One step closer to using plastics to stop potentially fatal brain aneurysms

An innovative method for treating potentially fatal brain aneurysms by filling them with foam-like plastics is a step closer to clinical trials after demonstrating an ability to promote healing at unprecedented levels, says a Texas A&M University researcher who is developing the treatment.

The treatment, which makes use of special plastics called polyurethane-based shape memory polymer foams (SMPs), is the result of research by Duncan Maitland, associate professor in the university’s Department of Biomedical Engineering. Its effectiveness in helping to the heal aneurysms is detailed in the May issue of the “Journal of Biomaterials Research” and is considered a significant milestone in the continued development of the treatment, Maitland says.
