ABSTRACT:
Disclosed is a therapeutic device including an optical source including means for generating ultraviolet (UV) radiation, and a light delivery apparatus. The light delivery apparatus includes a body member and a plurality of optical fibers extending therefrom. Each of the optical fibers includes a proximal tip affixed to the body member, a distal tip at the end of the fiber opposite the proximal tip, and means for coupling the generated radiation from the proximal tips of the fibers through the fibers, and to the distal tips. The distal tips are characterized by a radius of curvature in the range 0.25 to 2.0 mm. The coupling means includes a flexible central core disposed within a flexible outer cladding. The central core has a diameter in the range of 0.1 mm to 1.0 mm, and the cladding has a refraction less than the index of refraction of the core.
