摘要:
Described herein is an intravascular flow modifier that comprises a plurality of annular support members and a plurality of cross-struts. The plurality of annular support members are interwoven with the plurality of cross-struts to form a tubular framework. The annular support members and cross-struts are formed of a shape memory polymer which has shape memory properties and a glass transition temperature that is above body temperature. The tubular framework has a compressed configuration at a temperature below body temperature and an expanded configuration at a temperature above body temperature. In the expanded configuration the tubular framework has an enlarged inner and outer diameter when it is heated above the glass transition temperature.
