Cochlear Implants
SYNCHRONY Cochlear Implant System

A cochlear implant (CI) system helps to restore the sense of hearing for individuals with severe-to-profound sensorineural hearing loss. For individuals with this type of hearing loss, hearing aids provide little or no benefit.

A CI is the only medical device capable of replacing a sense. It works by bypassing non-functioning parts of the inner ear and providing electrical stimulation directly to nerve fibers in the cochlea. A CI system consists of two parts: an externally worn audio processor, which sits comfortably behind or off the ear, and an internal cochlear implant, which is surgically placed just under the skin.

Our incredibly soft, flexible electrodes are designed to protect the delicate nerve cells of your inner ear. Protecting your cochlea enables your implant to deliver the best benefit, both now and in the future.


Complete Cochlear Coverage

To hear the most natural range of sounds, you'll need an implant electrode that's long enough to cover the whole cochlea. We offer the longest, most flexible electrodes available, making our electrodes the only choice for Complete Cochlear Coverage.

* Fine-structure coding is not indicated for pre-lingual children in the USA.
