JOSTENT冠脉覆膜支架

The Jostent coronary stent graft (CSG) is composed of a PTFE layer sandwiched between two stainless steel stents, initially introduced for the treatment of coronary perforations and aneurysms with excellent results. By providing a mechanical barrier, this stent design also may be beneficial in the treatment of complex ulcerated lesions and in-stent restenosis by preventing debris protrusion and neointimal proliferation through the stent struts.

冠状动脉支架(CSG)是由夹在两个不锈钢支架之间的聚四氟乙烯层组成，最初用于治疗冠状动脉穿孔和动脉瘤，效果很好。通过提供一个机械屏障，这种支架设计也可能有利于治疗复杂的溃疡性病变和支架内再狭窄，通过支架支柱防止碎片突出和新内膜增生。
