    摘要: A stent includes a marker that has a biodegradable body and a plurality of radiopaque nanoparticles dispersed in the body. The marker is disposed in a hole on a biodegradable structural element of the stent, and the marker and the hole have substantially the same configuration. A method for making a stent includes mixing radiopaque nanoparticles with a biodegradable material to form a stent marker, forming a hole on a structural element of a biodegradable stent for accommodating the stent marker, wherein the stent marker and hole have substantially the same configuration, and disposing the stent marker in the hole.
