The paper presents the setup and the results of examinations of the input impedance in the silicon models of the common carotid artery bifurcation without stenosis and with 90 % stenosis of the internal carotid artery branch. The input impedance measured in the models is compared with impedance calculated on the base of the values of the hydraulic model elements and of the model load. As a criterion of determination is used the difference between the measured flow and the flow evaluated on the basis on the calculated impedance in the carotid artery bifurcation models. There was no significant difference between the measured and calculated input impedances in the ease of the non-stenosed internal carotid artery. A significant difference between measured and calculated impedances was found for the model of bifurcation with the stenosis of the internal carotid artery. Reflections of pressure wave from the stenosis are expected to be the reason of this effect.
