1. A method of manufacturing a stent, the method comprising:
disposing a polymeric tube into a cylindrical mold, the cylindrical mold comprising an inner surface facing the polymeric tube, the inner surface having an inner diameter that varies along an axial length of the cylindrical mold;
expanding the polymeric tube in radially outward directions to form an expanded tube, the expanding including blowing a gas or liquid into the cylindrical mold so that an outer surface of the polymeric tube conforms to the inner surface of the cylindrical mold and so that the outer surface of the expanded tube has an outer diameter that varies along an axial length of the expanded tube; and followed by
cutting the expanded tube to form interconnecting struts.
