For over 30 years interventional cardiovascular stenting has been developed from bare metal stents to drug- eluting stents and even today's emerging bioabsorbable stents
continuing to advance the technological therapy for the coronary heart disease. The idea of bioabsorbable stents is to leave no foreign body behind. In general
the stent functions to keep open a blocked artery and maintain the blood flow only until the vessel heals itself
so it would be ideal for the stent to disappear thereafter. Bioresorbable Polymeric Scaffold (BRPS) has gained a great deal of interest in the biomaterials field nowadays because it is made from a polymeric material which can be designed and modified for its intended use
while serving as a good drug carrier. This article discusses the roles of biomaterial
structure and processing in influencing the functions of a BRPS device
with an emphasis on the two manufacturing methods by laser cutting and 3D printing
as well as the degradation kinetics of BRPS. The challenges and trend of BRPS are also discussed.
