ABSTRACT:
Disclosed is a light angioplasty catheter and method for exposing the interior of a body lumen to a source of light. Light exposure may be accomplished prior to, during, or following conventional balloon dilatation. Also disclosed is a method and apparatus for exposing a preselected portion of vessel wall to a source of light. Relatively low energy light exposure has been found by the inventors herein to both inhibit restenosis following dilatation of a stenotic region, and to inhibit vascular spasms whether or not associated with a stenotic region. It may also arrest progress of a stenosis. Methods are also disclosed for cooling the vascular wall to treat a stenosis. Cooling may be accomplished prior to, during, or following dilatation.
