摘要:
A pyrode converts near-infrared light to an electric field that wirelessly stimulates nerve tissue at one or more locations in a host body, such as in a retina, a cochlea, a heart axon, or a motor nerve. Partial vision is restored when a pyrode implanted in a retina is activated by a scanner. Only the pyrode is implanted in the retina, whereas all other components remain external to the host body. Nerves other than the retina are stimulated by a pyrode coupled to a source of photonic energy by an optical conduit. In one preferred embodiment the photonic energy source is implanted in the host body. In another preferred embodiment, photonic energy from an external source is piped to the pyrode by way of an optical conduit via a percutaneous lead. Electrooptic diverters enable sequential activation of multiple pyrodes branched from a main conduit.
