摘要：

A bioabsorbable scaffold composed of a multilayer structure of alternating layers of different polymers is disclosed. The multilayer structure can have 20 to 1000 layers and the individual thickness of the layers can be 0.2 to 5 microns. A method of making the scaffold including a layer multiplying extrusion process is disclosed.
