Abstract
An electrode system for an implantable cardioverter defibrillator. The electrode system includes a conductive structure which is physically and electrically connected to the housing or can of the implantable cardioverter defibrillator and is used as an electrode in combination with an existing implantable cardioverter defibrillator electrode or electrodes. The electrode system provides a therapeutically significant increase in the effective surface area of the implantable cardioverter defibrillator'"'"'s electrodes without requiring an additional header connection, feedthru, or cable.
