The purpose of this study (superiority trial) is to compare the Supera® Peripheral Stent System with a standard nitinol self-expanding stent for treatment of femoro-popliteal arterial occlusive disease.
Hypothesis:
The Supera® stent is superior to a standard nitinol self-expanding stent, for treatment of femoro-popliteal artery disease in terms of (1) primary patency rate and (2) need for revascularization up to 24 months after stent insertion.

| Supera® Peripheral Stent System | Device | The index procedure is placing a selfexpandable stent at a femoro-popliteal location. The way the stenosis or occlusion is traversed is not part of the study. It is mandatory to prepare then the vessel with PTA (at least the size of the stent) and thereafter insert the stent. Post-PTA can be performed with same balloon, but post-PTA is not mandatory to be performed. |
| Measure | Description | Time Frame |
|---|---|---|
| Difference in primary patency rate (proportion of patients classed as treatment succsess) | Peak systolic velocity ratio assessed with Duplex ultrasound (Treatment success is defined as Peak Systolic Velocity (PSV) ratio < 2.5 at the stented target lesion measured by Duplex ultrasound (DUS) indicating freedom from >50% restenosis with no clinically driven re-intervention within the stented segment.) | 24 months |
| Measure | Description | Time Frame |
|---|---|---|
| Difference in primary patency rate | Peak systolic velocity ratio assessed with Duplex ultrasound | 1 month, 6 months, 12 months |
| Difference in target lesion/vessel revascularization | Patients with target lesion revascularization due to restenosis or target vessel revascularization. |
| Measure | Description | Time Frame |
|---|---|---|
| Rate of site complications [Safety Endpoint] | 1 month | |
| Rate of prolonged hospital stay [Safety Endpoint] | 1 month | |
| Rate of need for surgical revision [Safety Endpoint] |
