What this research studies

This project develops a thin, fully biodegradable 'Biocarpet' that doctors can deliver through a catheter into narrowed leg arteries. Once in place it conforms to the vessel and supports blood flow without the rigid outward force of traditional stents. The material is designed to gradually dissolve while encouraging healing, which could reduce vessel damage and repeat procedures. Early work will focus on laboratory and preclinical testing with the goal of moving to human trials if safety and durability are shown.

Who could benefit from this research

Good fit: Adults with peripheral artery disease affecting the femoral or popliteal (thigh/knee) arteries who are candidates for endovascular treatment could be ideal candidates.

Not a fit: People with heavily calcified or very small arteries, active infections, or who are not eligible for endovascular procedures may not benefit from this approach.

Why it matters

Potential benefit: If successful, the device could lower the chance of artery re-narrowing, reduce repeat procedures, and help prevent limb loss.

How similar studies have performed: Existing treatments like angioplasty, stents, and drug-coated balloons have limited two-year patency and this biodegradable, conforming 'carpet' approach is novel with little prior human data.
