Abstract
Disclosed herein is an implantable blood pump assembly that includes a housing defining an inlet, an outlet, a flow path extending from the inlet to the outlet, and an internal compartment separated from the flow path. The blood pump assembly further includes a rotor positioned within the flow path and operable to pump blood from the inlet to the outlet, a stator positioned within the internal compartment and operable to drive the rotor, and an inlet conduit connected to the housing inlet and having a downstream end that has a reduced cross-sectional area that produces a localized region of high velocity blood flow. The blood pump assembly further includes at least one pressure sensor positioned between the inlet and the outlet and configured to detect a pressure of blood flowing through the flow path. The pressure sensor is located adjacent the downstream end of the inlet conduit.
