Osia 2
NewPowerful, clear sound beneath the skin — no visible abutment
Osia 2 (model OSI200) is the newest active osseointegrated sound system from Cochlear. The piezoelectric Osia OSI100 implant sits fully under the skin and converts the signal into vibrations sent straight into the bone, so the skin stays intact. The external sound processor attaches by magnet over the implant to deliver strong, clear sound.
