摘要： A transurethral needle ablation device (21) comprising a bridge (22) having proximal and distal extremities and having a passage (236) therein extending from the proximal extremity to the distal extremity. A sheath (23) having proximal and distal extremities (42, 43) is secured to the bridge (22) and has a passageway (44) therein in communication with the passage (236) in the bridge. The sheath (23) is sized so that it can enter the urethra and has a length so that when its distal extremity (43) is in the vicinity of the prostate, the proximal extremity (42) is outside the urethra. A disposable needle assembly (26) having proximal and distal extremities is removably mounted in the passage (236) in the bridge (22) and extends through the passageway (44) in the sheath (23). The needle assembly (26) includes at least one needle electrode (101) and an insulating sleeve (91) coaxially disposed on the needle electrode. The proximal extremity of the needle assembly (26) is caused to be moved sideways at an angle with respect to the the longitudinal axis to face the urethral wall. A mechanism is carried by the proximal extremity of the needle assembly (26) and the bridge (22) for causing advancement of the needle electrode (101) and the insulation sleeve (91) thereon through the urethral wall and into the target volume in the tissue of the prostate.

摘要： An electrosurgical device (451) for medical treatment of tissue at a treatment site through a body opening. The device includes a sheath (452) having proximal and distal extremities and having a passageway (457) extending from the proximal extremity to the distal extremity. A guide tube (507) is slidably mounted in the passageway of the sheath and has proximal and distal extremities and a lumen (518) extending from the proximal extremity to the distal extremity. A needle electrode (633) is slidably mounted in the lumen of the guide tube and has proximal and distal extremities. Insulation (641) is coaxially disposed on the needle electrode. A handle (511) adapted to be gripped by the human hand is provided and the proximal extremity of the guide tube is mounted on the handle. An assembly (569) is carried by the handle for bending the distal extremity of the guide tube at an angle with respect to the longitudinal axis. The needle electrode is adapted to be coupled to an energy source (807). A single actuation element (669) is carried by the handle and coupled to the needle electrode and the insulation. The actuation element is movable in a single stroke from a first position in which the needle electrode and the insulation are disposed within the guide tube and a second position in which the needle electrode and the insulation are disposed in the tissue at the treatment site. A method for using the device is provided.

摘要： A medical probe device (21) comprising an elongate member (22) having proximal and distal extremities (22a, 22b) and first and second lumens (148, 28) extending from the proximal extremity (22a) to the distal extremity (22b). An opening (153) is provided in the distal extremity (22b) of the elongate member (22) in communication with the first lumen (148). A handle (29) is mounted on the proximal extremity (22a) of the elongate member (22a) for introducing the distal extremity (22b) of the elongate member (22) through the natural body opening into the canal. A scope (86) is positioned in the elongate member (22) and has a field of view which extends forwardly of the elongate member (22). A fitting (166) is coupled to the elongate member (22) for permitting a liquid to be suplied to the first lumen (148) and out the opening (153) to provide a clear field of view for the scope (86). The elongate member (22) is provided with at least one additional opening (182) proximal of the first named opening (153) in the elongate member (22) and in communication with the second lumen (28) for permitting aspiration of the liquid while liquid is being introduced through the first named opening (153) in the elongate member (22).
