Patent number: 5397305Abstract: A fixed-wire dilatation catheter for angioplasty procedures which has an inflated balloon on the distal end with little or no tendency to wrap on itself when the catheter is advanced through a patient's vascular system. The catheter comprises an elongated torquable shaft which is longitudinally relatively flexible but diametrically relatively rigid, a guide extension secured to the distal end of the elongated torquable shaft, and a balloon assembly which is mounted about the distal section of the torquable shaft and the guide member so that the balloon assembly is free to rotate about the torquable shaft and guide member and thereby avoid balloon wrapping. An elongated flexible member such as a helical coil is secured to the portion of the guide member which extends distally of the balloon.Type: GrantFiled: November 30, 1992Date of Patent: March 14, 1995Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Paul J. Kawula, Ray R. Beitelia, Erik J. vander Burg, Michael S. Williams
