摘要：A blow molding apparatus for expanding a polymer tube and a method forfabricating a stent using the apparatus is disclosed. The polymer tube is disposed within a
tubular mold, over which a heated ring is made of a material having thermal conductivitygreater than the tubular mold is translated. The ring is heated with heated fluid streamsapplied directly onto an outer surface of the ring, or heated fluid circulated within thering, or an electrically resistive coil within the ring, or combinations thereof. The heatedring uniformly heats a circumference of the tubular mold that, in turn, uniformly heats acircumferential band of the polymer tube. The heated polymer tube is progressivelyexpanded radially and axially while the ring is translated longitudinally over the polymertube. The expanded polymer tube can be heat set and cooled prior to removal from thetubular mold.
