| 摘 要： | 钛合金血管内支架由钛合金管经激光雕刻而成，此类支架血管壁之间是面接触，能够提供较高的径向支撑强度．对新型钛合金血管内支架的加工、表面处理、性能测试、生物学评价等4个方面做了系统研究．激光雕刻后的钛合金血管支架通过机械、电化学等方法进行表面处理后，经测试，得出：钛合金血管内支架柔韧性好、支撑力强，回缩率低，整体性能达标，且具有优良的生物相容性，再狭窄率低，符合现有国际支架的标准。

| Abstract: | Most new titanium alloys stents are cutting by laser in tubular structure, it is surface-contact with vascular wall, This structure can provide a higher intensity in radial support, and compared with other types of structures the dominance is that the tubular structure stent wall thickness is more thin in same intensity. On another hands, the thin thickness is good for blood flowing. Through the titanium alloy stent research on machining, surface treating, performance and biological appraisal. It has been known that titanium alloy stent have more better performance, lack on renarrow and without toxicity, it is safe on human ues. |
