Patent ID: 8639344

Claim:
A flexible circuit electrode array, configured for implantation on an approximately spherical retina in an eye having a radius of curvature, comprised of electrodes that comprise an electrode array, said flexible circuit electrode array configured to electrically connect with an electronics package that is remote from said array, comprising: a polymer base layer forming a flexible circuit bond pad portion, flexible circuit cable portion and a flexible circuit electrode array portion; metal traces, deposited on said polymer base layer, electrically coupled to said bond pads and said electrodes, said electrodes configured to stimulate neural tissue; said flexible circuit electrode array portion and said metal traces embedded in a body comprised of an electrically insulating material said body forming said flexible circuit electrode array to have an approximately spherical pre-curved surface to substantially conform to the approximately spherical retina; and said body comprised of said electrically insulating material that is softer than said polymer base layer; and said flexible circuit bond pad portion adapted to directly connect to an electronics package.
