Cochlear implant using optical stimulation with encoded information designed to limit heating effects

摘要

Method and apparatus for optically and electrically stimulating neurons of auditory nerve pathways of a person to provide auditory sensations for the person, including generating a plurality of pulsed light signals having one or more successive pulses, delivering the plurality of pulsed light signals to one or more auditory nerve pathways of the cochlea of the person, and selectively controlling the plurality of light signals to optically stimulate and trigger nerve action potentials (NAPs) in the one or more auditory nerve pathways. In some embodiments, the present invention also includes one or more electrical stimulation electrodes used to stimulate the low-frequency portions of the auditory nerves.
