Digisonic® SP ABI brainstem implant

In cases where hearing loss is accompanied by large lesions in both cochleae, including deterioration of the auditory nerve, a brainstem implant is typically recommended. This can restore a degree of hearing and enable communication.

The Digisonic® SP ABI brainstem implant is designed to overcome severe to total deafness for people suffering from major damage to the cochleae or to the auditory nerves, which prevent cochlear implantation.

This includes people with:
Major cochlear malformation
Complete cochlear ossification
Fracture of the petrous pyramid
Axonal neuropathy
Tumours on the auditory nerves, such as neuromas
Complete obliteration of both auditory nerves

Improved hearing for better quality of life

With the Digisonic® SP ABI brainstem implant, users receive auditory sensations that can facilitate communication and improve quality of life1,2. It comes with an array of 15 surface electrodes that are attached to the cochlear nuclei of the brainstem. Depending on the signal processed by the external sound processor, each electrode stimulates a different region of the brainstem so that patients can perceive a wide range of sounds. The Digisonic® SP ABI brainstem implant can be used with the Saphyr® neo collection sound processor.

Part of the Digisonic® SP range

The Digisonic® SP ABI holds some identical and competitive characteristics as the Digisonic® SP cochlear implant: a monobloc and compact receiver that integrates a unique fixation system. The quality of the chosen materials makes this device highly reliable. It is also compatible with MRI tests at 1.5 Tesla, commonly used in clinical practice.
