Abstract
A method of manufacturing a medical instrument for diffusing light from an optical fiber is provided. The medical instrument includes an optical fiber having a proximal portion including a cladding layer surrounding the core and a distal portion having a diffuser tip comprising a protective coating made of acrylic or methylpentene surrounding the core, an optical coupling layer, and a sleeve. The protective coating strengthens the distal end of the optical fiber so that it can withstand a higher bending moment at failure than the uncladded core. At the same time, the protective layer has an index of refraction that is between the indices of refraction of the core and the optical coupling layer to direct light out of the core through to the optical coupling layer.
