Shockwave balloon to crack calcium before neck artery stenting
Part of Brain & nervous system, Heart & circulation, Hormones & metabolism clinical trials.
This trial tests a special balloon that uses sound waves to crack hard calcium buildup in the neck artery before placing a stent. The goal is to make stenting safer and more effective for people with heavily calcified blockages, which may help prevent strokes.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older.
- You have a blocked carotid artery (the main artery in your neck) that is at least half closed if you've had symptoms like a mini-stroke, or at least 70% closed if you haven't had symptoms.
- The blockage is in a spot where your doctor can place a stent (a small mesh tube) through a tube in your leg.
- Imaging (like a CT scan) shows the blockage has a thick layer of calcium (at least 3 mm) that needs to be cracked before stenting.
- You are considered high risk for open neck surgery, for example because of age, heart, lung, or other medical conditions, or because of previous neck treatments.
- You are not on dialysis and do not have other major health problems that would make the procedure unsafe.

This study tests a special balloon that uses sound waves to break up calcium buildup in the carotid artery (the main artery in your neck) before placing a stent. It's for people who are at high risk for traditional surgery and have heavy calcium deposits in their artery.
This trial tests a special balloon (IVL) to treat hardened plaque in the neck arteries that supply blood to the brain. It is for people who need a stent but whose previous balloon treatment did not work well.
This trial tests a new single-use balloon catheter that uses sound waves to break up hardened calcium in heart arteries before placing a stent. It may help people with severe calcified blockages or completely blocked arteries that are hard to treat.
This trial tests a special balloon that uses shock waves to crack calcium in heart arteries, making it easier to place a stent. It is for people with chest pain or signs of heart strain due to a single, severely blocked artery with dense calcium.
This trial tests a stent procedure to open a severely blocked carotid artery in people who have not had a stroke or mini-stroke from that blockage recently. It aims to see if the procedure is safe and effective for preventing future strokes.
This trial tests a special device that uses sound waves to crack hard calcium in heart arteries, helping a stent expand fully after it was placed too tightly. It's for people who have a calcified artery where the stent didn't open enough, even after standard balloon treatment.
