Abstract: Surgical instruments, end effectors for surgical instruments, and methods of using surgical instruments. An example end effector assembly includes a first jaw member and a second jaw member. The first jaw member includes: a transparent tissue contacting surface; at least one transparent viewing portion; a fluid-tight cavity configured to receive an optical fiber; and a reflector configured to reflect a substantial portion of light from the optical fiber towards the transparent tissue contacting surface. The second jaw member is configured to move towards the transparent tissue contacting surface of the first jaw member.

Abstract: A system for use in TFL lithotripsy procedures uses a silica trunk fiber semi-permanently mounted in an endoscope and includes a detachable and replaceable wave guide treatment tip, including hollow wave guides and fiber tips. The system provides for ready removal and replacement of wave guides damaged during lithotripsy. The trunk fiber in the endoscope tube is of diameter ?200 ?m, suitable for use in the lower pole of the kidney, and should be useful over-and-over with only the detachable wave guide removed and replaced, whether during a single procedure or for multiple procedures on different patients in which the endoscope tube and trunk fiber are sterilized between patients. Multiple connector assemblies are provided for optical coupling contact between the detachable wave guide and trunk fiber and include a gap for dissipation of heat between the trunk fiber and the wave guide when in optically coupling contact.

Abstract: 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.
