Multifunctional MgF2/Polydopamine Coating on Mg Alloy for Vascular Stent ApplicationXiaoli Liu1,Zhen Zhen2,Jing Liu2,Tingfei Xi1,2,3,Yudong Zheng1,Shaokang Guan4,Yufeng Zheng2,Yan Cheng21. School... is of great potential in the application of vascular stent due to its degradation in physical environment and proper mechanical property.However its mechanical integrity does not meet the clinical......
="ChDivSummary">Polymer coating was widely used as a protective coating on Mg alloy stent due to its excellent deformability. However, the polymer coating with lots of macro-and micro-holes after solvent evaporation during forming process would make corrosion medium permeate easier and decrease the corrosion resistance of Mg alloy stent. In this study, a novel critical re-melting method was adopted......
Assessment of structure integrity, corrosion behavior and microstructure change of AZ31B stent in porcine coronary arteriesShanshan Chen1,Bin Zhang2,Bingchun Zhang1,Hao Lin1,Hui Yang1,Feng... alloy coronary stent becomes a hot research topic due to its biodegradable character for avoiding late thrombosis and late restenosis. However, fracture of Mg alloy stent was a common issue after......
Inhibition of Bacterial Adherence on the Surface of Biliary Stent Materials Modified With Chitosan刘恒全,黄楠Key Laboratory of Advanced Technology of Materials, Chinese Education Ministry, School.... Bacterial adherence and biofilm formation on the surface of a material have been considered as one of the main factors of stent re-occlusion in clinic. This work reported preventing bacterial adherence......
