Abstract
A device for incising and dilating a stenosis in a vessel of a patient includes a catheter having an inflatable balloon near its distal end. A laser rod formed with a light groove on its distal portion is bonded to the catheter with the light groove positioned on the balloon. In the operation of the device, the catheter and laser rod are inserted through the vessel to place the balloon and light groove in contact with the stenosis. Laser light is then directed through the laser rod for emission from the light groove to incise the stenosis. Simultaneously, the balloon is inflated. This inflation of the balloon causes further incision of the stenosis and dilatation of the stenosis.
