure

Change in Rutherford classification
Time frame: baseline, 30 days, 6, 12, 24, and 36 months
Change in 6-minute walk test
Time frame: baseline, 30 days, 6, 12, 24, and 36 months
Primary patency
defined as freedom from clinically-driven target lesion revascularization (TLR) and freedom from restenosis. Restenosis is defined by Duplex Ultrasound (DUS) peak systolic velocity ratio (PSVR) ≥ 2.5 (core lab assessed) or by ≥ 50% stenosis by QA (core lab assessed)
Time frame: 6 months
Continuous DUS Peak systolic velocity ratio (PSVR) as measured by Duplex ultrasound
Time frame: 30 days, 6, 12, 24, and 36 months
Late lumen loss
Defined as the difference in minimum luminal diameter of the target lesion between the index intervention and 6-month angiographic follow-up.
Time frame: baseline, 6 months
Quality of life
Assessed by Change in walking Impairment Questionnaire (WIQ) scores
Time frame: baseline, 30 days, 6, 12, 24, and 36 months
Evidence of Paclitaxel toxicity

Major vascular complications
Time frame: At hospital discharge, 30 days
Thrombolysis in Myocardial Infarction (TIMI)-defined major and minor bleeding
