Abstract
Fluid dynamics in two different stent configurations, peak-to-valley (S1) and peak-to-peak (S2), within a fully expanded situation and a 30% restenosis is investigated. Numerical simulations are carried out in order to evaluate the conditions promoting atherosclerotic events when a self-expanding bare metal stent is applied. The conclusions are that the two configurations, S1 and S2, have a similar fluid dynamics behavior as far as wall shear stress is concerned, but oscillatory shear and relative residence time maps suggest that the peak-to-peak configuration, S2, has a better behavior than the peak-to-valley, S1.
