Abstract
Official abstract text for this publication.
The present invention provides an apparatus that includes an infrared (IR) light source having two or more wavelengths (e.g., a relatively broad wavelength-profile light source and/or a light source with a plurality of relatively narrowband wavelengths), wherein the different wavelengths have different tissue-penetration depths. The IR light provides optical stimulation of nerves to generate nerve-action potentials (NAPs) in one or more individual nerve cells, and/or compound nerve-action potentials (CNAPs) in a nerve bundle. In some embodiments, the stimulation of NAPs and CNAPs is used to restore hearing. In some embodiments, the broad wavelength profile extends the physical volume of tissue that is stimulated, thus homogenizing the spatial light-absorption profile of the stimulation light used, e.g., for optical triggering of NAPs and CNAPs in the cochlea.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for optically stimulating a neural tissue in a cochlea of a person in order to trigger a compound nerve-action-potential (CNAP) response that evokes sensations for the person without damaging the neural tissue, wherein the neural tissue includes a plurality of neural tissue types at different tissue depths including a first type at a first tissue depth having a first optical-absorption coefficient at a first wavelength, a second type at a second…
