An implantable cerebral spinal fluid flow device and method. A body has an inlet for the cerebral spinal fluid, an outlet for the cerebral spinal fluid and a first interior cavity fluidly coupled with the inlet and the outlet. A first rotational element is mounted in the first interior cavity in a pathway between the inlet and the outlet. The first rotational element provides resistance to flow of the cerebral spinal fluid from the inlet to the outlet. In the method, the cerebral spinal fluid flow device is implanted. Resistance to rotation of the first rotational element to flow of the cerebral spinal fluid from the inlet to the outlet is provided.
