BIODEGRADABLE STENT AND SHAPE MEMORY EXPANDING METHOD THEREFOR

摘要

The present application relates to a biodegradable stent and a shape memory expanding method therefor. According to one embodiment of the present application, the radial force of a biodegradable stent can be greatly increased through a shape memory expanding method of the biodegradable stent, and the number of cracks can be reduced after crimping and stent deployment.
