Abstract
An electrosurgical device is provided which comprises a distal portion having a bipolar electrode configuration and at least one fluid outlet opening. The device further includes a first electrode tip spaced from a second electrode tip with the first electrode tip to serve as a first pole of the bipolar electrode configuration and the second electrode tip to serve as a second pole of the bipolar electrode configuration. The first and second electrode tips are configured to slide over a tissue surface in the presence of a fluid provided from the fluid outlet opening and an electrical current provided from the electrode tips.
