Abstract
Perfusion dilatation catheter and method of manufacturing the same. The catheter has an elongated flexible shaft with an inflatable balloon mounted near the distal end of the shaft. A first lumen in the shaft communicates with the balloon for inflating and deflating the balloon. A second lumen extends between the proximal and distal ends of the shaft and is adapted to receive a guide wire. Openings formed in the side wall of the shaft on the proximal and distal sides of the balloon communicate with the second lumen to provide a path for blood to flow past the balloon when it is inflated.
