Cochlear Nucleus Implants

We design Cochlear Nucleus Implants to give adults and children their best possible hearing performance for today and for the future.

Our industry leading cochlear implants are based on more than 40 years of research and innovation. Our devices are designed to suit the unique anatomy of the ear and give adults and children their best possible hearing outcomes.

The Nucleus Profile™ Plus Implant

With the Nucleus Profile Plus Implant, adults and children can have a routine 1.5 T MRI or high-definition 3.0 T MRI without removing its magnet. This means no additional surgery, no need to wear a bandage in the MRI machine, no waiting for a scan and, most importantly, no unnecessary time without sound.*

The Profile Plus Implant is built on the most reliable and thinnest implant platform18 in the world with a flexible coil designed to better fit the natural shape of the head. Its sleek, streamlined shape offers a more discreet appearance than other, thicker devices.

Nucleus Profile Plus Implant with Slim Modiolar Electrode

Designed for hearing performance

Our precision implants and electrodes are designed to give adults and children their best possible hearing performance – even in challenging listening situations.

Only Cochlear offers a thin, perimodiolar electrode with a shape that’s designed to fit the natural spiral of the inner ear. The Slim Modiolar Electrode* sits close to the hearing nerve, which means it can deliver electrical stimulation to the hearing nerve more precisely3-6 and efficiently.7,8

Studies show this leads to better hearing outcomes, including improved speech recognition and understanding in both quiet and noisy environments.9-13

Unmatched reliability you can trust

When deciding on a hearing implant for an adult or a child, we understand they want the best – for today and over time.

We meet and report against the independent global standards for implant reliability, publishing data for every implant generation, past and present.14-17

So, when choosing a Cochlear Nucleus Implant, adults and children can trust that they've chosen the most reliable in the world.18-20

Discover the importance of implant reliability.

The world's most chosen implants

With more than 475,000 registered Cochlear Nucleus Implants worldwide, when an adult or child chooses Cochlear, they're joining the largest community of cochlear implant recipients in the world.18-21

*Unless magnet removal is necessary to reduce image artefact. If you need an MRI scan of your head, your cochlear implant magnet may need to be removed because it will distort the scan image at any MRI strength. If your magnet does need to be removed, you can feel confident that the design of the Profile Plus Series Implant makes this as swift and straightforward as possible.
