Abstract

Medical device implants for stimulating the nervous system of a recipient are disclosed. Embodiments include a cochlear implant with electrodes for delivering charge to the cochlea of the recipient and stimulation circuitry for delivering the charge to the electrodes. The medical devices include a transfer line which carries power and/or communication signals, the transfer line being in contact with tissue of the recipient when the medical device implant is implanted. A leakage capture conductor and/or sensing electrode is located or locatable proximate the insulated conductor.
