Osia® implant

The Osia OSI200 implant

The Piezo Power transducer is made of piezoelectric layers that expand and contract to send vibrations through to the cochlea. The piezoelectric effect is the ability of certain materials to generate an electrical charge from mechanical stress, or in reverse, to generate vibrations from an electrical charge.

The advantages of the Piezo Power transducer include its sensitivity at high frequencies important to speech and its suitability for implantation where there is a high demand on power, size and reliability.¹ Unlike electromagnetic transducers first designed for external use, the Piezo Power transducer has no movement between parts that can cause wear over time.² Furthermore, the OSI200’s unique Piezo Power™ transducer has a digital link that transfers 100% of the signal* with minimal risk of interference.³

The Osia OSI200 Implant is designed to allow for a straightforward surgical procedure. The monolithic design is intended to make coil insertion easy and ensure there is no coil migration. Its thin profile and fixation to the BI300 Implant minimizes the need for extensive bone removal and risk for dura exposure. A pre-operative CT scan is not required.
