查询词典 composites

The mechanical property testing shows that the seamless PLLA tubes perform excellent radial strength,which indicates that the mechanical properties of biodegradable stents made of these tubes was supposed to be excellent.PLLA and its composites were first used in preparing seamless tubes as antecedency of laser-cut biodegradable coronary stents in china.Finite element analyses of the biodegradable coronary stent model indicate the explorative design basically meets the requirement of reasonable and applicable stents.There is not such kind of research yet in domestic.Optimum laser-cuttting parameters of CO2 laser was cauculated based on experiential formula,within it,biodegradable coronary stents,especially those with complex structure would be manufacutured from seamless tubes quickly by laser microprocessing with high consistency to the design model.The processing efficiency of the CO2 laser demonstrated in experiential formula by us will play an important guiding role in manufacturing biodegradable stents by laser-processing.Our stents that ascribed to laser-cutted,slotted tube stent are proved to be biodegradable, self-expandable and good biocompatible,basically reach the international level on the aspest of manufacturing procedures and design.
