Abstract

Bioabsorbable stent is new technology that has been developed to solve problems and reduce the limitations of existing stents. The scaffold made of Bioabsorbable biomaterial after releasing the drug and coronary artery scaffolding, is degradation and disappear in the body at a certain time. These stents have opened a new horizon in interventional cardiology and have long term benefits such as positive remodeling, reducing the incidence of late and very late scaffold thrombosis, no need long term anti-platelet therapy, reducing restenosis and do not create obstacles for future treatment. The development of this technology is progressing rapidly due to its importance, so that many research centers and medical engineering companies in the world are currently researching on these stents. The purpose of this paper is to review the development process and introduce approved or developing biodegradable coronary scaffolds.
