| abstract |
A visual prosthesis apparatus for operative insertion in the optical pathway to the brain of an individual who has an eye which is blind or partially blind. The prosthesis apparatus utilizes a video camera capable of generating video signals in response to the viewing of an image. The apparatus also includes a prosthesis device or so-called insert for insertion in the eye socket in place of the diseased or damaged eye. A cable is provided for electrically connecting the output of a video camera to the insert and for delivering video signals over individual conductors in this cable to the insert. An optical nerve connecting assembly is located in the insert and has terminals for connections to the individual conductors of the cable and to the optical nerves. In this way, there is an electrical connection between each conductor and an optical nerve through the nerve connecting assembly for delivering the individual video signals to the brain. A method of using this prosthesis is also disclosed. |
