604 22

A transurethral needle ablation device for use with the human hand for radio frequency ablation of a target volume in the 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. The device comprises a bridge having proximal and distal extremities and having a passage therein extending from the proximal extremity to the distal extremity. A sheath having proximal and distal extremities is secured to the bridge and has a passageway therein in communication with the passage in the bridge. The sheath is sized so that it can enter the urethra and has a length so that when its distal extremity is in the vicinity of the prostate, the proximal extremity is outside the urethra. A disposable needle assembly having proximal and distal extremities is removably mounted in the passage in the bridge and extends through the passageway in the sheath.

606 47

An electrosurgical device for medical treatment of tissue at a treatment site through a body opening. The device includes a sheath having proximal and distal extremities and having a passageway extending from the proximal extremity to the distal extremity. A guide tube is slidably mounted in the passageway of the sheath and has proximal and distal extremities and a lumen extending from the proximal extremity to the distal extremity. A needle electrode is slidably mounted in the lumen of the guide tube and has proximal and distal extremities. Insulation is coaxially disposed on the needle electrode. A handle 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 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.

606 41

A transurethral needle ablation device for use by a human hand to treat the prostate of a human male. The device includes a cartridge assembly having an elongate probe member and a stylet. The elongate probe member has proximal and distal extremities and is provided with a passageway extending from the proximal extremity to the distal extremity. The stylet is slidably mounted in the passageway of the elongate probe member. A housing is included in the device. The cartridge assembly is removably mountable on the housing. An assembly adapted for actuation by the human hand is carried by the housing and coupled to the proximal extremity of the stylet for causing the distal extremity of the stylet to extend into the tissue of the prostate.

A surgical irrigation system is suitable for endoscopic and other surgical procedures. A hand held handpiece has a forward protruding hollow tip for supplying irrigation liquid to a surgical site, a hand actuable control for controlling irrigation liquid flow to the tip, and an irrigation liquid inlet. A self contained pumping unit is locatable adjacent a source of irrigation liquid and remote from the handpiece. The pumping unit comprises a housing containing an outlet for irrigation liquid, a pumping member for pumping irrigation liquid through the outlet, a motor for driving the pumping member, and an electric battery assembly for energizing the motor. An elongate tube connects the pumping outlet to the handpiece irrigation liquid inlet for supplying pumped irrigation liquid to the handpiece.

An inventive surgical handpiece comprises a handle unit and structure carried by the handle unit for engaging a patient. A hand actuable element is mounted for rotation on the handle unit, about first and second mutually transverse axes. A first mechanism is responsive to rotation of the hand actuable element about its first axis for imparting first degree of freedom movement to the patient engaging structure. A second mechanism is responsive to rotation of the same hand actuable element about its second axis for imparting second degree of freedom movement to the patient engaging structure.
