An electrode assembly including an elongate body, a proximal emitter, and a distal emitter. A discharge port may be in fluid communication with a lumen of the elongate body. The proximal and distal emitters are formed by plating a metal an outer surface of the elongate body that is polymeric. A portion of the elongate body forms an insulative spacer between the proximal and distal emitters. A distal cap may be coupled to the elongate body, formed from conductive material, and arranged in electrical communication with the distal emitter. A distal lead, a thermocouple, and/or a hypotube may be disposed within the lumen to form an electrical pathway with the distal cap. A sheath may be disposed over a portion of the proximal emitter, and a radiopaque marker may be coupled to the proximal emitter. Methods of fabricating the electrode assembly are also disclosed.
