Abstract:
A biocompatible, micro-fabricated ribbon cable is described in which at least one set of conductors diverges laterally into a bypass wing that forms an aperture through the ribbon cable. The bypass wing is folded in a line through the aperture and over a central portion of the ribbon cable, resulting in a ribbon cable with a narrow, stacked region. The narrow region can fit through small incisions in membranes, such as through an incision in a sclera of an eyeball. The ribbon cable can have an integrally-formed electrode array for attaching to a retina of an eyeball and other electronics for sending signals to the electrode array.
