An active electrode array adapted to be used with an implantable tissue stimulating prosthesis

摘要

An active electrode array adapted to be used with an implantable tissue stimulation prosthesis comprises a plurality of active electrodes (16). Each active electrode includes switching circuitry (16A, 19, 20) and a plurality of individual electrode contacts (19A, 20A). The individual electrode contacts may be individually activated by electrode control signals applied to the switching circuitry. <IMAGE>
