1. A device for regulating cerebrospinal fluid in a cerebrospinal fluid space comprising:

  • a cerebrospinal conduit having a distal end for insertion into the cerebrospinal fluid space in fluid communication with the cerebrospinal fluid;

    an actively oscillatably changeable sealed fluid volume in fluid communication with the cerebrospinal conduit, the changeable sealed fluid volume being within an enclosed container, the container containing at least one of cerebrospinal fluid and saline fluid therein, a deformable fluid tight balloon having interior and exterior surfaces extending into the container, the balloon for expanding and deflating in volume size within the container for decreasing and increasing fluid volume size of the changeable sealed fluid volume, the container having a first port in communication with the changeable sealed fluid volume, the cerebrospinal conduit being coupled to the first port of the container, the changeable sealed fluid volume being in a sealed fluid path extending to the distal end of the cerebrospinal conduit and capable of actively oscillating in a changing fluid volume size for oscillating the cerebrospinal fluid in and out of the distal end of the cerebrospinal conduit and cerebrospinal fluid space; and

    pressure sensor elements positioned for sensing pressure within the chanegable sealed fluid volume and within the balloon for controlling oscillation parameters for oscillating the cerebrospinal fluid.
