Abstract
An optical energy transmission device and a related method includes a flexible fiber optic rod and a flexible sheath surrounding and spaced from the fiber optic rod, with a disc member fixed in edge contact with both the rod and the sheath for supporting and uniformly spacing the rod from the sheath. The inner and outer periphery of the disc is arched in order to permit cooling fluids to pass relatively unimpeded along the passageway along the rod and the outer sheath, while maintaining the desired position of the rod relative to the sheath.
