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.

摘要： An extracardiac pumping system and method for using it supplement the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart. A battery powered pump may be implanted subcutaneously and attached to an inflow conduit fluidly coupled to a patient's femoral artery via a subcutaneous anastomosis connection. The pump draws blood from the inflow conduit and discharges it through an outflow conduit fluidly coupled to a second peripheral artery via another subcutaneous anastomosis connection. The battery may be charged extracorporeally and the pump may be operated in either a continuous or pulsatile fashion in synchronization with the patient's heart. The conduits can be housed in a multi-lumen catheter and a reservoir may be provided which fluidly communicates with the inflow conduits. An additional feature may keep blood traveling extracorporeally within the system at or near body temperature. The system is capable of adjusting outflow from the pump to optimize the mixing of red blood cells in the aorta and thereby enhance oxygen delivery to tissues by minimizing blood cell concentration in the center of the aorta.

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 a pump configured to be implanted subcutaneously in a minimally-invasive procedure, wherein the pump can draw blood through an inflow conduit, and can discharge blood through an outflow conduit. 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. The conduits can be housed in a multi-lumen catheter.

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 methods of using same. One embodiment provides a vascular graft that has a first end that is sized and configured to couple to a non-primary blood vessel and a second end that is fluidly coupled to a pump to conduct blood between the pump and the non-primary blood vessel. An outflow conduit is also provided that has a first end sized and configured to be positioned within the same or different blood vessel, whether primary or non-primary, through the vascular graft. The outflow conduit is fluidly coupled to the pump to conduct blood between the pump and the patient. The vascular graft may be connected to the blood vessel subcutaneously to permit application of the extracardiac pumping system in a minimally-invasive procedure.
