This study tests a special stent and a brain protection system in 60 Chinese patients with narrowed carotid arteries. The goal is to see if the device can be safely delivered and prevent strokes during the procedure. Participants must have significant artery narrowing and either …

This study tests a device called Orbera365, a balloon placed in the stomach to help people with obesity lose weight. About 144 adults with a BMI between 28 and 50 who have not succeeded with diet and exercise will take part. The balloon is inserted without surgery and left for up…

This small pilot study will test whether stimulating two brain areas at once—the subthalamic nucleus and the centromedian thalamus—can safely reduce seizures in adults with drug-resistant motor epilepsy. Ten participants will receive the stimulation and be monitored for changes i…

This study will test if a procedure called endoscopic sleeve gastroplasty (ESG) using the OverStitch NXT system is safe and helps obese adults lose weight. About 136 Asian participants with a BMI of 27.5 or higher will be enrolled. The main goal is to see if at least 5% of total …

This study looks at doing two heart procedures at the same time for people with atrial fibrillation (an irregular heartbeat). The first uses pulsed field ablation to fix the heart's electrical problem, and the second closes off a small pouch in the heart to lower stroke risk. Abo…

This study will track 5,000 people with carotid artery disease who receive a procedure called TCAR using the ENROUTE system. The goal is to see how well the treatment works in everyday medical practice and to collect information on costs and patient outcomes. The study will monit…

This study is collecting real-world data on how well the EKOS device works for patients in China with a sudden, severe blood clot in the lungs. The device uses ultrasound waves and delivers a clot-busting drug directly to the clot. Researchers will track 30 patients to see how th…

This study aims to collect breathing data from 50 healthy adult volunteers using two methods: measuring carbon dioxide in exhaled breath (end-tidal CO2) and a standard lung function test (spirometry). The goal is to compare how well these methods detect breathing rate. Participan…

This study aims to understand how signals from a wearable heart monitor can detect fainting caused by drops in blood pressure or reflex responses. About 40 adults who have been diagnosed with orthostatic hypotension or vasovagal syncope will wear the monitor during clinic visits …

This study collects ultrasound images from inside the heart during a planned ablation procedure for atrial arrhythmia. The images will be used to develop and validate software, not to treat participants directly. About 200 adults scheduled for ablation will take part.
