TEMPERATURE-DEPENDENT SHAPE MEMORY POLYMER

WIPO Patent Application WO/2021/261915

A1

The present invention relates to a shape memory polymer that can be restored to an original shape from a deformed shape by means of body temperature in the body. When using the shape memory polymer of the present invention and a device for wrapping the outer wall of blood vessels prepared thereby, it is possible to effectively prevent abnormal blood vessel dilatation, and prevent stenosis by effectively inhibiting neointimal formation.
