Implantable device formed from polymer blends
First Claim
1. An implantable medical device comprising a frame structure, the frame structure being formed from at least two polymers, one of the at least two polymers having a substantially higher ultimate strain than the other of the at least two polymers, and a radiopaque material blended to create a deformable frame structure having increased toughness.

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. The polymeric materials may include additives such as drugs or other bioactive agents as well as radiopaque agents. By preferential mechanical deformation of the polymer, the polymer chains may be oriented to achieve certain desirable performance characteristics.
