摘要： 聚对二氧环己酮（PDO）编织成的可生物降解血管支架比传统金属材料支架有着生物相容性好、不易引起血管栓塞再狭窄等优点.利用动态力学实验（DMTA）方法测试PDO纤维动态力学性能，并对3种不同方法编织的支架进行动态力学测试，通过实验结果，指出了支架编织方法对力学性能的影响.

Abstract: Permanent metallic stents are associated with limitations such as continued biological interaction with the surrounding tissue, thrombosis and mismatch to the vessel size. Thus, biodegradable stents woven by polydioxanone (PDO) fiber were studied. The dynamic mechanical properties of the fiber and the stents were tested with DMTA. The results show that different weaving methods impact the mechanical properties of the stents.
