Abstract

An implantable stimulation electrode for use with an implantable tissue stimulator, in particular a pacemaker, defibrillator, bone or neurostimulator, having a metal substrate body and a coating, applied to the substrate body, for reducing the electrode impedance and/or increasing the tissue compatability, in which a ultrathin, specifically functionalized organic coating forming the entire outer surface of the stimulation electrode is provided, which adheres to the underlying surface as a consequence of irreversible physisorption or covalent chemical bonding.
