1. An implantable electrode array comprising a carrier that is insertable into a cochlea of an implantee, the carrier having a proximal end and a distal end and comprising:

  • a first layer of a resiliently flexible material and having an inner surface and an outer surface;

    at least a second layer of a resiliently flexible material and which at least partially overlies the outer surface of the first layer; and

    a plurality of electrodes supported within the carrier at respective spaced locations in a region between the proximal end and the distal end of the carrier, at least one of the electrodes having a surface that is at least adjacent the inner surface of the first layer;

    wherein the carrier is formed in a second configuration in which the array can apply tissue stimulation to the cochlea and is manipulable to a first configuration that allows the carrier to be insertable into the cochlea of an implantee.
