Development of Retrieval Balloon Catheter to Remove Stones from The Biliary System

The retrieval balloon catheter has been established as an essential medical device for the management of obstructions, occlusions, and foreign body retrieval across multiple clinical specialties, including gastroenterology, vascular surgery, and interventional cardiology. Designed for minimally invasive applications, the catheter facilitates the removal of blockages while minimizing tissue trauma. The device is composed of biocompatible materials such as silicone, latex, and polyurethane, ensuring anatomical compatibility and reducing the risk of irritation. Advanced manufacturing techniques, including marker band swaging, soft tip molding, and assembly welding, contribute to its structural integrity and performance reliability. The catheter's functionality is enhanced by controlled balloon inflation and deflation, allowing for precise engagement with obstructions while ensuring procedural safety. Preclinical in vitro testing was conducted to evaluate the device’s efficacy, durability, and compliance with expansion specifications under varying pressures. These assessments confirmed consistent balloon inflation and deflation, structural resilience, and leak resistance. Clinical applications demonstrated high efficacy in the retrieval of bile duct stones, embolic material, and occlusive debris, with real-time imaging guidance ensuring accurate placement. The minimally invasive approach significantly reduced the need for open surgical procedures, leading to lower complication rates, shorter hospital stays, and improved patient recovery times. The retrieval balloon catheter has been validated as a reliable and effective tool in future after clinical trial. Ongoing advancements in material science and imaging integration are expected to further enhance its clinical utility, reinforcing its role in therapeutic interventions for gastrointestinal and vascular obstructions.
