Catheters, Biliary, Brachytherapy
Definition : Biliary catheters designed for brachytherapy treatment of the biliary duct walls and gallbladder. These catheters are usually of a radiopaque single-lumen design; the catheter is inserted into the biliary ducts until its distal tip is close to the treatment area. The catheter is left in position and connected via an external tube to a remote-afterloading brachytherapy system that delivers the radioisotope through the catheter to the treatment site. The source (e.g., iridium 192) is usually welded to a stainless steel wire that is advanced into the catheter in fixed steps called dwell positions. Brachytherapy esophageal catheters are used for high-dose treatment of malignant tumors.
