Cochlear: Number one for reliability

Cochlear™ Nucleus® Implant Reliability Report.

Reliability Report 2017

A cochlear implant is with you for life.

High implant reliability means greater patient satisfaction and less risk of additional surgery. When considering a cochlear implant, it's important that you have access to the latest data on short-and long-term reliability, including success and failure rates for both adults and children.

Cochlear's implants are the most reliable1 in the industry.*

We meet and report against the independent global standards for implant reliability2-4. We publish data of every implant generation, past and present, and make this information available to surgeons and audiologists around the world.

Reliability Report 2017

And the results in our 2017 Reliability Report are clear:

  • Cochlear™ Nucleus® Profile Series – 99.94% reliability within three years in the market.
  • Cochlear Nucleus CI24RE – 99% reliability within 12 years in the market.

No other implant company meets the global standards for reliability reporting2-4 and no other company can match Cochlear's record for implant reliability5-7.
