Abstract: A centrifugal pump includes a system that removes gas that accumulates along the axis of rotation of the shaft and/or impeller of the pump. One or more vent inlets are placed in the region where the gas accumulates and a suction device draws the accumulated gas through the vent inlets and a vent out of the centrifugal blood pump.

Abstract: A two-chambered centrifugal blood pump for pumping biological fluids such as blood. One chamber is for pumping blood through the natural lungs, and a second chamber is for pumping blood through the remainder of the body. Each chamber has it's own inlet and outlet ports for attachment of tubing and cannulae. A small, adjustable clamp may alternatively be provided if minor adjustments of pressure to both the pulmonary and systemic circuits is required.
