Abstract
An electrode for a cardiac lead and method of making the same are provided. The electrode includes an electrode member and a coating applied to the electrode member. The coating is composed of an electrically insulating material and covers a first portion of the exterior of the electrode member while leaving a preselected second portion thereof exposed. The second or exposed portion enhances the impedance of the electrode, resulting in power savings and extended life spans for implantable stimulation and sensing devices. Exemplary materials for the coating includes diamond-like carbon and sapphire.
