Electrode assembly including plated emitters

An electrode assembly comprising:

• an elongate body comprising an outer surface opposite an inner surface defining a first lumen, a second lumen fluidly separated from the first lumen, and a discharge port in fluid communication with the second lumen, wherein the elongate body is formed from non-conductive material;
• a proximal emitter formed from plating a metal on a first portion of the outer surface, wherein the plated metal defines a discharge port in fluid communication with the second lumen;
• and
• a distal emitter formed from plating the metal or another metal on a second portion of the outer surface, wherein the first portion and the second portion are spaced apart from one another such that the elongate body forms an insulative spacer between the proximal emitter and the distal emitter,
• wherein the first lumen defines a fluid pathway for fluid received from a fluid source to be discharged through the discharge port, and the second lumen defines an electrical pathway for electrical components of the electrode assembly.

An electrode assembly comprising:

• an elongate body formed from a flexible polymer comprising an outer surface opposite an inner surface defining a lumen and a discharge port in fluid communication with the lumen;
• a proximal emitter formed from plating a metal on a first portion of the outer surface;
• a distal emitter formed from plating the metal or another metal on a second portion of the outer surface, wherein the first portion and the second portion are spaced apart from one another such that the flexible polymer of the elongate body forms a flexible insulative spacer between the proximal emitter and the distal emitter;
• and a proximal lead coupled to the proximal emitter, wherein the lumen extends longitudinally within a portion of the elongate body and further extends radially outward to the discharge port, and wherein the proximal lead is disposed within the lumen.
