Abstract
A dilation catheter suitable for use in medical procedures is provided. The catheter includes a balloon disposed on an elongated tube. The tube is capable of passing fluid between the balloon and the tube for varying the balloon between an inflated expanded condition and a deflated collapsed condition. The balloon includes a longitudinally extending spiral wall which forms a longitudinally extending spiral channel spaced inwardly from the exterior surface of the balloon when the balloon is in its expanded condition to allow fluid to be perfused past the balloon.
