Abstract

A low-profile, diffusive tip apparatus adapted for insertion into a body to deliver phototherapeutic radiation by scattering light in a substantially omnidirectional pattern includes a light-transmissive housing that is adapted for mounting, at its proximal end, onto a fiber optic cable, and, at its distal end, the housing defines or is joined to a light-transmissive cap having a diameter which is not substantially greater than the diameter of the optical fiber. The light transmissive cap region encloses a chamber or reservoir filled with an optically scattering medium and, preferably, hemispherical in shape with a radius of curvature substantially equal to the radius of the housing.
