Abstract: A ventricular assist device includes a stent for placement within a cardiac artery and arranged for placement, the stent arranged to have an open configuration defining a flow path, a rotor sized to fit within the stent and arranged for percutaneous placement the flow path, the rotor including a surface disposed about a central portion and angled with respect to the flow path and having a first plurality of magnets. A collar is sized for placement about the cardiac artery and includes a stator. A power source is coupled to the stator, and the stator and the rotor are arranged to rotate the rotor about an axis. A timing control module controls a rotational speed of the rotor. Accordingly, the surface of the rotor is arranged to move blood along the flow path in response to rotation of the rotor.

Abstract: A ventricular assist device including a frame having a proximal end and an outer surface, and an anchor having a base and a brace coupled to the base. The base is attached to the proximal end of the frame. The device also includes a stator assembly coupled to the frame, a rotor assembly disposed between the stator assembly and the frame, and a power source operatively coupled to the stator assembly. The anchor is moveable between a collapsed configuration in which an inner surface of the brace contacts the outer surface of the frame, and an expanded configuration, in which the inner surface of the brace is offset from the outer surface of the frame and an outer surface of the brace engages a portion of the blood vessel to secure the frame within the blood vessel.
