Abstract

Mechanical circulatory supports configured to operate in series with the native heart are disclosed. In an embodiment a centrifugal pump is used. In an embodiment inlet and outlet ports are connected into the aorta and blood flow is diverted through a lumen and a centrifugal pump between the inlet and outlet ports.
