An evaluation of the safety and performance of the STANZA Drug-eluting Resorbable Scaffold (DRS) system for the treatment of patients with obstructive superficial femoral artery disease.
The STANZA DRS system is comprised of a controlled release paclitaxel-eluting bioresorbable scaffold and a delivery system used in the treatment of superficial femoral artery disease.

Patency by Ultrasound
Patency measured by duplex ultrasound with ≤50% restenosis (Peak Systolic Velocity Ratio (PSVR ≤ 2.4).
Time frame: through 6 months
Major Adverse Events
Freedom from all causes of death, emergent endovascular intervention or surgical intervention on the target limb, index limb amputation.
Time frame: 30 days
Clinical Success
On a per patient basis, technical success without major adverse event (MAE) within 48 hours after the index procedure or at hospital discharge, whichever is sooner.
Time frame: 48 hours
Device Success
On a per device basis, the achievement of successful delivery and deployment of the study device at the intended target lesion and successful withdrawal of the delivery catheter.
Time frame: Procedure
Technical Success
Technical success is defined on a per lesion basis, as the achievement of a final residual stenosis of ≤ 30%.
Time frame: Procedure
Patency by Ultrasound
Patency measured by duplex ultrasound with ≤50% restenosis (PSVR ≤ 2.4) based on core lab evaluation at 12 and 24 months.
Time frame: 12, 24 months
Patency by Angiography
≤50% diameter stenosis determined by an angiographic core lab analysis of an angiogram performed at 12 months.
Time frame: 12 months
