Research reveals innovative 4D-printed vascular stents improve deployment efficiency for minimally invasive therapy.
4D-Printed Vascular Stents In their Research Article (10.1002/adfm.202521468), Kayo Hirose, Shinjiro Umezu, and coworkers fabricate a micro-stereolithography 4D-printed stent via ultraviolet photocrosslinking of a polycaprolactone (PCL)-based material system. Diethyl phthalate (DEP) is incorporated to regulate the shape memory threshold of the manufactured structure, enabling intelligent deployment at physiological temperature with advanced thermoresponsive performance, mechanical compliance, and biocompatibility for personalized minimally invasive vascular therapy.
