How does an Advanced Bionics cochlear implant work?

Your child’s hearing loss means that a portion of the ear is not functioning appropriately. Often, a hearing aid can compensate for the loss by making sounds louder and easier to hear. However, when the loss is too severe, making sounds louder may not be enough. 

Cochlear implants are the standard treatment for children with severe-to-profound hearing loss. These amazing devices make sounds clearer and easier to understand by bypassing the damaged portion of the cochlea and sending sound directly to your child’s hearing nerve.


The Advanced Bionics microphones pick up sounds at the opening of the ear canal for the most natural listening experience.


The sound waves are converted into detailed digital signals by our sound processor.


Our headpiece sends the digital signals to the cochlear implant and electrode array in the inner ear.


The electrode array stimulates the hearing nerve.


The hearing nerve sends impulses to the brain, which interprets them as sounds.

The transformative benefits of a cochlear implant.

A cochlear implant is a life-changing decision, as your child may:

  • Have the potential to develop normal hearing, speech, and language skills.
  • Be able to enjoy listening to music, watching television, and holding conversations over the phone.
  • Gain a sense of inclusion, allowing them to socialize and connect with friends and family.
  • Build the skills and confidence that will help them as they mature and attend school and begin working.

HiRes Ultra 3D Cochlear Implant

Our HiRes™ Ultra 3D cochlear implant is designed for your child to get the most out of every listening experience—whether it’s hearing music, the sounds of the world around them, or their teacher’s voice in a noisy classroom.

Our implant delivers the proven benefits of clearer speech1 and a broader range of sound,2 and is designed to exceed industry standards for impact resistance3 so your child can enjoy life’s adventures without limits —from the playground to the playing field.


Your child’s implant is made up of several components: the electrode array, the electronics package, the communication link, and the multi-magnet assembly.


Designed to be inserted into your child’s cochlea,4 our electrodes deliver 120 different pitches, more than any other implant, to help your child understand speech and enjoy music.5


Provides a reliable connection to the external headpiece. The HiRes™ Ultra 3D implant ensures your child can experience a hassle-free MRI, even at powerful 3T scans. 

Gentle on the inner ear.

Ensuring your child has a positive implantation and activation is our top priority. That’s why we offer two different electrodes (HiFocus™ SlimJ and HiFocus™ Mid-Scala) that surgeons can choose from, based on what’s best for your child’s unique anatomy. Both electrodes are designed to protect the delicate cochlear structures and provide complete coverage of the cochlea for full-spectrum sound.


Your child will have their implant for life, so our implants are designed to keep up as technology advances for decades to come. By upgrading your child’s processor, they can enjoy new listening features and expanded capabilities without needing to change the implant.

Hassle-free MRI.

No one wants to think about needing an MRI in the future. Which is why we’re keeping this in mind for you. Our sophisticated Ultra 3D multi-magnet assembly ensures your child will not need extra surgeries before and after an MRI examination. This means one less thing for you to worry about.

The HiRes Ultra 3D has been awarded MedTech’s Breakthrough Award 2019 for Best Overall Medical Device Solution.
