Cochlear™ Nucleus® Implants

The internal cochlear implant is made of up two primary components: the implant receiver and the cochlear electrode array.

  1. The implant receiver, placed just under the skin, converts the digital sound signals picked up from the external sound processor and sends them down the electrode.
  2. The electrode is inserted into the cochlea, stimulates the cochlea through “contacts” and sends impulses directly to the hearing nerve where they are perceived as sound.
Cochlear is up to 11 times more reliable than other manufacturers

Cochlear is #1 In Reliability

When considering a cochlear implant, you want to know all the facts. You want to feel confident that you are choosing the most reliable cochlear implant available.

Electrode Portfolio - Designed for Performance

The natural curves of the cochlea come in all shapes and sizes which is why we offer a wide range of electrode arrays so your surgeon can pick the best one for your level of hearing loss and to give you the greatest sound resolution and coverage in your inner ear.1-3

Key features of our electrode array portfolio:

  • The most active electrode contacts in the industry -22 contacts - to provide the full spectrum of sound*
  • Perimodiolar electrodes that are placed closest to the hearing nerve for an optimal hearing performance
  • Thinnest electrodes designed to preserve the delicate cochlear structures*

*Measurements according to manufacturers specifications collateral.

An Implant Designed Just For You

In addition to our wide range of electrode arrays, we also offer implants that are designed to last a lifetime. Our newest implant, the Nucleus® Profile Implant, further expands on our history of innovations that provide surgeons with more choices to fit your needs for your best hearing performance. The Profile Implant is the thinnest implant4,6 and is designed to follow the curvature of the head for a better cosmetic outcome and added comfort. It is also very impact resistant for added peace of mind.*

*Resistant against external impact up to 2.5 joules.
