Abstract
An apparatus for directing laser energy to a vascular occlusion comprises a catheter and a plurality of optical fibers disposed in an annular array about a central axis at the outer wall of the catheter. The distal end of each fiber is beveled at an angle and is oriented away from the central axis and perpendicular to a plane formed by the central axis and the center of the distal end of the respective fiber, whereby the output of the fibers are directed toward the central axis and converge at a common focal point.
