Cochlear™ Nucleus® Sound Processor Portfolio: Small, Simple and Smart


Cochlear's sound processors are the smallest1 and the lightest1 in the industry. Some patients prefer a processor that sits on the ear, while others prefer a more discreet off-the-ear solution. Either way, this means more comfort, discretion and wearing time for all patients.1


Cochlear’s research has shown that some patients are comfortable controlling the settings on their sound processor, while others simply want to put their device on and forget about it. Whichever device they choose, you can be sure that with SmartSound® iQ* with automatic SCAN and dual microphone directionality your patients will hear their best.2,3


Your patients can connect to the people they love and the world around them, with Cochlear’s exclusive technology. The Nucleus™ 7 and Kanso® Sound Processors establish a clear and secure connection to Cochlear True Wireless™ devices without the interference, signal drops or additional weight of neck-loops or FM systems.

Cochlear™ Nucleus® 7 Sound Processor


Nucleus 7 is the world’s first and only Made for iPhone4 cochlear implant sound processor. First for iPhone®, First for Android™7 : the Nucleus Smart Apps allows recipients to control and monitor their sound processor with their smartphone.


Each patient is unique and their hearing solution should be too. With Nucleus 7, your patients can hear their way with the world's smallest and only Made for iPhone cochlear implant sound processor.


With Nucleus 7, recipients can stream sound from a compatible Apple®4 device directly to their sound processor, control and manage their settings, using their Apple or Android™ smart phone, track their data and locate a lost processor. With dual microphones and Cochlear’s most advanced sound management system – SmartSound® iQ* with SCAN – Nucleus 7 helps recipients hear their best even in noisy environments.3 In addition to the automatic features of SCAN, the Nucleus 7 Sound Processor features ForwardFocus**, a clinician-enabled, user-activated feature within the Nucleus Smart App which attenuates background noise, so you can be confident your patients are hearing their best.

*SNR-NR and WNR are approved for use with any recipient ages 6 years and older, who is able to 1) complete objective speech perception testing in quiet and in noise in order to determine and document performance 2) report a preference for different program settings. SCAN is FDA approved for use with any recipient age 6 years old and older, to be used at the discretion of the recipient/parent/caregiver.
**ForwardFocus can only be enabled by a hearing implant specialist. It should only be activated for users 12 years and older who are able to reliably provide feedback on sound quality and understand how to use the feature when moving to different or changing environments. It may be possible to have decreased speech understanding when using ForwardFocus in a quiet environment.



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.

Implant Portfolio

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%8 within 10 years, is the best in the industry. The world’s most implanted8 and reliable cochlear implant.8-11

Electrode Portfolio

Slim Modiolar

World’s thinnest full length perimodiolar electrode

The Slim Modiolar Electrode is the world’s thinnest full length perimodiolar electrode12 designed for consistent scala tympani placement13 and sits closest to the hearing nerve to deliver optimal hearing performance14. It is reloadable, offers a smooth easy insertion and can be inserted through round window (RW), extended round window (ERW) or cochleostomy15. 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 trauma16 to maximize performance outcomes.17 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.14,18


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.
