Flow Modelling of POLVAD-MEV Ventricular Assist Device in the Apex of the Heart-Artery Configuration

Abstract

The paper presents flow modelling method for pulsatile heart support devices working in the apex of the heart-artery configuration. It describes the measurement stand, which consists of ventricular assist device working in connection with hybrid simulator of cardiovascular system. The method of model development is presented and explained. The results obtained for different cases of pump operation and simulated patient conditions are included. Resulting description of the artificial ventricle seems to be independent of hemodynamic conditions or control parameters of the pump. 
