To study the influence of a newly developed membrane stent design on flow patterns in a physiologic carotid artery model. Three different stents were positioned in silicone models of the carotid artery: a stainless steel stent (Wall-stent), a nitinol stent (SelfX), and a nitinol stent with a semiper...
