  • Publication number: 20140084515
    Abstract: Methods of fabricating a polymeric implantable device with improved fracture toughness through annealing, nucleating agents, or both are disclosed herein. A polymeric construct that is completely amorphous or that has a very low crystallinity is annealed with no or substantially no crystal growth to increase nucleation density. Alternatively, the polymer construct includes nucleating agent. The crystallinity of the polymer construct is increased with a high nucleation density through an increase in temperature, deformation, or both. An implantable medical device, such as a stent, can be fabricated from the polymer construct after the increase in crystallinity.

  • Patent number: 8679396
    Abstract: A stent having a stent body made from a crosslinked bioabsorbable polymer is disclosed. A method of making the stent including exposing a tube formed from a bioabsorbable polymer to radiation to crosslink the bioabsorbable polymer and forming a stent body from the exposed tube is disclosed. The tube can include a crosslinking agent which induces crosslinking upon radiation exposure. Additionally or alternatively, the bioabsorbable polymer can be a copolymer that crosslinks upon exposure to radiation in the absence of a crosslinking agent.
