Abstract
A high efficiency electrosurgical electrode with an advanced electrically conductive tip and aspiration port, and a method of conducting an electrosurgical procedure with such electrode. The electrosurgical electrode comprises an electrically conductive body portion of various geometries, an electrically conductive tip and a dielectric insulator adjacent the metallic body portion. The electrically conductive tip comprises a plurality of protuberances of various forms and geometries that define a plurality of recesses. The aspirating member includes a wall surrounding the aspirating port, to separate the aspirating port from adjacent recesses and prevent the flow of fluid from the recesses directly into the aspirating port.
