ABSTRACT:
An electrode device for intracorporeal tissue stimulation, such as for intracardiac stimulation of heart tissue, includes an electrode cable containing at least one elongated, insulated conductor, and terminating in an electrode head at the distal end of the cable. The electrode head has a surface layer, which defines the shape of the electrode head, formed entirely of electrically conductive material, connected to the conductor, and thereby forming at least one stimulation surface. The surface layer is partially coated with high-resistivity insulating material, the coating forming a layer which is so thin that the difference in the distance between the uncovered portion of the stimulation surface and the heart tissue, and the distance between the insulating coating and the heart tissue, when the electrode device is applied to heart tissue, does not affect the threshold value for tissue stimulation.
