The present disclosure includes an electrosurgical apparatus for treating tissue at a target site. The apparatus has a shaft with a proximal end and a distal end, and the distal end includes an active disposed laterally on the shaft distal end and return electrode. The return electrode may have a plurality of apertures through it, which are fluidly connected to a fluid delivery element, operable to deliver a conductive fluid to the shaft distal end. The return electrode may encircle at least a portion of the shaft and may extend distally and proximally from the active electrode.
