Abstract
Methods and systems have been developed allowing for increased strain storage in shape memory polymer devices. Larger stored strains allow for smaller and different implantable shapes of shape memory polymer devices. For example, by storing a larger strain, a shape memory polymer device may be implanted at a smaller fraction of its final implanted shape. Benefits include shorter patient recovery times, smaller implantation sites, and flexibility of implantation techniques.
