Abstract
The present invention is an apparatus and method for making a polymer patterned electrode for cardiac pacing and sensing. The electrode surface includes a polymer overlayed on an electrode. The polymer layer is patterned to form an electrode surface consisting of a polymer and a conductive metal surface. The electrode can be made of a high or low impedance electrode by changing the conductivity of the polymer. Furthermore, the electrode surface texture can be optimized with a micro pattern that may enhance the biocompatibility. The polymer may be conductive or insulative.
