A dissolving stent for blocked leg arteries below the knee
Part of Heart & circulation clinical trials.
This study tests a new bioresorbable scaffold (like a temporary mesh) that slowly dissolves, releasing medication to keep your below-the-knee artery open. It is for people with severely blocked leg arteries causing pain or wounds at rest (Rutherford 4 or 5).
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 to 90 years old.
- You have chronic limb-threatening ischemia (severe leg pain or wound at rest) rated as Rutherford category 4 or 5.
- The narrowing in your leg artery below the knee must be new or restenosed (not a previously placed stent) and at least 70% blocked.
- The artery being treated must be 3.0 to 3.5 mm in diameter, and the total length of all blockages treated cannot exceed 11 cm.
- You cannot have had a prior stent or bypass in the target artery, and you must not need a major amputation on the treated leg.
- You must be willing to have follow-up visits and angiograms (x-ray dye tests) for at least 12 months.

This trial tests a special stent-like device placed in blocked arteries below the knee to improve blood flow in people with critical limb ischemia. If you meet the artery and health requirements, the goal is to reduce artery re-blocking and help prevent worsening leg problems over 12 months.
This trial tests a new stent to improve blood flow in blocked leg arteries causing severe pain or tissue loss. It may help if you have a long blockage in the upper leg but not below the knee.
This trial studies a new stent-like vascular scaffold to improve blood flow in people with symptomatic blockage in the thigh/knee artery. It may help reduce symptoms from narrowed or blocked arteries, but you must meet several artery and health requirements.
This trial studies a drug-eluting dissolving scaffold placed in blocked arteries below the knee to improve blood flow. It may help people whose leg circulation problems are severe enough to limit walking or threaten the limb, but only if their blockages fit specific imaging and procedure requirements.
This trial tests a new dissolvable stent that slowly releases medicine to keep your lower-leg artery open. It is for people with severe leg pain or small wounds due to poor blood flow, and who are not eligible for other stents.
This trial tests a new type of absorbable scaffold (like a temporary mesh) that is placed inside a blocked artery below the knee to restore blood flow. It is for people with severe leg pain or small ulcers due to chronic limb-threatening ischemia (CLI) who have a short blockage in a specific artery.
