Abstract
A low priming volume centrifugal pump comprising a disc shaped impeller having opposite faces and an inlet hole centrally disposed therein. The impeller has flow channels disposed on at least one of the faces of the impeller which radiate outward from said inlet hole. The volume of the flow channels is small relative to the total impeller envelope volume providing for efficient momentum transfer with a minimum of turbulence and backflow Thus, priming volume is reduced and flow within the pump is more efficient. The pump can be used as stand alone device, or it can be integrated with a blood oxygenator into a common housing.
