Abstract
The flow field of the newly developed inflow cannula designed for a bridge-to-decision circulatory support was numerically analyzed by computational fluid dynamics. This new cannula has elastic struts at the cannula tip that enables minimal invasive insertion to the left ventricle, while keeping a wide inflow area by its lantern-like cannula tip. The hydrodynamic loss of the cannula, including the change in pressure loss due to deformation, and the thrombus potential of the cannula were numerically examined. The hydraulic resistance of the cannula with the blood analog fluid was 31 mmHg at the flow rate of 5.0 L/min.
