    摘要: An extracardiac pumping for supplementing the circulation of blood through a patient without any component thereof being connected to the patient's heart, and method of using same. The extracardiac system comprises a pump implanted subcutaneously at or about the patient's groin in a minimally-invasive procedure, wherein the pump is powered by a battery, and means for charging the battery extracorporeally, wherein the pump draws blood through an inflow conduit fluidly coupled to the patient's femoral artery via a subcutaneous anastomosis connection, and discharges blood through an outflow conduit fluidly coupled to a peripheral artery that stems from the patient's aortic arch via a subcutaneous anastomosis connection. The pump may be operated continuously or in a pulsatile fashion, synchronous with the patient's heart, thereby potentially reducing the pumping load on the heart.

    摘要: An extracardiac pumping for supplementing the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart, and method of using same. One embodiment of the extracardiac system comprises an implantable or portable subcardiac pump, whereby the pump draws blood through an inflow conduit fluidly coupled to a non-primary artery via a cannula and discharges blood through an outflow conduit fluidly coupled to a second non-primary artery via a cannula, wherein at least one of the cannulas projects well into the patient's vascular system. The pump may be operated continuously or in a pulsatile fashion, synchronous with the patient's heart, thereby potentially reducing the afterload of the heart.
