Breaking calcium to open blocked leg arteries
Part of Heart & circulation clinical trials.
This trial tests a new way to open blocked leg arteries using a special balloon that breaks up calcium and a device that reshapes the artery to improve blood flow. It may help relieve pain, heal wounds, and improve walking.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 or older.
- You must have significant pain with walking, pain at rest, or a non-healing wound on the affected leg.
- The blocked artery must be in the thigh or behind the knee, or in the lower leg below the knee.
- The narrowing must be at least 70% in the thigh area or at least 50% in the lower leg area.
- The artery must have significant calcium buildup (moderate or heavy).
- You must not have severe kidney disease or be on dialysis, and you must not be pregnant or nursing.
- If the blockage is in the lower leg, it must not be completely closed off.

This trial tests a new device that uses sound waves to break up calcium deposits in leg arteries, helping to improve blood flow and reduce symptoms like leg pain or wounds. It is for people with significant blockages above or below the knee.
This trial studies a device-based treatment approach for people with blocked (narrowed or fully blocked) arteries in the thigh or behind the knee that reduce blood flow to the leg. It may help improve blood flow and walking ability, but you must meet specific artery and imaging requirements.
This study tests a new balloon device that scores the artery walls to treat leg artery blockages with heavy calcium deposits. It aims to see if the device helps prepare the vessel safely and effectively before placing a stent.
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 trial tests a new approach to treat severe, hardened blockages in the leg arteries. It may help people with painful leg symptoms or wounds that won't heal.
This trial tests a new device that uses shock waves to break up calcium buildup in leg arteries, which can improve blood flow and reduce pain. It may help people with severe leg pain or wounds due to blocked arteries.
