Abstract: A method and apparatus for transurethral resection of the prostate, which includes inserting a transurethral incisional device through the patient's urethra, incising off at least one piece of targeted prostatic tissue using the incisional device, inserting a morcellation probe through the patient's urethra, morcellating the excised piece of targeted prostatic tissue with the morcellation probe, and aspirating the morcellated prostatic tissue through the morcellation probe and out of the patient. The morcellation probe of the present invention includes an elongated inner probe tube that defines an aspiration channel therein and an aperture with opposing cutting edges formed adjacent to its distal end. The inner probe tube is slidably disposed inside an outer probe tube, and moves relative thereto in a longitudinal reciprocating manner. The outer probe tube has an open distal end and another aperture with opposing cutting edges.

The inner probe tube is slidably disposed inside an outer probe tube. The outer probe tube has a first aperture with a first cutting edge for cutting tissue. The inner probe tube has a second aperture or a spiral shaped groove defining a second cutting edge that moves relative to the first cutting edge to cut tissue drawn through the first aperture.
