ABSTRACT:
A method is provided for manufacturing a balloon for a catheter. The method comprises the steps of providing a mold having a mold cavity that generally corresponds to an intended expanded form of the balloon. Securing elements are provided at opposite ends of the mold cavity for securing end sections of a tubular parison. The end sections of the tubular parison are twisted in opposite directions with respect to each other. The end sections of the tubular parison are secured in the securing elements, the parison is heated, and a pressure differential is created between the inside and the outside of the parison to cause it to expand into a balloon against the walls of the mold cavity. The previously twisted end sections of the parison result in the balloon transition sections having spiral ridges, allowing the balloon to be folded into a small diameter.
