Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients with symptomatic peripheral vascular occlusive disease and specific arterial measurements who can comply with follow-up requirements.
✕Probably not a fit
Patients with severe blood disorders, renal dysfunction, or liver impairment may not benefit from this treatment.

What this trial studies
This clinical investigation evaluates the safety and performance of the Efemoral Vascular Scaffold System (EVSS) in patients suffering from symptomatic peripheral vascular disease due to stenosis or occlusion of the femoropopliteal artery. It is a prospective, single-arm, open-label study that enrolls patients with specific arterial diameter and lesion length criteria. Participants will receive a single EVSS and will be monitored for outcomes related to their vascular health. The study aims to gather data on the effectiveness of this bioresorbable scaffold in improving blood flow and alleviating symptoms.
Why it matters
Potential benefit: If successful, this treatment could significantly improve blood flow and reduce symptoms for patients with peripheral vascular disease.
How similar studies have gone: Other studies using bioresorbable vascular scaffolds have shown promise, suggesting potential for success in this approach.
