ABSTRACT:
A transmural cardiac electrode includes a base member and at least one hollow needle projecting from it. Each needle has at least one opening in the wall communicating with the hollow center of the needle, and a sintered Ag/AgCl electrode element is positioned within each opening, shielded from electrical contact with the needle, and cemented in position with a nonconducting material. Initially, the electrode element extends beyond the periphery of the needle, but after it is cemented in position it is ground down to conform with the external surface of the needle. An insulated wire is in electrical communication with each electrode element and extends from the opening along the inside of the needle toward and through the base member.
