Claim:
1. An endovascularly implantable shunt device for draining cerebrospinal fluid from a patient's subarachnoid space, the device comprising: a shunt having opposed first and second ends, the second end being constructed to penetrate a wall of a dural venous sinus of the patient; a one-way valve located between the first and second ends of the shunt; a hollow passageway extending between the second end and the one-way valve such that cerebrospinal fluid can be drained through the second end and out through the valve into the sinus; a stabilizing mechanism coupled to the shunt and configured to apply a constant outward radial force and anchor the shunt against an inner wall of the dural venous sinus at a desired location proximal to the subarachnoid space; and a shielding mechanism coupled to the shunt and sized and configured to shield a portion of the shunt implanted in the subarachnoid space from surrounding brain parenchyma tissue.
