Clot removal device for severe leg blockages
Part of Heart & circulation clinical trials.
This trial tests a device called the Protexus catheter, which removes blood clots and debris during leg artery procedures. It is for people with severe blockages below the knee who are already scheduled for balloon angioplasty or atherectomy.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older
- You have moderate to severe leg symptoms (Rutherford class 4-6), like pain at rest, a sore that won't heal, or tissue damage
- You are scheduled for a procedure to open arteries below the knee using a balloon, atherectomy (plaque removal), or other minimally invasive methods
- The target artery is between 3.5 mm and 6.0 mm wide (about the size of a pencil lead to a drinking straw)
- The arteries bringing blood to your leg have less than 30% narrowing, or can be opened to less than 30% during the procedure
- You do not have a stent or recent treatment (within 30 days) in the area where the device will be used

Other trials that look related to this one.
This trial looks at whether using a scraping device (atherectomy) followed by a drug-coated balloon works better for long blockages in the thigh-to-knee artery. It may help improve blood flow symptoms and keep the artery from re-narrowing, but you must meet specific artery and health criteria.
This study tests a device called JETi® that uses a tiny jet of fluid to break up and remove blood clots in leg arteries. It may help people with sudden or recent leg artery blockages improve blood flow and avoid more serious complications.
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 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 trial checks how well a device called the Pantheris Small Vessel System works to treat blocked small blood vessels in the foot/leg. It may help people improve circulation, but you must meet specific health and follow-up requirements.
This trial studies a drug-eluting dissolving scaffold placed in blocked arteries below the knee to improve blood flow. It may help people whose leg circulation problems are severe enough to limit walking or threaten the limb, but only if their blockages fit specific imaging and procedure requirements.
