Abstract: A method for manufacturing a bioabsorbable stent and an apparatus for doing the same are disclosed. The method includes providing a polymer resin, melting the polymer resin to form a molten hollow parison, cooling the molten hollow parison to form a hot hollow parison, elongating the hot hollow parison, expanding the hot hollow parison by feeding a compressed gas into the hot hollow parison to form a stent preform, and patterning the stent preform to form a bioabsorbable stent.

Abstract: Branched polycarbonates are prepared by the reaction of a linear or branched polycarbonate with a branching resin having a molecular weight up to about 3,000, typically a novolak or a bisphenol polymer. The reaction preferably takes place in the presence of a carbonate equilibration catalyst such as a quaternary bisphenolate.

Abstract: The efficiency of a redistribution catalyst during polycarbonate redistribution is improved by employing an extruder screw design that provides a melt seal between the extruder throat and the vacuum port. A melt seal exists when the free volume within the extruder is sufficiently filled with molten resin so as to prevent the passage of gases between sections of the extruder.
