iCover Stent Safety and Performance in Complex Aortic Aneurysm Repair
This trial tests a special covered stent (iCover) used during a minimally invasive procedure to repair complex abdominal aortic aneurysms—life-threatening bulges in the main artery in your belly. The stent helps keep important blood vessels open during the repair.
BonheidenAges 55 years+ - NCT06968858RecruitingPhase 1/Phase 2
Testing a new device to find blocked heart stents
This trial tests a new, non-invasive device that uses microwaves to detect if a heart stent is blocked. If you have a stent and are scheduled for a heart catheterization, this study may help see if the device works as well as the standard procedure.
Badalona, CataloniaAges 18 years+ - NCT07742358Recruiting
Comparing ureteral stent designs in children with kidney stones
This trial compares two types of ureteral stents (small tubes that help urine drain from the kidney to the bladder) in children having surgery for kidney stones. The goal is to see which type causes fewer symptoms like pain or discomfort.
Toronto, OntarioAges 8–18 - NCT05390983Recruiting
Compare surgery vs balloon/stent for re-narrowed neck artery
This trial compares two treatments for a carotid artery that has narrowed again after a prior stent: surgery (endarterectomy) versus repeat balloon treatment with or without stenting. It may help find which approach works better to prevent further narrowing and complications.
Ostrava, Moravian-Silesian RegionAges 18–80 - NCT05345483Recruiting
Rescue stent after failed clot removal in brain arteries
This trial looks at using a special stent device to reopen a blocked brain artery when a standard clot-removal procedure did not work. It may help restore blood flow and reduce damage, especially when the stroke area on scans is small enough and the symptoms started within 24 hours.
AschaffenburgAges 18 years+ - NCT04948749Recruiting
Stenting plus medication to prevent stroke from narrowed brain arteries
This trial tests whether placing a stent in a severely narrowed brain artery, along with aggressive medication, can prevent another stroke better than medication alone. It is for people who had a mild stroke within the last 30 days due to a 70-99% blockage in a major brain artery.
Beijing, Beijing MunicipalityAges 18–85 - NCT04443530Recruiting
Testing Ultimaster stents in everyday patient care
This trial looks at how safe and effective two specific stents are when doctors use them as part of routine care. You may be a candidate if you’re an adult receiving one of these Ultimaster stents and can follow the study check-in schedule.
ChuncheonAges 19 years+ - NCT05544864Recruiting
Stent or balloon treatment guided by heart scar pattern
This study looks at how to treat blocked heart arteries that have narrowed again after a prior drug-eluting stent. It compares using another drug-eluting stent versus a drug-coated balloon, chosen based on an imaging scan inside the artery (OCT), to reduce repeat narrowing.
Frankfurt am Main, HesseAges 18 years+ - NCT05811364Recruiting
Stent versus bare-metal treatment for blocked leg arteries
This study compares a new balloon-expandable stent to standard bare-metal stenting to treat complex blockages in the iliac arteries (main blood vessels to the legs). It may help people with symptoms like leg pain with walking, pain at rest, or minor tissue injury by improving blood flow and reducing repeat procedures.
Little Rock, ArkansasAges 18 years+ - NCT06002932Recruiting
Comparing one-stent with drug balloon vs. two-stents for heart artery branches
This study compares two ways to treat a narrowed heart artery where a smaller branch vessel is also blocked. One approach uses a drug-coated balloon on the side branch, while the other places a second stent. The goal is to see which method works better for patients like you.
Suwon, Gyeonggi-doAges 19 years+ - NCT06655051Recruiting
Plastic versus metal stent for bile duct blockage from chronic pancreatitis
This study compares two types of stents (plastic vs. metal) to see which works better for treating bile duct narrowing caused by chronic pancreatitis. If you have a bile duct blockage from chronic pancreatitis, you may be eligible.
