The present invention concerns a spinal fluid driven artificial organ device and methods for its use. The device has a tripartite chamber with three sections. A micropore filter ("B") separates chamber section 1 from chamber section 2 and a micropore filter ("C") separates chamber section 2 from chamber section 3. CSF enters chamber section 1 via an inlet tube (T.i.) and an one way value (V1). Micropore filter "B" allows entry of CSF into chamber section 2 but does not allow exit of any cells from chamber section 2 into chamber section 1. Micropore filter "C" allows free passage of CSF from chamber section 2 into chamber section 3 and prevents any cells in chamber section 2 from entering chamber section 3. The CSF flow exits chamber section 3 via an one way valve (V2) and an outlet tube (T.o.). The outlet tube (T.o.) delivers the CSF to the desired location.
