Sound-wave treatment for leg artery calcium
Part of Heart & circulation, Hormones & metabolism clinical trials.
This study tests a new device that uses sound waves (lithotripsy) to break up hard calcium deposits in leg arteries for people with peripheral artery disease (PAD). It aims to safely open blocked arteries and improve blood flow, potentially reducing pain and improving walking.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have moderate to severe leg pain or leg wounds (Rutherford stage 2, 3, or 4) caused by blocked leg arteries.
- The artery in your leg has moderate or severe calcium buildup (hard plaque) that needs to be broken up.
- You are at least 18 years old and able to sign a consent form.
- You must not have had a heart attack or stroke in the last 60 days, and your kidney function must be normal.
- The blockage must be in a new (not previously treated) leg artery, not a stent or graft, and the total treated length must be under 22 cm.
- You should not be planning to use any other special devices like atherectomy or cutting balloons during this procedure.

This trial uses a special balloon (Shockwave IVL) to break up calcium in leg artery blockages, improving blood flow and reducing pain. It's for people with moderate to severe calcium buildup in the femoropopliteal artery.
This trial tests a new device that uses sound waves to break up calcium in leg arteries, helping to improve blood flow in people with peripheral artery disease. It may offer a new way to treat blocked leg arteries without major surgery.
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 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 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 trial tests a new device that uses sound waves to break up calcium deposits in heart arteries before placing a stent. It is for people with severely hardened arteries that are hard to treat with standard methods.
