Abstract

The location of the inflow cannula of the left ventricular assist device (LVAD), which is inserted into the left ventricle at the apex, has a great influence on the flow pattern inside the left ventricle. The design parameters of the inflow cannula have been numerically optimized in order to prevent the thrombus formation in the left ventricle for a prolonged use of the LVAD.
