ABSTRACT:
The invention relates to a balloon for a catheter. The manufacturing of the balloon comprises providing of mold which has a mold cavity corresponding to an intended expanded form of the balloon member; placing opposite ends of a tube-like semimanufacture (parison) into securing elements for the purpose of securing their opposite end sections in the mold cavity; heating the semimanufacture; and generating a pressure difference between the inside and the outside of the semimanufacture to expand the balloon member against the walls of the mold cavity. In the molding, the end sections of the semimanufacture are twisted about an angle in relation to each other so that helical ridges are formed in balloon transition sections.
