Abstract:
A method for removing tissue from within a body cavity of a patient through an incision in the patient comprising:providing a morselating apparatus comprising an elongated shaft having proximal and distal end portions, the elongated shaft being rotatable and having a lumen extending between the proximal and distal end portions with a first electrode being carried on the distal end of the elongated shaft;providing a second electrode;inserting through an incision in the patient the distal end of the elongated shaft and the second electrode;contacting the tissue to be removed with the second electrode;energizing the first electrode by electrically coupling the electrode to a source of radio frequency energy;rotating said elongated shaft and the electrode;engaging the tissue to be removed with the energized rotating electrode to morselate the tissue; andremoving the morselated tissue through the lumen of the elongated shaft.
