Abstract: A device, including an implantable electronic circuit integrated at least one of in or on a substrate, wherein the device includes a hermetic enclosure having a space therein, wherein the substrate forms at least a portion of the hermetic enclosure.

Abstract: The present invention relates to a method and apparatus for facilitating artificial vision using retinal electrical neuro-stimulation. Retinal ganglion cells are stimulated at two different sites in order to elicit better visual percepts. Primary stimulation is implemented at first site on the retina. Secondary stimulation is applied in the vicinity of the optic disc or optic nerve. The secondary stimulation modulates the signals elicited by the primary stimulation.

Abstract: An apparatus facilitating the delivery of electrical stimulation to physiologically excitable retinal nerve cells includes: (a), a receiver/decoder/stimulator comprising a semiconductor integrated circuit and other components hermetically sealed within a capsule, implanted and fixed within the eye of the patient such that it may receive power, and decode information from (b), an externally worn image processor/encoder/transmitter comprising an image detector, an image processor capable of translating the image into an array of discreet pixels of varying intensity, encoding the pixel information into a series of discreet data bursts representing the chosen current amplitude, pulse duration, stimulating electrode or electrodes, and reference electrode or electrodes, and transmitting this data to the receiver/decoder/stimulator through a tuned, inductive communication link such that the system may deliver controlled, charge balanced, diphasic, constant current stimulus pulses to (c), discreet metallic electrodes
