Abstract:
1. A light diffusing device, comprising: an optical fiber defining a longitudinal dimension, a lateral dimension, a proximal end, a distal end wherein: a) the optical fiber includes b) the optical fiber includes a light emitting section and at least one non-light emitting section; c) the light emitting section is located outside the distal end of the optical fiber and includes a proximate end and a distal end; d) the light emitting section is defined by at least one removed core fiber section; e) a portion of the cladding and a portion of the core fiber located beneath the portion of the cladding are removed to form each of the at least one removed core fiber section and the removal of the portion of the core fiber increases surface area of the core fiber; f) the at least one removed core fiber section exposes a progressively increasing amount of the surface area of the core fiber in a distal direction within the light emitting section, resulting in a desired distribution of the light emitted from the light emitting section.
