ABSTRACT:
Methods and devices are provided 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. The methods and devices utilize a shunt having an inlet port, and outlet port, and a flow control component for controlling fluid flow from the inlet port to the outlet port. The shunt can be implanted at a location along or within a patient's spinal column. In one exemplary embodiment, an 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. In certain exemplary embodiments, the cerebrospinal fluid is drained into the epidural space.
