Abstract:

A device for conveying high energy electromagnetic radiation from a laser source to an optical fiber which comprises a sleeve having a proximal end and a distal end and being adapted to enclose a liquid 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; and a focussing lens 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.
