摘要
An implantable electrode array for a cochlear implant has an array trunk that extends along a center axis from an insertion opening in an outer surface of a patient cochlea into the scala tympani. An apical section extends along the center axis from a distal end of the array trunk and a basal branch is separate from the array trunk and extends back from the distal end of the array trunk towards the insertion opening. The apical section follows along an outer lateral wall of the scala tympani during surgical insertion to attain a final insertion position towards the outer lateral wall in an apical portion of the scala tympani beyond a first basal turn of the cochlea. The basal branch attains a final insertion position towards an inner modiolar wall by the first basal turn of the cochlea with the basal branch stimulation contacts facing the inner modiolar wall.
