Methods and apparatus for treating hydrocephalus caused by obstructions in the ventricular system and subarachnoid space of the brain. Embodiments include medical devices and methods for use within the subarachnoid space of the central nervous system to gain access to and treat an obstruction within the ventricles of the brain or a subarachnoid hemorrhage. The obstruction may be aspirated by an aspiration catheter for use in the subarachnoid space. A subarachnoid delivery catheter may then be used to deliver an intraventricular shunt to the opening in the obstruction via the subarachnoid space. A distal end of the delivery catheter is navigated across the obstruction to deploy the intraventricular shunt therein. The intraventricular shunt so positioned reopens the pathway between the ventricles and permits the return of normal cerebrospinal fluid flow there through.
