Abstract

An apparatus and method for warming the urethra of a patient during ablative surgery. In one embodiment, at least one ablative surgical device (14) is inserted into a prostate region of the patient. A Joule­-Thomson warming assembly (20) is inserted through the patient's urethra and into the bladder. The Joule-Thomson warming assembly is operated to warm an outer surface thereof during operation of the ablative surgical devices. The urethra is warmed by the outer surface of the Joule-Thomson warming assembly to preserve living tissue thereof. In another embodiment the portion inserted through the patient's urethra is an electrical coil heated warming catheter subassembly (42). In another embodiment the inserted portion is a microwave heated tube warming catheter subassembly. Another embodiment comprises an RF heated warming catheter subassembly. An opening is preferably provided to provide access for an endoscope or for fluid drainage.
