An active implant means the working part, a vibrating transducer, is surgically placed under the skin, attached to the skull. A sound processor is worn on the outside of the head, behind the ear, held in place by a magnet.
The internal implant consists of a coil and a magnet, an electronic package and a small vibrator. These are implanted under the skin. Externally, a sound processor is placed on the skin using a magnet to hold it in place. The processor has microphones to pick up the sound, and a replaceable battery.
The following active devices are currently available:
MED-EL Bonebridge
The Bonebridge is suitable for patients with a mild hearing loss and can be used for patients from 5 years of age. The external processor is called a Samba 2 (formerly Samba).




The Samba 2 cannot stream directly to iPhone or android, but MED-EL offer an accessory which is worn around the neck called a Samba 2 Go which then functions to stream media/calls from the mobile phone to the processor.
