Abstract
A disposable electrode paddle assembly is provided and includes a shaft having a proximal end and a distal end; a handle assembly supported at the proximal end of the shaft; a spoon supported at the distal end of the shaft; an electrical conductor extending from the handle assembly and establishing an electrical connection at the spoon; and an electrode assembly selectively, electrically connectable to the electrical connection provided at the spoon; wherein the electrode assembly includes a layer of silver/silver-chloride (Ag/AgCl) having one of an increasing and decreasing density extending in a radially outward direction.
