The bare metal stent (BMS) used in the blood vessel caused the restenosis after the operation due to formation and proliferation of neointimal. Recently, as a method to overcome the problems of BMS, drug eluting stent (DES) is developed and being applied to human body which has drug reducing restenosis applied on the metal surface. DES has the advantage of greatly reducing the restenosis after the operation; however, metal stent remains in the body after the drug is released causing issues such as late thrombosis and restenosis so that currently the attention is increasing for biodegradable materials that reduce restenosis and thrombosis by degrading as a certain amount of time passes after the drug is released by the stent material. In this review, the study trend of biodegradable stent will be explained.
