Examination of Drug-eluting Coatings of Coronary Artery Stents

Open access

Abstract

Drug-eluting stents provide a solution for treating restenosis in arteries expanded by using conventional bare metal stents, but there are a small number of publications on the processes of coating damage established due to the various effects that occur during the life cycle of the stent. In the current research damage to the coating was investigated along with the effects of damage on the corrosion resistance of the stent in multiple ways. This research investigates not only traditional drug eluting stents with polymer matrix, but also the new generation of polymer-free types.
