ABSTRACT:
Method for performing a laparoscopic sphincterotomy involving the steps of positioning a catheter within the duodenum by inserting the distal end of the catheter into the common bile duct and threading the distal end of the catheter into the duodenum, positioning the cutting mechanism of the catheter against the sphincter of Oddi, cutting the sphincter of Oddi with the cutting mechanism, and removing the catheter. The invention also includes a surgical catheter to be used to perform such a sphincterotomy. The catheter includes an elongated longitudinal channel, two separate balloons located at the distal end of the catheter, and a cutting mechanism extendable from the catheter between the two balloons. The catheter also includes a radial mark at the operative end of the catheter that lies in the same radial position with respect to the longitudinal channel of the catheter as the cutting mechanism. The catheter and method disclosed allow a surgeon to perform a laparoscopic sphincterotomy that is safe and efficient, and allows a patient's gall stones, gall bladder disease, common duct stone, and inflammation of the ampulla to be treated during a single procedure.
