DOUBLE BRANCH COCHLEAR IMPLANT ELECTRODE FOR PENETRATION INTO THE NERVE TISSUE WITHIN THE MODIOLUS

摘要

A stimulation electrode is described for a hearing impaired patient. An intra-fluid electrode branch is immersed in cochlear fluid within an interior volume of a patient cochlea and has electrode contacts for delivering a cochlear stimulation signal to adjacent neural tissue. An intra-modiolus electrode branch penetrates through the cochlea and has one or more electrode contacts for delivering a modiolus stimulation signal to cochlear nerve tissue within the modiolus of the patient.
