Tiny trial tests artificial vein valve for leg swelling
NCT ID NCT05883943
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tests a new device called the Cook® Venous Valve System in just 4 people with chronic venous insufficiency (leg veins that don't pump blood back to the heart properly). The valve is implanted through a small tube into a deep leg vein to help blood flow one way. The main goal is to check safety in the first 30 days, with follow-ups up to a year.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Cook® Venous Valve System (a permanent prosthetic valve implanted in the leg vein)
What this could lead to
If it works, this could offer a new treatment option for chronic venous insufficiency, potentially reducing leg swelling and pain.
What could go wrong
This is a very early, tiny study with only 4 people. The device may not work as hoped, and risks include blood clots, bleeding, or device movement.
