Publication number: 20110144733Abstract: An electrode for a cochlear implant for implantation in a cochlea of a patient, the electrode having a first side that is curved in a lateral dimension so as to substantially conform to a side wall of a scala upon implantation of the electrode into a cochlea and a second side that is shaped so as to preserve a natural acoustic pathway within the scala upon implantation of the electrode into the cochlea. In one example, opposing ends of the electrode taper off in cross section. In another example, the fluid contact side is concave. In a further example, the electrode is one of crescent-shaped, oval shaped, and semi-circular in cross section.
