Learn about the innovative features & benefits of the Nucleus® 6 Implant System

The Nucleus® System, everything we've learned over 30 years makes it simply smarter

The Nucleus® System is the latest in a long history of Cochlear™ innovations, spanning over 30 years. The world has never seen a system this powerful. Or this smart. Cochlear implants can help bring back the sounds you're missing. With cochlear implants, you may once again enjoy conversations with friends and family, talk on the phone, hear the sounds of nature or see your child's face light up as they hear your voice for the very first time. Cochlear implants can seem like a hearing miracle.



Improve sound clarity and speech understanding with Hybrid™ Hearing*

Cochlear™ Hybrid™ Hearing uses acoustic amplification to improve the hearing you may have after surgery, while taking advantage of cochlear implant technology to restore access to the hearing you’re missing. The result can be improved sound quality and speech recognition.

*The Acoustic Component should only be used when behavioral audiometric thresholds can be obtained and the recipient can provide feedback regarding sound quality




Enjoy True Wireless™ with no strings attached

The Nucleus® 6 Sound Processor can introduce you to a whole new wireless world. You can watch TV, talk on your smartphone and hear speech and conversation - all without the constraints of wires. Cochlear™ is the first company that provides a truly wireless experience and uses the same 2.4GHz wireless protocol that Bluetooth® and Wi-Fi devices depend on. That means a clear, secure connection without interference and signal drops.

An implant designed just for you

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

  1. The implant receiver/stimulator, 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.

As the creators of the first multichannel cochlear implant, we understand the need for advanced options of implants and electrode arrays. With hearing performance in mind, we continue to innovate our technology to improve upon our implant and electrode design. Examples of our innovations are our perimodiolar electrodes that are placed closest to the hearing nerve for an optimal hearing performance, including our Cochlear™ Nucleus® Slim Modiolar Electrode.

In addition to our range of electrode arrays, we also offer the Nucleus® Profile Implant - the thinnest implant available1-3. The Profile contours to the curvature of the head for added comfort and is very impact resistant. The Nucleus Profile further expands what is the industry's largest cochlear implant portfolio and provides surgeons more choices to fit your needs.


Cochlear is #1 in reliability4-9

When you’re considering a cochlear implant, you want to know all the facts, especially when it comes to the reliability of the implant you are choosing. The fact is, our Nucleus CI24RE cochlear implant is more reliable than anything else available today.4-6

What’s more important is reliability over time. We design our Cochlear Implants to last a lifetime, and our long-term reliability records reflect that.

  • Our Nucleus CI24RE Cochlear Implant boasts a 99.2% reliability rating at 9 years 4
  • Most trusted and chosen implants with over 285,000 devices implanted worldwide4

All cochlear implant manufacturers have demonstrated the capability to build a reliable implant for one year, but only the Nucleus Implant has demonstrated a strong reliability rating over time.4


A sound processor that adapts to your world – Automatically

Every place is different, with different sounds. One minute you could be walking down a quiet street and the next, you’re stepping into a crowded restaurant. You’re constantly moving into different listening environments, and you want your sound processor to adapt to all of them – effortlessly. Our SmartSound® iQ* and dual-microphone technologies are designed to do just that.

The Nucleus® 6 Sound Processor uses dual-microphone zoom technology to help filter out background noise to optimize your hearing experience. The synchronized microphones work together to reduce sound from behind and to the sides so you hear more of what you want.

The Nucleus 6 Sound Processor has the world’s first Scene Classifier in the cochlear implant industry that automatically scans your surroundings and identifies the listening environment as one of six scenes. SmartSound iQ then adjusts the setting for that scene to provide you optimal hearing for that situation without the need for manual adjustments to the sound processor. It’s this advanced technology that makes the Nucleus 6 Sound Processor simply smarter.

*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.


Safety matters with MRI

Magnetic Resonance Imaging (MRI) is a common medical imaging procedure. MRI machines use a powerful magnet to provide detailed images of a person’s internal organs and tissue. Because of this powerful magnet, 97% of radiology professionals surveyed do not recommend MRI scans for patients with magnets in their body.10

In fact, 85% of radiology professionals agree they have an alternate diagnostic tool for patients who cannot undergo an MRI due to having a device or implant with a magnet.10 However, on the rare occasion that you may need an MRI, you can have peace of mind that Cochlear™ Nucleus® Implants are compatible with an MRI of 3.0 Tesla with the magnet removed. If it is desired to keep the magnet in place, Nucleus Implants are also approved for an MRI of 1.5 Tesla with the magnet in place, using our MRI Kit.

There are risks in keeping the internal cochlear implant magnet in place during an MRI which is why we believe the gold standard is to remove the magnet.

Risks involved with leaving the magnet in during an MRI include:

  • Pain or discomfort during the MRI procedure11
  • Pulling or movement of the magnet underneath the skin11 which could put the placement of the internal electrode at risk
  • Reversal of magnet polarity or demagnetization11 requiring a procedure to replace the magnet
  • Decreased quality of the MRI image due to shadow that the implant magnet may cast on the desired area12

Because of these risks, we have designed our implants specifically for safe and easy magnet removal.

Cochlear Nucleus Implants are designed with the safety and comfort of the patient in mind, today and into the future. That’s why more people choose Cochlear than any other hearing implant company.13,14


Hear your best – In both ears

Hearing with both ears offers a clear advantage, especially when it comes to distinguishing where sound is coming from and understanding speech in noisy environments.

Depending on your degree of hearing loss, you may benefit from bimodal hearing, which is using a hearing aid in one ear and a cochlear implant in the other ear. Or, you may find it more beneficial to have a cochlear implant in both ears (bilateral cochlear implants). With both bimodal hearing and bilateral cochlear implants, you may find that understanding speech is much easier and that you’re able to enjoy a more complete hearing experience, especially in noisy environments.

For those individuals who have a Cochlear Implant in one ear and still receive benefit from a hearing aid in the other ear (bimodal hearing), Cochlear has partnered with GN ReSound to pioneer the world’s smartest bimodal hearing solutions with SMARTstream™ technology.


Whether you use a hearing aid, cochlear implants or a combination of the two, the Nucleus System can help you continue to experience the benefits of hearing with both ears for years to come.

A processor so smart, it can tell you where it's been

It can be hard to remember what happened yesterday, let alone the last month. With data logging, you don’t have to. It records exactly how your sound processor is being used every day. It fills in all the gaps, so your audiologist gets a more complete picture of your hearing experiences, and makes any necessary adjustments so you can hear your best.

For parents, the data logging functionality provides added confidence that your child is hearing their best at all times. For the first time ever, key information about your child’s Nucleus® System can be downloaded by your audiologist for evaluation. This is a minute-to-minute, comprehensive record that lets the audiologist know how your child is using the system and if it’s being used correctly, especially when you cannot be with them.
