摘要：
Provided is a biodegradable polymer coating stent effective in delaying the damage of physical properties (particularly radial force) of a core structure. The stent includes a core structure of a bioabsorbable material (e.g., Mg), a first coating layer of a first polymer with biodegradability, and a second coating layer of a second polymer with biodegradability, wherein the first coating layer covers the whole surface of the core structure； the second coating layer covers a part or the whole surface of the first coating layer； the first polymer has a glass transition point of lower than 37°C； and the second polymer has a glass transition point of 47°C or higher.
