ABSTRACT:
A catheter system for intraluminal laser surgery is disclosed. The catheter system comprises an elastically expansible catheter sheath housing a plurality of optical fibers arranged in a circular array about an inflatable balloon. Inflation and deflation of the balloon expands and contracts the diameters of both the optical fiber array and the catheter. Throughout inflation and deflation of the balloon the distal ends of the fiberoptic light guides are maintained generally parallel to the lumen wall thereby maximizing the safety and efficacy of the procedure.
