The Cochlear™ Nucleus® Profile Series C1632 Cochlear Implant

The Cochlear™ Nucleus® Profile Series C1632 cochlear implant, featuring fine near-cochlear axis electrodes, stands as the latest generation of cochlear technology developed by Cochlear Ltd. This groundbreaking device advances the foundation laid by the previous-generation Cochlear™ Nucleus® Profile CI512 system. Cochlear implants (such as the CI622 or C1632 models) are surgically implanted devices placed beneath the skin. They restore hearing by bypassing damaged inner ear hair cells in children and adults, delivering targeted electrical stimulation directly to the auditory nerve. The implant itself integrates a receiver/stimulator, coil, magnet, and multi-channel electrode array within a single unit. Crucially, unlike conventional implants, it operates without internal batteries or microphones. As shown in the diagram, during normal use, an external sound processor (like the Nucleus7 or Kanso2) captures ambient sound, processes audio signals, and transmits vital stimulation data and power across the skin to the implant. Precise alignment of the implant's magnet with the corresponding area on the sound processor ensures highly effective signal transmission. The cochlear implant then converts this digital information into precisely controlled electrical impulses, delivered through electrodes positioned within the cochlea. This stimulation elegantly bypasses damaged cells causing hearing loss, directly activating the auditory nerve to enable users to perceive rich, encoded sounds.
