摘要:
A method for treating an individual with diseased prostatic tissue, such as benign prostatic hyperplasia, includes inserting a catheter (28) into a urethra (10) to position a microwave antenna (74) located within the catheter (28) adjacent a prostatic region of the urethra (10). A microwave antenna (74) is then driven within a power range for applying microwave energy substantially continuously to prostatic tissue (96) to heat the prostatic tissue (96) surrounding the microwave antenna (74) at a temperature and for a time period sufficient to cause necrosis of the prostatic tissue (96).
