Abstract

A pulsatile blood pump including a chamber having an upstream portion, a downstream portion, and a wall coupling the upstream portion to the downstream portion, the upstream portion defining an inlet sized to fit within a ventricle of a heart, the downstream portion defining an outlet, and the wall defining a bore; a piston disposed within the bore of the wall, the piston including a first side in continuous fluid communication with the ventricle of the heart when the inlet is within the ventricle of the heart and defining a travel path within the bore including an upstream direction toward the inlet and a downstream direction toward the outlet; and a valve coupled to the piston and defining a one-way fluid flow path within the chamber through the first side of the piston in the downstream direction.
