PROBLEM TO BE SOLVED: To provide a method and an apparatus for shunting fluid to treat hydrocephalous, and in particular for treating normal pressure hydrocephalous, or Alzheimer's, Idiopathic Intracranial Hypertension (IIH), or any other condition in which it is necessary to drain and/or cleanse CSF (cerebrospinal fluid). SOLUTION: The methods and devices utilize a shunt 10 having a CSF inlet port 12i, and a CSF outlet port 14o, and a flow control component 16 for controlling CSF fluid flow from the CSF inlet port 12i to the CSF outlet port 14o. The shunt 10 can be implanted at a location V along or within a patient's spinal column. In one exemplary embodiment, a CSF inlet port of a shunt can be implanted within the subarachnoid space, and an outlet port of a shunt can be implanted at a drainage site. The cerebrospinal fluid is drained into the epidural space. COPYRIGHT: (C)2007,JPO&INPIT
