Abstract

An implantable stimulating electrode for directly contacting the endocardium of a human heart exhibits low polarization values of less than about 0.3 mV and is intended for use with an implantable lead having an electrical connector coupled to the proximal end of a conductor for releasable attachment to a stimulating pulse generator. The electrode is comprised of a metallic substrate having an initially exposed outer surface substantially covered with a first inner layer of titanium nitride and a second outer layer of platinum black. The first inner layer of titanium nitride has a thickness of less than about 15 microns and the second outer layer of platinum black overlying the layer of titanium nitride, similarly, has a thickness of less than about 15 microns. The invention includes a method of making the implantable stimulating electrode.
