ABSTRACT:
A catheter for vascular surgery includes a circular array of optical fibers therein disposed at the distal end of the catheter with each lightguide being separated by an elastically deformable member with compartments therein for receiving pressurized fluid. Upon pressurizing the compartments the diameter of the catheter expands. The optical fibers are bunched at the end of the catheter proximate the source of laser light where shutters are positioned for selecting only those lightguides at the distal end which are needed to remove blockages. By pressurizing selected elastically expandable members, groups of optical fibers can be isolated from the rest of the optical fibers and deflected toward the wall of the vessel in which the catheter is being used.
