Patent ID: 8206426

Claim:
A phototherapy apparatus comprising: a handpiece comprising a body member and a grip; a plurality of elongated light transmitting elements, wherein the light transmitting elements each comprise an optical fiber, each of said elements extending between a proximal end enclosed within the body member and a distal end located outside of and distal to the body member; an ultraviolet light source; a light collection element; and one or more optical coupling elements; wherein the proximal ends of the light transmitting elements are located in close proximity to each other and comprise a fiber bundle, said bundle having an entrance face comprised of the tips of the proximal ends, and wherein the fibers of the fiber bundle are fused in proximity to the entrance face, wherein the light collection element is configured to collect at least a portion of the light emitted from the light source, wherein the one or more optical coupling elements are configured to direct at least a portion of the collected light to the entrance face comprised of the tips of the proximal ends of the light transmitting elements to couple at least portion of the collected light into the light transmitting elements, wherein light coupled into each of the light transmitting elements is transmitted along the element and emitted from the distal end.
