Abstract:
A medical probe device for treatment of a prostate of a human male having a bladder with a base with a urethra formed by a urethral wall extending into the base of the bladder 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 a passageway extending from the proximal extremity to the distal extremity along the longitudinal axis, the elongate probe member having a length so that when the distal extremity is disposed in the urethra in the vicinity of the prostate the proximal extremity is outside the urethra, handle means coupled to the proximal extremity of the elongate probe member for introducing the distal extremity of the elongate probe member into the urethra, a stylet slidably mounted in the passageway of the elongate probe member, a guide piece mounted on the distal extremity of the elongate probe member, the guide piece having a proximal extremity and a rounded distal end and an internal curved surface for directing the stylet sidewise of the longitudinal axis into the tissue of the prostate, an optical viewing device mounted within the passageway of the elongate probe member and having a distal extremity with a field of view positionable in the vicinity of the guide piece, the guide piece being made from a transparent material to permit viewing by the distal extremity of the optical view device forwardly and sidewardly of the guide piece.
