摘要: An apparatus and method for reducing backflow in a heart pump device are disclosed. In one configuration, ventricular assist (VAD) has connected to ventricle of the by an inflow cannula blood vessel outflow cannula. The VAD is designed such manner that overall reactance comparatively high, thereby incidence time-varied flows, as backflow, through VAD. Resistance steady state flow may simultaneously be maintained below threshold level provide low-power operation. desired resistance properties obtained adjusting or both cannulae. set at tuning more geometric characteristics cannula, including bore diameter, length, cross sectional shape, compliance
