Abstract
A catheter for vascular surgery includes a circular array of lightguides disposed at the distal end of the catheter about an inflatable balloon. Upon pressurizing the balloon the diameter of the catheter expands. The lightguides 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.
