Abstract:
A medical probe device for the treatment by radio frequency ablation of a target volume in tissue of a prostate of a 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 tissue of the prostate surrounding the urethra near the base of the bladder comprising an elongate probe member having proximal and distal extremities and a longitudinal axis and having a passageway therein extending from the proximal extremity to the distal extremity along the longitudinal axis, the elongate probe member being sized to be able to enter the urethra and having a length so that when the distal extremity is disposed in the vicinity of the prostate the proximal extremity is outside of the urethra, a stylet mounted in the passageway of the elongate probe member and having a distal extremity, a handle coupled to the proximal extremity of the elongate probe member and extending in a direction which is substantially off-axis with respect to said longitudinal axis, finger actuatable means carried by the handle and connected to the stylet for causing advancement of the stylet through the passageway, the distal extremity of the elongate probe member being in communication with the passageway and the distal extremity of the stylet being advanceable out of the passageway sidewise in said same direction into the tissue of the prostate.
