摘要

A stent has mechanical properties changing in a multistage manner and capable of effectively exhibiting functions thereof in response to a period after indwelling. A stent includes linear struts forming an outer circumference of a cylindrical shape with gaps formed therein and a plurality of link sections each containing a biodegradable material and connecting the struts to each other in each of the gaps, includes at least two link sections having different decomposition periods under identical conditions.
