    Abstract: An external slot valve for controlling blood flow through the outlet of a shunt of a cardiopulmonary bypass pump wherein a valve seat having a knife edge is fixedly connected to the fixed plate of the bypass pump, and a valve head having a knife edge is pivotally connected to the fixed plate. The valve head is spring biased to the closed position against the valve seat to pinch the shunt extending therethrough. When in the open position, the knife edges provide a slot forming a large orifice for the blood to flow through the outlet of the shunt to diminish the work of the pump and reduce trauma to the blood.

    Abstract: A fluidic device comprises a first channel conduit, a valve apparatus, and an additional element adjacent to the first channel conduit. The first channel conduit transports fluid from a first fluid entrance to a fluid exit. In one embodiment, the additional element is a pump chamber that receives fluid from a second fluid entrance and pumps fluid into the first channel conduit in accordance with fluid pressure. Alternatively, the additional elements include a second channel conduit and a neck of the first channel conduit. The first channel conduit and the second channel conduit share a common wall. Fluid pressure in the first channel conduit controls a valve apparatus. The value apparatus controls a rate of fluid flow in the first channel conduit by deforming the common wall to change a cross-sectional area of the neck, which changes a rate of fluid flow in the second channel conduit.
