  • Patent number: 11285293
    Abstract: A device disclosed herein includes a tubular member which is flexible and configured to receive ultraviolet (UV) light from a UV illumination coupler. The tubular member contains a lumen defining a longitudinal interior space within the tubular member, a tubular body bounded by an inner wall defining an outer boundary of the lumen and an outer wall defining an outer surface of the tubular member, at least one optical fiber disposed outside of the interior space not parallel to an axis of the lumen and adapted to receive the UV light from the UV illumination coupler, and a protective component adapted to prevent substantively all of the UV light emitted from the optical fiber from exiting the outer wall. Methods for producing and using such devices are also disclosed herein.
