Mechanical requirements of shape-memory polymers in biomedical devices

Shape-Memory polymers are emerging from the academic laboratory into the clinical field, providing new functionality to often static biomedical implants. The purpose of this review is to discuss why their mechanical properties, particularly toughness, must be considered in order for them to reach a broader clinical use. The limitations of current Shape-Memory polymers, from a mechanical perspective will be provided, with an emphasis on the effects of the in vivo environment on both mechanical- and Shape-Memory properties. Finally, the most recent advancements in improving Shape-Memory polymers for biomedical use will be highlighted. © 2013 Copyright Taylor and Francis Group, LLC.
