ABSTRACT:
A medical probe device for medical treatment of tissue of a prostate through a urethra defined by a urethral wall. The device includes a probe housing having proximal and distal extremities and a longitudinal axis. A handle is mounted on the proximal extremity of the probe housing for introducing the distal extremity of the probe housing into the urethra so that the distal extremity of the probe housing is in the vicinity of the prostate. The device has first and second guide tubes provided with lumens therein and having distal extremities. The first and second guide tubes extend distally of the probe housing and extend at an angle with respect to the longitudinal axis to form a space between the distal extremity of the probe housing and the distal extremities of the first and second guide tubes. A plate having a rounded distal portion is secured to the distal extremities of the first and second guide tubes. The plate has holes therein in communication with the lumens in the first and second guide tubes.
