Stent Implantation clinical trials

Long-Term Study of Castor and Cratos Stents for Aortic Arch Repair

This study tracks how well two types of stents (Castor and Cratos) work for people who have had a repair of the main artery in the chest (the aortic arch). If you already received one of these stents during your procedure, the study will follow your recovery and any future aortic events.

Biodegradable stent for bile duct narrowing after liver transplant

This study is testing a special temporary stent that breaks down over time to help open a narrowed bile duct after a liver transplant. It may help avoid long-term plastic stents or additional surgery.

Stent or standard treatment for idiopathic intracranial hypertension

This Phase 3 trial compares putting in a venous sinus stent versus using medicine alone for idiopathic intracranial hypertension (IIH). It aims to see which approach better protects vision and lowers pressure in the brain.

Registry study of Minos stent-graft for abdominal aortic aneurysm

This study tracks the long-term safety and effectiveness of the Minos stent-graft system in treating abdominal aortic aneurysms. It collects data from patients across Europe and Asia to see how well the device works over five years.

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.

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.

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.

Balloon vs stent for new heart blockages

This trial compares two treatments for new blockages in heart arteries: a drug-coated balloon (a tiny balloon that delivers medicine) versus a drug-eluting stent (a small mesh tube that releases medicine). The study hopes to see which approach keeps the artery open longer and is safer over time.

This Prospective Observational Study Aims to Evaluate the Capability of Ultra-high-resolution Photon-counting CT Angiography (UHR PCD-CTA) for Noninvasive Evaluation of Intracranial Venous Sinus Stents. The Study Will Compare Image Quality, Stent Visualization, Metal-related Artifacts, and Diagnosti

Clopidogrel vs aspirin after heart stent treatment

This trial compares two blood-thinning medicines—clopidogrel and aspirin—after you have finished a short period of dual therapy following a special type of drug-eluting heart stent. It may help find which medicine works better and is safer for preventing future heart problems.

Study of a new way to check branch blockages after stent placement

This trial looks at a new method called µQFR to check if there are any significant blockages in the side branches of heart arteries after a single stent has been placed. It aims to see if this method can help doctors decide if more treatment is needed.

Compare two stent types for blocked thigh artery disease

This trial compares a special drug-coated balloon/stent strategy versus a standard stent approach for people with blocked thigh artery segments. It aims to improve how long the artery stays open and reduces repeat procedures.

Perioperative antiplatelet therapy for abdominal surgery after stent

This study looks at the best way to manage your blood-thinning medicine (antiplatelet therapy) around the time of abdominal surgery, if you have a coronary stent. The goal is to help reduce the risk of heart problems while keeping bleeding risks low.

Single anticoagulant blood thinner after stent in atrial fibrillation

This trial tests whether taking a single “P2Y12 inhibitor” blood thinner (instead of multiple medicines) is safe and effective after you get a coronary stent. It’s for people with atrial fibrillation who need long-term blood thinning and have recently had a successful stent procedure.

Comparing two surgeries for acute aortic dissection

This trial compares two surgical methods for repairing the main artery (aorta) after a tear (dissection) that starts in the upper chest. One method replaces part of the aorta, and the other adds a stent. The goal is to find which approach works better for patients.

Comparing two methods to guide heart stenting

This study compares two ways to guide stenting for blocked heart arteries: one uses a pressure wire (FFR) to measure blood flow, and the other uses ultrasound (IVUS) plus a computer estimate of blood flow. The goal is to see which approach leads to better outcomes after stent placement.

Indobufen vs aspirin after stent in older heart patients

This trial tests whether a blood thinner called indobufen works as well as aspirin for older people (65+) who have had a heart attack or unstable angina, received a drug-eluting stent, and are already taking two blood thinners. The goal is to find a safer or better option for long-term prevention.

Comparing two ways to treat hardened calcium in heart arteries

This trial compares two techniques (orbital atherectomy and intravascular lithotripsy) to break up tough calcium deposits in the heart's arteries that can block blood flow. If you have a calcified nodule and are having a non-emergency procedure to open a blocked artery, this study may help guide which method works best.

Comparing heart artery treatments in people with diabetes

This study compares using a special medicated balloon plus a medicated stent versus using just one of them to open blocked heart arteries in people with diabetes. It aims to find which treatment works better to keep arteries open longer.

Inhaled Aroxxen to protect the heart during stent placement

This trial tests whether an inhaled medication called Aroxxen® can protect your heart during a planned stent procedure. It may help reduce stress on the heart muscle.

Treatment for retrograde aortic dissection with a stent graft

This trial tests a stent-graft procedure for a specific type of aortic dissection where the tear starts in the arch or descending aorta and extends backward into the ascending aorta. It is for patients who are not good candidates for open surgery.

Long-term look at Hydrus stent after 8 years

This study is checking how the Hydrus implant (a tiny device for glaucoma) is doing more than 8 years after it was placed. It aims to see if the eye pressure is still controlled and if the eye is healthy. If you were in one of the earlier Hydrus studies in Mainz and had the implant with or without cataract surgery, this follow-up may be for you.

Atorvastatin before flow diverter for brain aneurysms

This trial tests whether taking atorvastatin before a flow diverter procedure can prevent strokes or other brain events in people with unruptured brain aneurysms. It may help reduce complications from the treatment.

Artificial bronchus implant for severe emphysema

This trial tests an implantable artificial bronchus to help people with severe emphysema breathe easier. It's for those who have stable COPD, can walk 100–400 meters in 6 minutes, and haven't smoked for at least 4 months.
