Abstract

A non-invasive method of measurement and analysis of the arterial input impedance of the carotid artery was applied to silicone models of the normal and stenosed carotid bifurcation. The experimental setup enabled the simulation of in vivo conditions. The experimental results were compared with impedance computed for a lumped element electrical model and a model containing transmission line elements. The stenosis resulted in increased impedance moduli and phase values. Similar phenomena were observed for both computational results. However, the transmission line model yielded phase plots closer to the experimental ones. The method of measurement and analysis of the arterial input impedance appears to be an efficient tool for the assessment of the properties of the carotid bifurcation.
