Cold hibernated elastic memory CHEM

Sokolowski, W, 2005. Potential bio-medical and commercial applications of cold hibernated elastic memory (CHEM) self-deployable foam structures. Smart Materials HI 5648, 397 05. 

Metcalfe et al. (2003) tested cold hibernated elastic memory (CHEM) polyurethane for the treatment of lateral wall aneurysms on the carotid arteries of dogs. The SMP polyurethane was made in open cellular (foamy) structures with the glass transition temperature of 60 C. After 3 weeks, in vivo experiments showed that the CHEM foam led to improved aneurysm embolization, and a thick neoin-tima formation by favoring the ingrowth of cells. However, residual necks and recurrences were observed in some cases due to the incomplete filling of the vascular lumen. 

In 2003, Metcalfe et al. reported on using polyurethane SMP foams, termed CHEM (cold hibernated elastic memory) foams, for treating carotid aneurysms in a...
