An illumination sleeve includes an elongated, hollow, flexible cylindrical body with the body formed of a resin and having an optical source end, an illumination end, and a central axis. An annular wall extends around the central axis and includes a plurality of optical cores therein. Each optical core is formed of a resin and includes a core axis generally parallel to the central axis. The annular wall further includes a plurality of cladding portions, with each cladding portion being formed of a resin. The plurality of optical cores have a core index of refraction and the plurality of cladding portions have a cladding index of refraction. The cladding index of refraction is less than the core index of refraction and each optical core is surrounded by and in contact with one of the cladding portions to form an optical waveguide. |
