US 2010/0145133 A1 · IMPLANTABLE HEART ASSIST SYSTEM AND METHOD OF APPLYING SAME

Abstract

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.

Claims16

Dependent claims

A method for supplementing the circulation of blood through a patient without connecting any component to the patient's heart, the method comprising the steps of:

providing a pump having an inflow conduit and an outflow conduit;
providing fluid communication between a distal end of the inflow conduit and a first blood vessel that is not a primary blood vessel using a minimally invasive surgical procedure to permit the flow of blood to the pump from the first blood vessel;
inserting a cannula coupled with the outflow conduit into a second blood vessel that is not a primary blood vessel using a minimally invasive surgical procedure to permit the flow of blood away from the pump to the second blood vessel;
operating said pump to perfuse blood through the patient's circulatory system at volumetric rates that are on average subcardiac.
