View the Complete Application at the US Patent & Trademark Office
An optical nerve stimulation system for optically stimulating and locating a nerve, includes: a laser radiation source positioned adjacent to the nerve and configured to deliver laser radiation to the nerve through one or more optical fibers, thereby heating it; wherein the laser radiation source is operated in a continuous-wave mode; and a temperature sensor positioned adjacent to the nerve and a feedback loop configured to control the laser radiation source such that a predetermined temperature is maintained. The laser radiation source is one or more of an infrared laser and a near-infrared laser. Optionally, the laser radiation has a wavelength of between 1400 and 1900 nm. The one or more optical fibers are one or more single-mode fibers. The ONS probe includes one or more SMFs with chemically-etched tips and lenses for providing collimation and/or beam shaping to provide a flat-top spatial beam profile.
