In situ formation of micro/nano phase composite for 3D printing clinically relevant bioresorbable stents.

ABSTRACT: With recent developments in materials engineering and additive manufacturing, the feasibility of patient-specific biomedical devices has increased substantially. Bioresorbable vascular stents/scaffolds (BVS), implants which reopen narrowed blood vessels, have seen considerable research in freeform fabrication as one such potentially customizable medical device. However, clinical requirements for stents place significant limits on manufacturing; the device must maintain the vessel's natural diameter once it has been reopened and must have sub-100 μm radial thickness to allow proper blood flow in small diameter vessels. Recent commercialization challenges for BVSs have highlighted the importance of meeting these requirements. For example, the first BVS marketed in the U.S.A., made from polyl
