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.
Claims20
An implantable stimulation electrode (1;
- 1';
- 10;
- E1, E2) for use with an implantable tissue stimulator (100), in particular a pacemaker, defibrillator, bone or neurostimulator, having a metal substrate body (1a, 1a';
- 11) and a coating (1b;
- 1b', 1c';
- 1b", 1d;
- 1b"';
- 12, 17), applied to the substrate body, for reducing the electrode impedance and/or increasing the tissue compatability, characterized in that
- a thin, specifically functionalized organic coating (1b;
- 1c';
- 1b", 1d;
- 1b"';
- 17) forming the entire outer surface of the stimulation electrode is provided, which adheres firmly to the underlying surface as a consequence of irreversible physisorption or covalent chemical bonding.
