A ventricular assist device includes a pump such as an axial flow pump, an outflow cannula connected to the outlet of the pump, and an anchor element. The anchor element is physically connected to the pump, as by an elongated element. The pump is implanted within the left ventricle with the outflow cannula projecting through the aortic valve but desirably terminating short of the aortic arch. The anchor element is fixed to the wall of the heart near the apex of the heart so that the anchor element holds the pump and outflow cannula in position. 1. (canceled)2. A blood pump for intraventricular placement inside a heart of a mammalian subject comprising:a rigid elongate member defining a major longitudinal axis having a length between proximal and distal ends and a bore extending along the length;an anchor element connected proximate the proximal end of the rigid elongate member and mountable to the subject's heart; anda pump defining a pump axis and including an inlet at a first end and an outlet at a second end, the inlet and outlet being positioned along the pump axis, a rotor defining a rotor axis coincident with the pump axis and including at least one electric drive coil spaced laterally from the pump axis and the rotor axis for magnetically driving the rotor, the pump being coupled proximate the distal end of the rigid elongate member and remote from the anchor element, the rotor axis and the pump axis being offset from the member axis.3. The pump of claim 2 , further comprising wire extending through the bore of the pump claim 2 , and wherein the proximal end of the rigid elongate member includes a fitting through which the wiring passes into the bore of the rigid elongate member.4. The pump of claim 3 , wherein the wiring extends from a source of electrical power claim 3 , through the fitting of the rigid elongate member claim 3 , through the bore of the rigid elongate member claim 3 , and to the at least one electric drive coil to drive the rotor of the pump ...
