Claim:
1. A cochlear implant electrode comprising: an active base section with a front surface configured to lie against an inner modiolar wall of a scala tympani in an implanted patient and a back surface facing a center of the scala tympani; a plurality of electrode contacts on the front surface of the active base section configured to face the inner modiolar wall to deliver electrode stimulation signals to nearby modiolar neural tissue; a passive apex section with a front surface without electrode contacts configured to lie against an outer lateral wall of the scala tympani and a back surface facing the center of the scala tympani; and a U-shape transition bend section at an apical end of the active base section bending in a reverse direction and transitioning into a basal end of the passive apex section whereby the back surface of the passive apex section lies adjacent to a back surface of the active base section when the electrode is implanted in the patient.
