Miniature implantable array and stimulation system suitable for eyelid stimulation

摘要

An implantable miniature eyelid electrode apparatus that causes a paralyzed eyelid to close or open by passing an electrical stimulating current to a nerve or muscle, is comprised of a longitudinally flexible, nonconductive body containing electrodes that pass an electrical signal to the nearby nerve or muscle, which closes or opens the eyelid. The apparatus is electrically actuated by a source that may be located remotely from the apparatus. The electrical signal passes along wires from the source to the apparatus. The apparatus is biocompatible with the environment in the living tissue and is electrically insulated from the surrounding tissue, except where the electrodes contact the living tissue. The apparatus is very small and is not obvious to visual inspection when implanted.
