Abstract
In general, in one aspect, the disclosure features a system that includes a flexible waveguide having a hollow core extending along a waveguide axis and a region surrounding the core, the region being configured to guide radiation from the CO2 laser along the waveguide axis from an input end to an output end of the waveguide. The system also includes a handpiece attached to the waveguide, wherein the handpiece allows an operator to control the orientation of the output end to direct the radiation to a target location of a patient and the handpiece includes a tip extending past the output end that provides a minimum standoff distance between the output end and the target location.

26. A system, comprising:
-
a waveguide including a hollow core extending along a waveguide axis, the waveguide being configured so that during operation the waveguide guides radiation along the waveguide axis from an input end to an output end of the waveguide and delivers the radiation to a target location; a fluid source configured so that during operation of the system the fluid source delivers fluid to the hollow core of the waveguide via the input end of the waveguide; a cap positioned at the end of the waveguide and configured to block fluid exiting the output end of the waveguide from the target location; and a tube extending along the waveguide axis, the tube being configured so that during operation of the system the tube channels fluid exiting the output end of the waveguide away from the output end and away from the target location, wherein the cap comprises an exhaust port that during operation of the system provides a pathway for the fluid exiting the core to flow into the tube. - View Dependent Claims (27, 29, 31, 32, 34, 35, 36, 37)
