Cochlear’s fully implantable middle ear implant system.

Power to hear. Night and day.

The fully implantable Carina® 2 System gives you the freedom to live your life your way, 24 hours a day, 7 days a week. And unlike a hearing aid, you can't lose it, drop it or forget it.

Unique technologies

  • Totally implantable microphone (TIM): Cochlear's unique TIM collects and processes sound without any external device.
  • Invisible digital signal processing (iDSP): designed to optimise hearing performance in invisible mode, by minimising body noises and using adaptive feedback cancellers.

Easy-to-use accessories

  • Charging System: The rechargeable battery gives you up to 32 hours of hearing on a single charge. Charging your battery takes about 40 minutes1,2 from an external charger coil placed over the device.
  • Remote control: You can switch the implant on and off, change program and adjust the volume – to give you a more personalised hearing experience.

Hear well in different environments

"Based on my two years' experience with [The] Carina [System], I fully recommend it. It has completely changed my life."

- Alexandre, Cochlear™ Carina® System recipient

Optional Button® audio processor

You can also use the Carina 2 System with the optional Button® Audio Processor. This pocket-sized processor gives you extra volume when you need it, like in a noisy work meeting or with friends at a restaurant.

Hearing all the time

"[The] Carina [System] has made communicating less tiring. I can focus on the content of the conversation so the communication is more fluid and faster, without interruptions."*

- Mariana, Cochlear™ Carina System recipient
