Biomaterials: Self-Adjusting, Polymeric Multilayered Roll that can Keep the Shapes of the Blood Vessel Scaffolds during Biodegradation (Adv. Mater. 28/2017)

A self-adjusting, blood vessel-mimicking, multilayered tubular structure with two polymers, which can keep the shape of the scaffold during biodegradation, is described in article number 1700171 by Wei Bai, Wenfu Zheng, Xingyu Jiang, and co-workers. The inner layer of the tube can expand whereas the outer layers shrink to maintain the stability of the shape and the inner space of the tubular shape. This approach is useful for making scaffolds that require the maintenance of a defined shape, based on FDA-approved materials.
