Abstract
A method for pumping and oxygenating blood includes receiving a flow of gas including oxygen into a gas inlet manifold via a gas inlet. The flow of gas is passed through the hollow fibers from the gas inlet manifold to a gas outlet manifold. The flow of gas is output from the gas outlet manifold via a gas outlet. An impeller is rotated to generate a flow of blood that flows over the hollow fibers. Oxygen from the flow of gas is transferred to the flow of blood through the hollow fibers. Carbon dioxide is transferred from the flow of blood to the flow of gas through the hollow fibers.
