<p>An electrosurgical electrode (100) capable of achieving instant ignition in a conductive fluid (91) and a method of conducting an electrosurgical procedure with such an electrode are disclosed. The electrosurgical electrode comprises a metallic body portion (52) of various geometries, a metallic tip (55,65,75,85) and a dielectric insulator (50) adjacent the metallic body portion. The metallic tip (55,65,75,85) is recessed from the surface of the dielectric insulator (50) so that the dielectric material (50) and the adjacent recessed metallic tip (55,65,75,85) form a high current density zone and pocket (96a,96b) for bubble (97) entrapment and instant spark (98) formation. <IMAGE></p> |
