Abstract: An apparatus and method is disclosed to resect and remove tissue. The apparatus is particularly suited for operation on the prostate for treatment of Benign Prostatic Hyperplasia (BPH). The apparatus has a deflectable member (18),which may be a wire, and which conducts electrosurgical current. The deflectable member (18) protrudes from an opening (22) near the distal end (13) of a hollow tube. Tissue is cut and coagulated by the deflectable member (18) asthe apparatus is rotated. A sharp tip on the distal end (13) of the tube allows the apparatus to be inserted percutaneously. Suction and irrigation are integral to the apparatus. One advantage of the apparatus is that tissue samples can be recovered for pathological analysis. Other advantages are that operations on theprostate can be conducted with minimal blood loss, concerns about TUR syndrome are reduced, and the bladder neck and urethra can be spared. Use of this device on the prostate also can eliminate the need for a post-operative catheter and provides immediate post-operative relief.
