Abstract
Methods and apparatus for delivering, monitoring, balancing, and/or dispersing high-frequency current flow in monopolar electrosurgery. The methods generally include positioning an active electrode in or on target tissue, positioning at least two dispersive electrodes on tissue remote from the target tissue, establishing electrical current flow from the active electrode through the dispersive electrodes, and individually adjusting the current through at least one of the dispersive electrodes to balance the current through the dispersive electrodes. By adjusting and balancing the current through two or more dispersive electrodes, safety of electrosurgical systems may be enhanced by preventing unwanted patient burns.
