Optical stimulation therapy
First Claim
1. A method for delivering optical stimulation, the method comprising:
- delivering light to a target tissue via an implanted optical stimulation device, wherein the implanted optical stimulation device comprises a therapy delivery module, the therapy delivery module comprising a light source and a controller that controls the light source to generate light;
sensing a temperature at the optical stimulation device or proximate to the optical stimulation device via a temperature sensor;
automatically ceasing, response to the temperature sensed by the temperature sensor rising above a threshold temperature, the delivery of light from the light source to the target tissue; and
automatically delivering, in response to the temperature sensed by the temperature sensor rising above the threshold temperature, electrical stimulation to the target tissue via at least one electrical stimulation electrode while the delivery of light to the target tissue is ceased.

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.
