Advancement of bioabsorbable coronary stents / 中国组织工程研究

ABSTRACT

The problem of subacute thrombosis and restenosis iS still not being resolved with stainless steel and cobalt-chromium alloy-based drug-eluting stent fundamentally.Therefore,the bioabsorbable stent has become the focus of attention.At present,the main component of the bioabsorbable metal stent studying in clinic is magnesium alloy,including 93%magnesium,7%REE(rare-earth elements).It has a new endothelial recovery fast,low-induced thrombosis and the degradation of suitable time(2-3 months),and other advantages.The bioabsorbable coronary stent is the future direction of stent development.
