The demand for implantable medical devices and biodegradable polymers for clinical use had been increasing along with the continuous growth of population. Biodegradable, photocurable polymeric material coupling with additive manufacturing provides a fast and customizable option to make biocompatible, biodegradable devices. Therefore, based on the synthesis of poly(glycerol sebacate)-based photocurable biodegradable polymer, poly(glycerol sebacate) acrylate (PGSA), vinyl acetate (VAc) is added to increase the mechanical properties while maintaining the biodegradability. With UV-curing, the mechanical property can be more stable and most importantly is that the shape of polymer can be controlled by additive manufacturing. With the material, inferior vena cava (IVC) filter is developed for Venous thromboembolism (VTE) patients, the IVC filters can not only catch the clots but also function as a stent to keep the vein open. In my work, with different types of design of IVC filter, the capturing ability by capturing the PS beads can be observed in flow pipes to simulate the blood flow in human body.
