LIGHT DELIVERY DEVICE THAT PROVIDES A RADIAL LIGHT OUTPUT PATTERN

摘要

A light delivery device (100) comprising an optical fiber (10) having a non- feature portion (16) and a feature portion (18) having features (20) that force light to couple out radially from the feature portion (18) and provide a desired radial light output pattern. A method of photodisinfection of a cavity comprising of providing this device (100), apply a photosensitizing composition (48) to treatment site within the cavity, and inserting at least a portion of the device (100) into the cavity; and applying light delivered by the device (100) from a light source to the treatment site within the cavity at a wavelength absorbed by the photosensitizing composition so as to inhibit or eliminate microbes located at the treatment site. The present invention also includes a method of making the device and a treatment kit containing the device (100) and a container (50) containing a photosensitizing composition (48).
