Abstract
An optical neurostimulation and detection system and method are disclosed. The system includes a medical device including an implantable body, and a stimulation controller that connects to the medical lead device and provides a light source. One or more light emitter modules of the lead body couple light signals of the light source into modulated light signals, and the modulated light signals are emitted through the one or more light emitter modules to stimulate neural cells and/or neural tissue of a subject. In a preferred embodiment, the light emitter modules include a surface acoustic wave (SAW) transducer that couples the light source into the modulated light signals. Such a system provides emitted light incident upon the neural tissue of a much higher resolution than current systems and methods and can provide long-term implantation with fewer side effects and less tissue damage than current systems and methods.
