A cochlear implant electrode arrangement is described that prevents post-surgical retraction of the electrode array from the cochlea. The arrangement includes an electrode lead that carries cochlear stimulation signals from an implanted signal processor, through an oval shaped posterior tympanotomy opening in the facial recess of a patient, to an electrode array implanted in a cochlea of the patient. A retraction limiter slides over the electrode lead through the posterior tympanotomy with projection arms aligned along the long diameter of the posterior tympanotomy, then is rotated to align the projection arms along the short diameter of the posterior tympanotomy, and secured to the electrode lead so that the projection arms prevent post-surgical retraction of the electrode lead back through the posterior tympanotomy.

An insertion system for inserting an implantable electrode carrier includes an insertion instrument having a housing with a proximal end and a distal end, and a vibration generator coupled adjacent to the housing. The proximal end is configured to hold the implantable electrode carrier. The vibration generator is configured to generate vibrations in at least a portion of the electrode carrier.
