1. A fiber optic transmission and diffusion apparatus comprising:

  • a plurality of optical fibers having proximal and distal ends, the proximal ends adapted for coupling to a source of phototherapeutic radiation;

    wherein each optical fiber has connected to its distal end a tip assembly for directing radiation outward, each tip assembly being arranged in a loop configuration to form a loop diffuser; and

    a housing surrounding the optical fibers and each of said loop diffusers, wherein each of said loop diffusers are expandable out of and retractable back into said housing.
