摘要:
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. The stent has a plurality of hoop components interconnected by at least one flexible connector. The hoop components are formed as a continuous series of alternating substantially longitudinally oriented strut members and connector junction struts, whereas the longitudinal strut is connected to the connector junction strut by alternating substantially circumferentially oriented arc members.
