The present invention is directed to a blood aspiration system that is configured to enable various types of aspiration through a working lumen of a catheter. The blood aspiration system facilitates natural aspiration by providing a circuit between a patient's arterial and venous vasculature, and also comprises a manually actuated pump configured to selectively vary rates of aspiration in the working lumen. The blood aspiration system further comprises an external port that allows suction-assisted aspiration or infusion through the working lumen, and further comprises a detachable filter that removes emboli prior to reperfusing blood into a patient's venous vasculature.

Il comprend une pompe manuelle conçue pour moduler sélectivement les débits d'aspiration dans la lumière considérée. Enfin, il comprend un orifice externe qui assure l'aspiration ou l'infusion par succion à travers ladite lumière, et un filtre amovible qui permet d'évacuer les emboles avant la reperfusion du sang dans le réseau veineux du patient.
