Abstract: An interventional ventricular assist device (100), including: an interventional tube (10). a motor assembly (30), a perfusion cylinder (40), and an impeller assembly (20). The interventional tube (10) has a liquid inlet (11) and a liquid outlet (12). The impeller assembly (20) includes an impeller (21), accommodated within the interventional tube (10) and rotatable to enable a liquid to flow into the interventional tube (10) via the liquid inlet (11) and out therefrom via the liquid outlet (12). The motor assembly (30) is configured to generate a rotating magnetic field to drive the impeller (21) to rotate and generate an attraction to the impeller (21). A perfusate injected from the perfusion cylinder (40) is adapted to provide a thrust to the impeller assembly (20), whereby the impeller (21) is suspendedly rotatable in the interventional tube (10) under a combined action of the thrust and the attraction.
