Abstract:
1. A retinal prosthesis test device comprised of: an external image source producing a video image; a micro-cable for conducting the video through a patient's eye wall; an electronic chip for demultiplexing the video image into a two-dimensional (2-D) array of unit cells; a nanochannel glass electrode array hybridized to said 2-D array of unit cells with induim bumps and electrically connecting each unit cell to adjacent neural tissue; an external electronic circuit board generating a biphasic pulse applied globally to the unit cells through the micro-cable causing an electronic signal to be directed into a human eye retina wherein it is converted to an electrochemical signal and transmitted within the eye to a patient's optic nerve, whereby said device stimulates neural tissue via a conformal surface achieved by machining said nanochannel glass surface.
