Patent attributes
A catheter system is provided that permits easy cannulation and radiological examination of the biliary and pancreatic ducts during an Endoscopic Retrograde Cholangiopancreatograhy (ERCP) procedure. The system of biliary catheters provides for a method of gaining access to the biliary tree, particularly when the contralateral wall or septum of the biliary tree interferes with access to the biliary tree. This anatomical interference is remedied using a pulling biliary catheter that withdraws the papilla of Vater away from the contralateral wall or septum by pulling proximally upon a chute expanded within the papilla of Vater. The enlarged opening then permits additional medical devices to be advanced through the pulling biliary catheter into the desired duct requiring the ERCP procedure.
