Cochlear™ Nucleus® System

Cochlear™ Nucleus® 6 System

How It Works:

There are two primary components to the Nucleus System: the sound processor and the implant.

  1. The external sound processor is worn behind the ear. It captures sound, then filters and processes the sounds, turning it into digital code.
  2. The sound processor transmits the digitally-coded sound through the coil on the outside of the head to the implant.
  3. The internal implant converts the digitally-coded sound into electrical impulses and sends them along the electrode array that sits gently in the cochlea (the inner ear).
  4. The implant’s electrodes stimulate the cochlea’s hearing nerve, bypassing the damaged cells that cause hearing loss, sending impulses to the brain where they are interpreted as sound.

Nucleus® Kanso™ Sound Processor

How It Works:

  1. The external sound processor is worn over the ear. It captures sound, then filters and processes the sounds, turning it into digital code.
  2. The sound processor transmits the digitally-coded sound through the coil on the outside of the head to the implant.
  3. The internal implant converts the digitally-coded sound into electrical impulses and sends them along the electrode array that sits gently in the cochlea (the inner ear).
  4. The implant’s electrodes stimulate the cochlea’s hearing nerve, bypassing the damaged cells that cause hearing loss, sending impulses to the brain where they are interpreted as sound.

Cochlear Nucleus Profile

Built on over 30 years of experience and developed in close collaboration with the world’s leading surgeons, the Profile Series is the thinnest cochlear implant platform. With a streamlined design, the Profile Series is easy to implant and gives patients the most discreet appearance. Combined with Cochlear’s unique pre-curled perimodiolar electrode, this is the ideal implant for maximizing hearing performance.

Cochlear Nucleus CI24RE

The Nucleus CI24RE Series has helped to improve hearing in more than 115,000* ears around the world and its reliability rating of 99% within 10 years, is the best in the industry. The world’s most implanted¹ and reliable cochlear implant.2-4

Electrode Portfolio

Slim Modiolar

World’s thinnest full length perimodiolar electrode

The Slim Modiolar Electrode is the world’s thinnest full length perimodiolar electrode9 designed for consistent scala tympani placement10 and sits closest to the hearing nerve to deliver optimal hearing performance11. It is reloadable, offers a smooth easy insertion and can be inserted through round window (RW), extended round window (ERW) or cochleostomy12. The Slim Modiolar electrode combines the unique benefits of a thin electrode with the perimodiolar positioning closer to the spiral ganglion cells.

Contour Advance

True innovation with the industry’s stylet based perimodiolar electrode.

The Contour Advance is the electrode that gets closer to the hearing nerve through its unique design. With the advance off stylet technique, insertion is achieved with minimal lateral wall trauma5 to maximize performance outcomes.6 Proximity to the spiral ganglion cell population has been proven to provide targeted stimulation and minimize physiological factors correlated to the distance from the modilous.7-8

 

Slim Straight

The industry’s thinnest full length electrode.

A soft tip combined with thin diameter, apical flexibility, and smooth lateral wall surface facilitates an easy single stroke insertion designed to protect the delicate cochlear structures.

 

Full-Band Straight

Ideal for abnormal cochleas.

As Cochlear’s first straight array with 22 active electrodes over a length of 17mm, the Full-Band Straight has found widespread use in patients with various types of abnormal cochlea.
