<P>PROBLEM TO BE SOLVED: To provide a bipolar electrosurgical device to treat tissue by moving along a tissue surface in a presence of radio frequency energy and a fluid provided simultaneously from the device. <P>SOLUTION: The electrosurgical device is used with an electrosurgical unit comprising a radio-frequency (RF) power source and a pump, with the throughput of fluid expelled by the pump controlled by the RF power level setting and fluid flow rate setting. The electrosurgical device comprises a first electrode tip and a second electrode tip with a portion of the first electrode tip facing the second electrode tip and a portion of the second electrode tip facing the first electrode tip, the first electrode tip and the second electrode tip both having a spherical distal end, and a fluid outlet arrangement to expel fluid onto the electrode tips solely at locations remote from the electrode tip portions facing each other. <P>COPYRIGHT: (C)2011,JPO&INPIT |
