ABSTRACT:
A medical probe for the treatment by radio frequency ablation of a target volume in tissue of a human having a urethral channel extending into a base of a bladder along a longitudinal axis. The probe comprises an elongate probe member having proximal and distal extremities and sized so that it can be introduced into the urethra. The elongate probe member has a passage extending from the proximal extremity to the distal extremity. Guide cannulae are mounted in the passage of the elongate probe member and have proximal and distal extremities with the distal extremities of the guide cannulae being in the vicinity of the distal extremity of the elongate probe member. Each of the guide cannulae has a lumen extending therethrough from the proximal extremity to the distal extremity. A radio frequency conductive electrode is disposed in each lumen. A control handle is secured to the proximal extremity of the elongate probe member. The control handle is connected to each radio frequency electrode whereby each radio frequency electrode can be advanced and retracted.
