LOW POLARIZATION COATING FOR IMPLANTABLE ELECTRODE

Title:

LOW POLARIZATION COATING FOR IMPLANTABLE ELECTRODE

Document Type and Number:

Japanese Patent JP2004261600

Kind Code:

A

Abstract:

To provide coatings for implantable electrodes such as pacing electrodes, neurostimulator electrodes, and electroporating electrodes and sensing electrodes.

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.
