The EAS Hearing Implant System

Electric Acoustic Stimulation (EAS) is designed to fit the unique needs of individuals with partial deafness. EAS combines the advantages of acoustic amplification and cochlear implant technology in one system. The system consists of both an internal and an external component.
 
 

INTERNAL
Implant
The implant, either the SONATA or PULSAR, is surgically placed under the skin. It consists of a housing for the electronics, a receiving antenna and a magnet that holds the coil in place behind the ear. An especially soft FLEX electrode is gently inserted into the cochlea during surgery.
 

EXTERNAL
Audio processor
The DUET 2 Audio Processor is worn behind the ear. It consists of a control unit and a battery pack, an ear hook for dedicated acoustic amplification, and a coil that transmits information through the skin to the implant.
