A method and device are provided for directing laser radiation to a body cavity site. A hollow, elongate, optical fiber is advanced, usually in a containing device, to the vicinity of the site and coupled to a laser source with a distal end region of the fiber extending along a longitudinal axis. The fiber terminates in an energy delivery surface for emitting laser radiation transmitted by the fiber. The radiation is intercepted at a location axially aligned with the energy delivery surface and is reflected in a beam radiating substantially transversely of, and substantially circumferentially around, the axis. A reflector member or block is provided for reflecting the radiation and is mounted in an open end of the catheter at a selected axial position along the axis. A fluid, such as a flushing fluid, can be directed between the end of the fiber, against the reflector member, and to the body site.

A coupling system for coupling a beam of radiant energy from a laser to a fiber optic cable includes a secondary transmission path which surrounds the input end of the fiber optic cable and provides an optical path for energy which is not transmitted by the fiber optic core but is lost. Displaced from an output end of the secondary transmission path is a multi-faceted reflector. The reflector is displaced sufficiently from the output end of the secondary transmission path so that the power density of the radiation incident thereon is reduced sufficiently so as to not damage the facets thereof. The coupling system is contained within a heat sink which receives the reflected and lost radiant energy harmlessly converting same to heat.

A dispensing package for a fiber-optic cable comprised of two mating members and a separator disposed therebetween. The two mating members have centrally located openings and are joined at their mating edges and define a cavity therebetween. The separator is secured between the mating members to divide the cavity into first and second cable receiving chamber. Each cable receiving chamber accommodates a circularly coiled cable portion. A fiber-optic cable passes through the separator and opposite cable ends exit respectively from the central apertures of each mating member to allow cable to be payed out from opposite sides of the package. A series of apertures in the mating members and separator define a plurality of flow passages through the package for sterilization purposes.
