ABSTRACT:
An electrode in the form of a foil-like flexible, electrically insulating support member having nerve electrodes supported thereupon for implantation into the cochlea. The electrode establishes electrical communication to the acoustic nerves of the human ear, substantially in the area of the cochlea containing the auditory nerves pertaining to that part of the audible spectrum, which is relevant to the intelligibility of speech. The electrode is provided with two prongs and a shank, each prong having a length which corresponds to the length of the turn in the cochlea into which it is to be inserted during implantation and hence the two prongs are of different lengths. Further, each prong terminates in a bevelled pilot guiding member which guides each prong through its respective turn in the cochlea to thereby reduce damage to the auditory nerves. During implantation each prong passes through only a single turn of the cochlea and is prevented from gouging into the walls of the cochlea due to provision of the bevelled guiding member. The guiding member can be provided as a drop-shaped member secured to the end of each prong or by forming an eyelet in the distal ends of the prongs.
