ABSTRACT:
A thermotherapy catheter for heat treating the prostate gland includes an O-ring positioned within a chamber between an outer tube and an interior heat generation device guide tube. The O-ring supports a distal end portion of a probe guide tube at a desired acute angle so that a temperature probe can be advanced from the end of the probe guide tube into the prostate gland at a predetermined desired acute angle for calculating tissue heating and tissue necrosis information from temperature sensors located on a distal end of the temperature probe. The O-ring also separates a still liquid chamber from a circulatory flow path so that heated liquid surrounding the generation device is applied effectively to heat the prostate gland, while the circulating cooling fluid effectively removes heat from a feed cable which supplies energy to the heat generation device.
