Abstract

Methods of delivering optical stimulation to a target tissue from an optical stimulation device are provided. One method comprises sensing a temperature at the optical stimulation device or proximate to the optical stimulation device, and adjusting the delivery of light to the target tissue based on the sensed temperature. Another method comprises delivering the light to the target tissue with an optical light guide and sensing bioelectric signals with a sense electrode, wherein the optical light guide and the sense electrode each comprise a material that produces substantially no induced current in an electromagnetic field. Another method comprises delivering light from a light source of an optical stimulation device to a window of the optical stimulation device, delivering the light from the window to an optical light guide optically connected to the window, and delivering the light to a target tissue via the optical light guide.
