文题释义:
生物可降解镁及镁合金血管支架
:传统的血管支架由于长期留存于患者体内,容易导致支架内血栓等问题,可降解血管支架植入后会对狭窄的血管进行机械性支撑,同时释放出药物防止再狭窄,之后支架即缓慢降解并完全被组织吸收,血管结构以及舒缩功能完全恢复至自然状态。镁及镁合金是具备优良机械性能和生物可降解性能的材料,因此可用于制备生物可降解血管支架。

背景:专利技术的研究能够在相关领域技术发展和产业的应用中起到实际和重要的参考和启示作用。
目的:探讨生物可降解镁及镁合金血管支架专利技术现状。
方法:检索生物可降解镁及镁合金血管支架领域中国专利申请,分析生物可降解镁及镁合金血管支架专利技术的申请趋势、授权趋势、申请人地区分布、申请人类型分布、分领域专利技术和主要专利申请人的专利技术;对该领域的专利技术申请提出相关建议。
结果与结论:分析结果表明,生物可降解镁及镁合金血管支架领域国内专利申请中,国内申请人占主体地位,各分技术领域热点突出,但更多的专利技术还没有实现真正应用上的突破。

Abstract:

BACKGROUND: Research on patented technology plays a real and important role in the technological development and industrial application.
OBJECTIVE: To investigate the current patented technologies concerning biodegradable magnesium and magnesium alloy vascular stents.
METHODS: We searched the patent applications for biodegradable magnesium and magnesium alloy stents in China, and analyzed relevant information in the following aspects: application trend, authorization trend, applicant geographical distribution, distribution of applicant types, sub-sector patented technology, and patented technology of major applicants. Afterwards, recommendations for patent application in this field could be given.
RESULTS AND CONCLUSION: In China, Chinese applicants occupy a dominant position in the patent applications for biodegradable magnesium and magnesium alloy stents, and hot technologies in various sub-sectors are highlighted. Unfortunately, more patented technologies have not achieved a real breakthrough in the application.
