Shape Memory Polymer (SMP) Foams

SMP foams are low density polyurethane. SMP foam formulation and pore sizes can be modified to create materials with a wide range of different properties.

After a SMP foam is created in its primary expanded shape, it is then crimped into a convenient secondary shape (e.g. for catheter delivery). Only when the SMP foam further experiences pre-specified conditions will it recover its primary expanded shape (e.g. in a blood vessel).

Preclinical work has shown SMP foams to have many properties attractive for use in vascular embolization devices.
