Abstract:
Methods for fabricating a polymeric stent with improved fracture toughness including radial expansion of a polymer tube and fabricating a stent from the expanded tube are disclosed. The polymer tube is disposed within a mold and may be heated with radiation. The heated tube radially expands within the mold.
