Patent ID: 7850684

Claim:
A morcellating system comprising an electrosurgical generator and a morcellating device for morcellating tissue within a body cavity of a patient, the morcellating device comprising a stationary tube having a distal end portion, and a bipolar electrosurgical electrode assembly comprising first and second electrodes located at the distal end of the tube and separated one from the other by an insulation member, the bipolar electrosurgical electrode assembly being connectable to the electrosurgical generator such that an electrosurgical cutting voltage can be applied to the electrode assembly, the electrosurgical generator being adapted to supply the electrosurgical cutting voltage to the electrode assembly in the form of a pulsed cutting voltage, the pulsed cutting voltage being a shaped waveform in the form of a generally tapered profile, the pulsed cutting voltage being reduced from a predetermined maximum voltage level to a predetermined minimum voltage level after the initiation of a cutting plasma around an active one of the first and second electrodes.
