A stimulation electrode is described for a hearing impaired patient. An intra- fluid electrode branch (402) is immersed in cochlear fluid within an interior volume of a patient cochlea and has electrode contacts (403) for delivering a cochlear stimulation signal to adjacent neural tissue. An intra-modiolus electrode branch (404) penetrates through the cochlea and has one or more electrode contacts (405) for delivering a modiolus stimulation signal to cochlear nerve tissue within the modiolus of the patient.
