A hearing implant reimagined
The Osia OSI300 is placed under the skin and works by bypassing damaged areas of the outer and middle ear, which sends sound directly to the inner ear. The OSI300 implant is attached to the BI300 which is Cochlear’s latest titanium implant featuring TiOblast™ surface technology. The BI300 implant is designed to promote faster and stronger integration to the bone (through a natural process known as osseointegration).
Piezo Power™ technology
The Osia System's Piezo Power™ transducer, in the OSI300 Implant, creates vibrations that are sent through the bone directly to your inner ear. One of the advantages of the Piezo Power transducer is its ability to vibrate at high frequencies1. This means that in the most difficult listening situations, like a noisy restaurant or a busy classroom, the Osia System helps you hear those sounds that bring clarity to speech understanding.
Lifetime testing shows that Piezo Power technology provides powerful and consistent performance over time.2
The power to hear more
The powerful transducer can help those with hearing loss up to 55 dB bone conduction thresholds. This means it can help address a range of hearing loss levels and can help you hear now as well as if your hearing loss gets worse over time.
"I’ve followed Cochlear for quite a few years, and I knew they had a great reputation. So, I was pretty confident. I’m a bit adventurous, so I thought, why not?"
- Adrian, Osia System recipient
Designed to implant, made to last
The Piezo Power transducer has a completely different design than traditional bone conduction transducers. The Osia System has demonstrated 99.64% reliability since it's release3, and accelerated lifetime testing has demonstrated consistent performance for the Piezo Power transducer over time.2
Significant improvement in hearing
We’ve tested the first generation Osia System in trials across multiple clinics around the world. After one year, people who received the new technology showed significant hearing improvements, even in noisy environments.4
Osia System users show a significant improvement in their ability to understand speech in quiet and in noisy environments.4
Designed for safe MRIs
Many people need an MRI scan at some point in their life. With the OSI300 Implant, you're able to undergo high-resolution MRI scans at 1.5 and 3.0 Tesla strength without having to worry about your implant.* Testing shows that the performance of the Piezo Power transducer remains consistent after MRI exposure.5
