Abstract
A transurethral apparatus for radio frequency ablation treatment of the prostate having prostatic tissue of a human male having urethra which extends through the prostate comprising an elongate probe sized so that it is adapted to be introduced into the urethra and having a passageway extending therethrough. The elongate probe has proximal and distal extremities. Proximal and distal pairs of needle electrodes are provided which are carried by the distal extremity of the probe. A control mounted on the proximal extremity of the probe and extends through the passageway and is coupled to the proximal and distal pairs of needle electrodes for movement of the needle electrodes into and out of the prostate. A RF generator is provided for supplying RF energy to the needle electrodes for solely creating bipolar ablation with respect to the proximal and distal pairs of needle electrodes.
