Abstract
Apparatus using microwave energy for the therapeutic and hyperthermic treatment of an internal body organ such as the prostate gland. An irregularly shaped coaxial applicator having a narrow portion and a wide portion is inserted through the male anus into the rectum such that a substantially maximum intensity of the microwave energy irradiates the prostrate gland for preferential heating of the prostate gland and a substantially minimum intensity irradiates untreated tissue. Temperature sensing means are positioned on the periphery of the applicator to measure the tissue environment irradiated by the microwave energy. A controller, operating with the temperature sensing means, is provided to maintain the temperature of the tissue environment within a desired temperature range.
