Abstract
A bipolar electrosurgical device includes a shaft and an electrode tip coupled to a distal end of the shaft. At least a portion of the electrode tip extends distally beyond the distal end of the shaft and includes an insulator extending between a first electrode and a second electrode. The first electrode is configured to he an active electrode and the second electrode is configured to be a return electrode. The electrode tip can include a substantially conically-shaped portion, or can include a spherical portion and a cylindrical portion protruding from the spherical portion at a non-zero angle with respect to a longitudinal axis of the shaft. The substantially conically-shaped portion can include at least a portion of one of the first electrode and the second electrode. The distal end of the shaft can include a fluid outlet opening to provide fluid from a fluid source onto the first electrode and the second electrode.
