Shape-memory materials have been proposed in biomedical implantation devices due to their ability to facilitate minimally invasive surgery, particularly in cardiovascular stent interventions. Therefore, our laboratory has been developing a completely degradable bi-layer polymeric stent with self expandability, which not only plays a dual role of maintaining or increasing the lumen of a vessel without causing excessive injury as well as providing the capability to deliver one or more drugs concurrently to the target site, but will disappear completely after healing.
