Patent abstract
Coatings for implantable electrodes such as pacing electrodes, neurostimulator electrodes, and electroporating electrodes and sensing electrodes are described. The coatings are highly biocompatible, having low polarization. They consist of a biocompatible, conductive substrate, such as of sintered platinum/10% iridium; a thin film outer layer of biocompatible, conductive carbon; and a biocompatible, conductive intermediate layer having a high surface area. The intermediate layer is preferably of sputtered titanium nitride and increases the surface area of the carbonaceous outer layer.
