Abstract
A method of manufacturing a folding balloon catheter for use as an angioplasty device, wherein the balloon catheter has atherotomes attached to the exterior of the balloon, includes inflating a balloon to its expanded state. A plurality of patches of a curable elastomer adhesive are then applied at selected locations on the outside surface of the inflated balloon, and an atherotome is attached to the balloon at each of the patches. The inflated balloon, with attached atherotomes, is then partially cured to more firmly attach the atherotomes to the balloon. The balloon is then deflated to a contracted configuration in a manner which forms a plurality of flaps in the balloon between the atherotomes. The deflated balloon is then cured to completion to establish a permanent set in the flaps which enable the balloon catheter to be repeatedly inflated and deflated during operation between predictable expanded and contracted configurations.
