Abstract: The present embodiment is an implantable device capable of controlling cochlear implant electrode insertion and positioning. The embodiment uses an implanted mechanical positioning unit to advance position and monitor an electrode array. The device can be controlled via an external controller to reposition or advance an electrode array at any point after implantation with no surgical re-intervention. A cochlear implant electrode array whose position can be advanced and modified over time to best fit a patient's evolving hearing pattern would improve functional outcomes and significantly expand the candidacy range for cochlear implantation to include patients with substantial residual hearing.
