Cortical Visual Prosthesis

摘要

The present invention is a visual prosthesis adapted for implantation in the brain, and more particularly with an electrode array adapted for implantation in the Calcarine Sulcus of the visual cortex. The electrode array of the invention has electrodes on each side and spaced appropriately for the Calcarine Sulcus and driven by an electronic circuit within a hermetic package small enough to be implanted with a skull.

主权项

1. A visual prosthesis comprising:
a flexible circuit and including a bond pad portion, and cable portion and an electrode array portion including stimulating electrodes on both side of the flexible circuit adapted to stimulate neurons in the Calcarine Sulcus region of the brain; a driver circuit driving stimulation signals on the flexible circuit, the driver circuit within a hermetic housing suitable to be implanted with a head; and a coil providing power and data to the driver circuit.
