Abstract

A biocompatible material may be configured into any number of implantable medical devices including intraluminal stents. Polymeric materials may be utilized to fabricate any of these devices, including stents. The stents may be balloon expandable or self-expanding. By preferential mechanical deformation of the polymer, the polymer chains may be oriented to achieve certain desirable performance characteristics.
