Abstract

An end effector of an electrosurgical device may include a discharge port, an aspiration port, two electrodes, and a diverter formed from a porous material. The diverter includes a matrix having voids to receive fluid from the discharge port. A releasable diverter assembly may include an assembly body configured to receive a pair of electrodes and a diverter composed of a porous material. A shaft assembly of an electrosurgical device may include two electrodes and two fluid cannulae. Each cannula may be disposed proximate to a surface of each of the electrodes. An end effector of an electrosurgical device may include a fluid discharge port, two electrodes, and a diverter disposed therebetween. A proximal edge of the diverter may form a secant line with respect to the end of the discharge port so that fluid emitted by the discharge port is disposed on a surface of the diverter.
