How the Osia® Implant works

The Osia® System features a powerful implant that sits under the skin and is designed to help you hear and communicate.

  • The benefits of active OS implants

The Cochlear™ Osia® System, the world’s first and only active osseointegrated steady-state implant (OSI) system, uses digital piezoelectric stimulation to send sound directly to the cochlea. It can help those with conductive or mixed hearing loss or single-sided deafness by using bone conduction technology that has not been used for this type of system before - piezoelectric stimulation. The advantages of piezoelectric stimulation include enhanced durability and improved hearing at high-frequencies that are critical for understanding speech.


How does an active OS implant work?

Active osseointegrated steady-state implants (OS implants) use the principle of bone conduction to bypass the damaged or missing parts of the outer or middle ear. However, unlike traditional bone conduction solutions, OS implants deliver the sound vibrations using digital piezoelectric stimulation through the transducer (the part that creates vibrations) located completely under the skin.

An active OS implant system includes the following main components:

  • External sound processor that captures sound in the air - the Osia® 2 Sound Processor is lightweight, durable and features state-of-the-art connectivity technology.
  • Internal implant that is placed under the skin and includes our Piezo Power™ transducer that is designed to deliver long-term performance and durability.1

Together, these components bypass the part of the ear that isn't working and send vibrations to the inner ear where they are sent to the brain and interpreted as sound.

Will you benefit from an active OS implant?

Research has shown that an active osseointegrated steady-state implant may help you or a loved one:2-5

  • Improve your understanding of speech in quiet and in noisy environments
  • Hear better, even in noise
  • Enjoy improved sound quality (compared to hearing aids) by bypassing the damaged part of the ear to reduce the amount of amplification needed to hear better

Try a bone conduction solution, then decide

You have the opportunity to try a Cochlear™ bone conduction solution before deciding whether to get an implant. Make an appointment with a Hearing Implant Specialist and they will be able to advise you if you may benefit from a bone conduction solution. Find one today.
