1. A method for fabricating a stent, the method comprising:
- positioning a polymeric tube inside a tubular 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;
allowing the tube to radially expand within the mold; and
fabricating a stent from the radially expanded tube.
