Abstract: A device for conveying high energy electromagnetic radiation from a laser source to an optical fiber which comprises a sleeve (1) having a proximal end and a distal end and being adapted to enclose a liquid (4) which is transparent to said radiation, the distal end of said sleeve being adapted to be attached to the input end of the optical fiber (3); and a focussing lens (2) attached to the proximal end of said sleeve said liquid having a refractive index which substantially matches the refractive index of the lens and of the optical fiber. A process for removing an obstruction by laser surgery using said device is also disclosed.

Abstract: A novel use of an apparatus comprising a laser (1) capable of generating electromagnetic energy and one or more optical fibers (2) connected to the laser at one end and adapted to emit electromagnetic energy at the other end is disclosed. This novel use is in a method for reducing an arteriosclerotic lesion In which electromagnetic energy directed at the lesion is selectively absorbed by a lesion component, e.g. cholesterol. The resulting decomposition of said lesion component leads to reduction of the lesion which minimal risk of damage to blood constituents and adjacent healthy blood vessel tissue. Preferably, monochromatic electromagnetic energy is generated by the laser (1) and is conducted to the vicinity of the lesion by the at least one optical fiber.
