ABSTRACT:
A catheter device and method for laparoscopically dilating the sphincter muscle to flush common bile duct stones into the duodenum is set forth where the catheter consists of a flexible tube having three lumens. An inflatable balloon is carried by the flexible tube at its distal end and is inflatable and deflatable through an insufflation port. Radiopaque markers placed distally and proximally of the balloon are used to visualize the location of the balloon flouroscopically. A guidewire is advanced through the cystic duct, common bile duct and into the duodenum over which the catheter is advanced and the balloon positioned at the juncture of the common bile duct and duodenum. The balloon is then inflated sufficiently to dilate the sphincter muscle; the balloon is then deflated and the common bile duct irrigated with a fluid injected through an irrigation port located proximally of the balloon to flush the gallstones from the common bile duct.
