    摘要： An endovascular laser treatment device for causing closure of a blood vessel uses an optical fiber adapted to be inserted into a blood vessel. An inner sleeve is arranged around a distal portion of the optical fiber core such that both distal ends of the inner sleeve and the optical fiber core form an enlarged light emitting face. The enlarged emitting face provides substantially lower power density while providing the same amount of total energy during a treatment session. An outer sleeve arranged around the inner sleeve acts as a spacer to position the light emitting face away from an inner wall of the blood vessel. The enlarged light emitting face and the outer sleeve acting as a spacer reduces the possibility of thermal run-away and device damage, and reduce the possibility of vessel perforations, leading to less bruising, post-operative pain and other clinical complications. In yet another aspect of the present invention, a spacer comprises an inner sleeve and an outer sleeve both arranged around a distal portion of the core to prevent the laser light from traveling laterally and to position the light emitting face away from an inner wall of the vessel. The inner sleeve can be a heat resistive material such as ceramic and the outer sleeve can be, for example, a metallic sleeve to provide structural integrity and strength to the distal section of the treatment device.

    摘要： A temperature of a laser treatment area is monitored and an output of a laser is controlled or modulated to prevent damage resulting from thermal runaway or burn back. The detector may be positioned proximate or at a distal end of the fiber, and may be in the form of a detector arranged to detect leakage of higher order propagation modes from a bend in the fiber. Manual or automatic cleaning of the fiber may be initiated upon detection of overheating, either by dipping the fiber in a cleaning solution or supplying cleaning fluid to the fiber or treatment area. A fiber position detector may also be included to prevent damage when the fiber is withdrawn into an introducer or catheter. UV radiation may be applied to the treatment site to prevent closing down of blood vessels upon introduction of a catheter or the bare fiber.

    摘要： A transparent ferrule is fused to an end of an optical fiber to increase the coupling area without altering the input numerical aperture of the fiber system. This is accomplished by controlling the length of the area at which the transparent ferrule is fused or welded. In addition, an extended ferrule portion is situated behind the fusion area and is separated from the fiber core such that light that fails to couple to the core is reflected from the inner diameter of the extended ferrule portion away from the fiber core, where it can be deflected or dissipated by a beam block or absorptive material. The transparent ferrule is formed from a plurality of relative thin wall ferrules that are successively fused from the side to form at the least the termination or coupling end of the transparent ferrule.

    摘要： A fiber optic connector for coupling focused radiant energy from a laser to a fiber optic conductor includes a secondary transmission path and one or more reflectors and/or heat sinks for deflecting errant radiant energy to a location where it be safely dissipated. In addition, coupling of the radiant energy to the cladding of the fiber is minimized by stripping or at least partially removing the cladding to reduce the amount of cladding in the area that extends to the focal plane of the radiant energy source.

    摘要： A fiber optic connector for coupling focused radiant energy from a laser to a fiber optic conductor includes a secondary transmission path, one or more diffusers and, optionally, one or more internal heat sinks for diffusing radiant energy so as to and thereby minimize damage to the connector. In addition, coupling of the radiant energy to the cladding of the fiber is minimized by stripping or at least partially removing the cladding to reduce the amount of cladding in the area that extends to the focal plane of the radiant energy source, while reduction of higher order propagation modes may optionally be achieved by tapering a section of the fiber in such a manner that light entering the fiber at large critical angles are effectively collimated, i.e., bent towards the axis of the fiber.
