Abstract
The present invention, in one embodiment, is a blood pump for intraventricular placement inside a heart of a mammalian subject including a rigid elongate member having a length between proximal and distal ends and a bore extending along the length, an anchor element connected towards the proximal end of the rigid elongate member and mounted to the subject's heart, a pump having an inlet and an outlet, a rotor and at least one electric drive coil for magnetically driving the rotor, the pump connected at or adjacent to the distal end of the rigid elongate member remote from the anchor element and wiring extending through the bore to the pump, wherein the proximal end of the rigid elongate member extends past the anchor element to a position outside of the subject's heart. Additional embodiments of a blood pump, and various methods of intraventricular placement inside a heart of a mammalian subject are also considered.
