Comparative studies of different vascular stents in terms of mechanical performances: Finite element analysis

Abstract

Seven representative commercialized stents were evaluated by FE analysis in terms of the criteria based on the itemized list of Food and Drug Administration (FDA) and European Standards (prEN). Tenax and MAC standard were generally excellent in various evaluation items. Palmaz-Schatz was the most excellent in fatigue durability, but its flexibility was a little inferior than that of other stents. This study may suggest a guideline for improvement in stent design and function. © Springer-Verlag Berlin Heidelberg 2007.
