Clearing blocked lower-leg arteries with a new catheter
Part of Heart & circulation clinical trials.
This study tests a new catheter system that removes blood clots and clears blockages in the arteries below the knee. The goal is to improve blood flow to the foot and help people with severe leg pain or wounds.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be at least 18 years old
- You must have a severe blockage in the lower-leg arteries (called Rutherford category 4–6)
- The artery where the catheter will be placed must be between 3.5 mm and 6 mm wide
- The main arteries that supply the lower leg must have no more than 30% narrowing (they may be opened during the procedure if needed)
- You cannot have had surgery or a stent in the treatment area within the last month
- You must not have an active infection, severe artery bending, or completely blocked and calcified arteries in the target area

This study tests a special catheter to open blocked arteries in the thigh, knee, or lower leg. It may help improve blood flow and reduce symptoms like leg pain or wounds.
This trial tests a two-step treatment for long blockages in the leg artery: first, a device clears the plaque, then a drug-coated balloon is used to keep the artery open and prevent re-narrowing. It aims to improve blood flow and reduce symptoms like leg pain or wounds.
This trial tests a special balloon that releases medication to help keep leg arteries open. It's for people with narrowed or blocked arteries in the leg, either above or below the knee.
This study is testing a new drug-coated stent for blocked arteries in the thigh or behind the knee. It may help people with moderate to severe leg pain or wounds by improving blood flow without needing surgery.
This trial tests a special preparation method (breaking up calcium) plus a Supera stent versus standard preparation plus stenting for people with severe calcium buildup and long blockages in the thigh or behind-the-knee artery. It aims to see which approach works better for opening the artery and keeping it open.
This study compares two ways to open a blocked artery in the thigh or behind the knee. Both are minimally invasive procedures, and the goal is to see which one works better for long or complex blockages, possibly improving blood flow and reducing leg pain.
