Resorbable complex shape memory poly(propylene fumarate) star scaffolds for 4D printing applications

Abstract

In various embodiments, the present invention is directed resorbable star PPF 4D printed structures with compressive shape memory properties. In some embodiments, these printed structures may be compressed at room temperature from a first thickness to a second thickness for insertion into the body, where they reach body temperature and expand into a desired (third) thickness. The compression and expansion of these resorbable star PPF 4D printed structures allows for easier insertion of things such as, bone scaffold and stents (e.g., vascular stents, kidney stents, urethral stents, colitis stents, esophageal stents, colon stents, intestinal stents, or venous stents) into the body, as they can be compressed prior to insertion.
