ABSTRACT:
An elastomeric balloon is secured to one end of a catheter and stretched in order to reduce the balloon cross-section and facilitate its placement within an occluded section of a blood vessel. Stretching of the balloon is achieved by attaching the mouth of the balloon to the distal end of the catheter and extending the body of the balloon with a piston carried by the catheter for extension relative thereto. Once in place, the balloon is expanded through the injection of a volume of fluid into the catheter, thereby pressing the occlusion against the wall of the blood vessel to increase the patency of the vessel.
