Abstract
The invention relates to an implantable carbon electrode. With such an electrode, the energy loss -- occurring after the implantation -- is to be largely avoided and also thrombus formation prevented. For this purpose the invention provides a smooth coating of hydrophilic ion conducting plastic for the electrode, comprising at least on the surface thereof, body and/or blood compatible material. The carbon electrode according to the invention serves in particular as a stimulus electrode, preferably in cardiac pacemakers.
Claims4
An implantable carbon electrode comprised of an electrically conductive electrode body and an electrode head, said electrode adapted for contact with an insulated lead-in cable, wherein at least the surface of said electrode head comprises a material selected from the group consisting of glass carbon and pyrolytic carbon which has been superficially activated to present a microporous surface, and wherein the surface of said electrode is provided with a smooth coating consisting of a hydrophilic, ion-conducting plastic having at least a surface thereof comprised of a body and/or blood compatible material.
