Retinal prosthesis
The invention is a retinal prosthesis with an improved configuration mounting necessary components within and surrounding the eye. The present invention better allows for the implantation of electronics within the delicate eye structure. The invention provides for less height of the part external to the eye by mounting a receiver coil around an electronics package.
1. A retinal prosthesis comprising:
an electrode array and integral demultiplexer suitable to be mounted internal to a sclera and in close proximity to a retina;
an electronics package encasing electronics suitable to be outside the eye;
a cable suitable to pierce the sclera electrically coupling said electrode array to said electronics package; and
a coil electrically coupled to said electronics.
2. The retinal prosthesis according to claim 1 , wherein said electrode array and said demultiplexer are formed on a common substrate.
3. The retinal prosthesis according to claim 1 , wherein said demultiplexer is deposited on a thin film substrate.
4. The retinal prosthesis according to claim 3 , wherein said electrode array and said demultiplexer are deposited on a common thin film substrate.
5. The retinal prosthesis according to claim 4 , wherein said electrode array, said demultiplexer, and said cable are deposited on a common thin film substrate.
6. The retinal prosthesis according to claim 1 , further comprising:
a camera for collecting a video image;
a video processor coupled to said camera for processing said video image; and
a primary coil coupled to said video processor for transmitting said video image into a body and to said coil.
7. The retinal prosthesis according to claim 6 , wherein the coil is approximately the same shape and size as the primarily coil.
8. The retinal prosthesis according to claim 1 , wherein the coil is aligned with a lateral side of the sclera.
