Investigation of Coated Coronary Stents

Article Preview

Abstract:

In this study the main properties of coated coronary stents are shown, such as recoil, foreshortening, surface features and failures and the expansion properties. The types and the effects of active and passive coatings are introduced. The results of our examinations with different coated coronary stents are shown as well. The quality and the changing of the coatings were examined by different methods (stereomicroscopy, atomic force microscopy, scanning electron microscopy and EDS analysis).
