Fiber optic psoriasis treatment device

A kit for the treatment of psoriasis comprising:

• A. a therapeutic device including:
• an optical source including means for generating ultraviolet (UV) radiation;
• and
• a light delivery apparatus including a body member and a plurality of optical fibers extending therefrom, each of said fibers including:
• a proximal tip affixed to said body member;
• a distal tip at the end of said fiber opposite said proximal tip, wherein the butt end of substantially all of said distal tips are characterized by a radius of curvature in the range of 0.25 to 2.0 mm;
• means for coupling said generated radiation from said proximal tips of said optical fibers through said fibers, and to said distal tips, said coupling means including a flexible central core disposed within a flexible outer cladding, said central core having a diameter in the range of 0.1 mm to 1.0 mm, and said cladding having a refraction less than the index of refraction of said core, and
• B. a lubricant having an index of refraction intermediate of the index of refraction of said core and a predetermined reference value wherein said lubricant has an index of refraction intermediate of the index of refraction of said core and a reference value of about 1.55.
