Abstract

A device for the re-animation of the paralyzed face including electrodes implanted in muscles on the healthy side of the face, said electrodes sensing contractions and sending signals to a microprocessor, which in turn processes said signals and re-transmits them to other electrodes implanted in the counterpart muscles in the paralyzed side of the face, thereby stimulating said counterpart muscles to contract. Also, a method for treating the paralyzed face in which some exigency requires a delay before said device can be installed, including periodically electronically stimulating the muscles on the paralyzed side of the face, thereby preventing atrophy for whatever time span is required. In another embodiment an electromagnet implanted in the bone below the eye on the paralyzed side of the face receives signals from the non-paralyzed side of the face, which energize a current causing the electromagnet to pull the eyelid shut, said eyelid having ferrous material implanted therein.

Claims
