Over the last few years, we have developed shape memory polymers (SMPs) with several properties suitable for use in minimally-invasive biomedical devices. These properties include biocompatibility, the ability to fully recover large strains, the potential to serve as medication reservoirs for drug delivery, and low production cost. We and others have proposed use of shape memory polymers for various applications including cardiovascular stents, an endovascular clot removal system, and a self-tying suture.
