Abstract: A system for assisting a circulation of blood inside a body of a patient includes a pump including: a housing having an upstream portion and a downstream portion; an inducer positioned in the upstream portion of the housing, the inducer including one or more helically-wound inducer blades to rotate around a longitudinal axis of the pump; an impeller positioned downstream of the inducer in the housing, the impeller including one or more impeller blades to rotate around the longitudinal axis of the pump; and a diffuser positioned in the downstream portion of the housing, to direct blood through at least one aperture in a circumference of the housing.

Abstract: Disclosed are systems, devices, and methods that employ a pump to assist or support blood flow. An apparatus for pumping blood may include a pump housing having an outerwall disposed about a longitudinal pump axis, and having an upstream end and a downstream end; a blood flow straightener having a plurality of fins and positioned in the upstream end of the pump housing and secured to the pump housing by the plurality of fins; a diffuser having a plurality of diffuser fins and positioned in the downstream end of the pump housing and secured to the pump housing by the plurality of diffuser fins; and an impeller positioned between the blood flow straightener and the diffuser, and including a plurality of impeller blades. The apparatus may further include a pump drive configured to impart a rotational motion to the impeller by applying a magnetic field.
