Elements of the left ventricular assist device. The inflow cannula is fixed into the left ventricle. The outflow conduit interjoins the ascending aorta. The technology of the pumping chamber is engineered to withdraw blood, which has returned from the lungs and entered the left ventricle, subsequently pumping it through the outflow graft into the ascending aorta, which is then supplied to the body. The driveline rests percutaneously, holding the battery and system controller, supported by a shoulder strap.
