Abstract:
Methods of fabricating a polymeric implantable device with improved fracture toughness through annealing are disclosed herein. A polymeric construct is annealed with no or substantially no crystal growth to increase nucleation density. After the annealing, crystallites are grown around the formed nuclei. An implantable medical device, such as a stent, can be fabricated from the polymer construct after the crystallite growth.
