A paracorporeal respiratory assist lung is configured with an annular cylindrical hollow fiber , membrane (fiber bundle) that is rotated at rapidly varying speeds. Fluid (for example, blood) , is introduced to the center of the device and is passed radially through the fiber bundle. The , bundle is rotated at rapidly changing velocities with a rotational actuator (for example, a , motor or magnetic coupling). The rotation of the fiber bundle provides centrifugal kinetic , energy to the fluid giving the device pumping capabilities and may create Taylor vortices to , increase mass transfer. Rotation of the fiber bundle increases the relative velocity between , the fluid and the hollow …
