Bioresorbable metal scaffold for cardiovascular application: Current knowledge and future perspectives

摘要

Over the last decade, the introduction of drug-eluting stents has dramatically reduced restenosis and the need for repeat revascularization after implantation of metallic stents. Numerous concerns still remain, however, because of their permanent nature. Thus, the concept of bioresorbable temporary scaffolds composed of biocompatible materials has emerged as a potential alternative to permanent metal stents. Here we focus on metal alloys & discuss preclinical and clinical experiences with bioresorbable metal scaffolds.
