Abstract
An extracardiac pumping system (10) for supplementing the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart. One embodiment and application of the extracardiac system comprises a pump (32) that may be implanted subcutaneously at or about the patient's femoral artery in a minimally-invasive procedure, wherein the pump is powered by a battery (44) and a mechanism for charging the battery extracorporeally, whereby the pump draws blood through an inflow conduit (50) fluidly coupled to the patient's femoral artery via, for example, a subcutaneous anastomosis connection, and discharges blood through an outflow conduit (52) fluidly coupled to a second peripheral artery via, for example, a subcutaneous anastomosis connection. The pump may be operated in continuous flow mode, or in a pulsatile fashion synchronous with the patient's heart, thereby potentially reducing the afterload of the heart.
The conduits (50, 52) can be placed in fluid communication with a multi-lumen catheter (510) for single point application of the system to the patient. If desired, a reservoir (410) may be provided fluidly communicating with the inflow conduit. The system may also comprise a device (402) for maintaining at or near body temperature the blood travelling extracorporeally within the system. If further desired, the present system may be carried directly on the patient with a device (610) that holds at least the pump and is carried by a belt or a shoulder strap.

The system may also comprise a device (402) for maintaining at or near body temperature the blood travelling extracorporeally within the system. If further desired, the present system may be carried directly on the patient with a device (610) that holds at least the pump and is carried by a belt or a shoulder strap.
