Abstract
A method and device are provided for directing laser radiation to a body cavity site. A hollow, elongate, optical fiber is advanced 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 a transverse, substantially flat, annular, energy delivery surface for emitting laser radiation transmitted by the fiber generally parallel to the axis. The radiation is intercepted axially adjacent the energy delivery surface and is reflected in a beam radiating substantially transversely of, and substantially around, the axis. A reflector block is provided for reflecting the radiation and is connected to an actuator for locating the reflector block at selected axial positions along the axis whereby the beam irradiates the body site along the axis.
