Abstract
A method for the treatment of benign prostatic hypertrophy in the prostate of the human male having a bladder with a base and a penis with a urethra therein formed by a urethral wall extending into the base of the bladder along a longitudinal axis with the prostate having tissue surrounding the urethral near the base of the bladder comprising selecting a target volume of the tissue of the prostate beyond the urethral wall, introducing radio frequency energy through the urethral wall into the target volume of the tissue of the prostate to cause ablation of tissue in the target volume of the tissue in the prostate and protecting the urethral wall from ablation by the radio frequency energy supplied to the target volume of tissue in the prostate.
