    摘要： Methods are disclosed for improving the storage performance of polymeric stents that reduce or eliminate the effects of long term aging on the properties of the stents. A polymeric stent or a polymeric tube from which a stent is made is heated to a temperature between ambient and the glass transition temperature of the polymer for a period of time. The heating causes densification or an increase in density of the polymer which stabilizes the properties of the polymer in later processing steps and storage. The stent can be made from a polymeric tube that is expanded at a temperature above the glass transition temperature and cooled to maintain an expanded diameter.

    摘要： Disclosed is a method for fabricating a stent, the method comprising: positioning a polymeric tube inside a mold, wherein a high thermally conductive element covers at least a portion of the outer surface of the mold, the high thermally conductive element having a thermal conductivity that is greater than that of the mold; heating at least a portion of the mold; radially expanding the tube against the mold; and fabricating a stent from the radially expanded tube.
