新一代药物洗脱支架由可吸收多聚物为平台,具有与金属支架相当的的支撑力,以及良好的生物相容性。既可以暂时支撑管壁,抑制早期血栓形成及晚期新生内膜增生,还可作为良好的药物载体实现局部控制释放,达到有效防止支架置入后的血管急性闭塞和降低再狭窄率。 The new generation of drug-eluting stents consists of an absorbable polymer-based platform with comparable support force to metal stents and good biocompatibility. Can support the wall temporarily, inhibit early thrombosis and advanced neointimal hyperplasia, but also as a good drug carrier to achieve local controlled release, to effectively prevent the stent after the insertion of the vascular occlusion and reduce the rate of restenosis.
