Abstract
Relief of urethral obstruction is achieved by heat ablation of prostatic tissue by an ablation probe passed within the urethra to a position in the prostate near the point of urethral obstruction. The probe is coupled to a power supply to deliver power to tissue near the probe and thus to ablatively heat the urethra and the prostatic tissue near the urethra. The temperature of the tissue is sensed at the probe to control the heating and ablation process. In one embodiment, the probe has a blunt tip to help prevent piercing of the wall of the urethra during insertion of the probe into the urethra through the penis and the positioning of the probe tip near to the point of urethral obstruction. Several forms of probes, apparatus, and methods accommodate the specific objectives.
