New stent aims to keep leg arteries open longer
NCT ID NCT04546477
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This trial is testing a new stent called Renzan to treat blockages in the leg arteries (superficial femoral or popliteal arteries). The study includes about 135 people with moderate to severe peripheral artery disease. Researchers want to see if the stent is safe and effective at keeping the artery open for at least a year, preventing the need for repeat procedures or amputation.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Renzan peripheral stent system
- What this could lead to
- If successful, this stent could offer a reliable option to restore blood flow in blocked leg arteries, reducing pain and the need for repeat procedures.
