Abstract
An implantable intracranial pulse pressure modulator for treating hydrocephalus in patients of all ages is disclosed as well as a system and method for use of the same. In one embodiment of the implantable intracranial pulse pressure modulator, two one-way valves are interposed in parallel, opposing orientations between a vestibule and a chamber. One of the one-way valves, in response to systole, provides fluid communication from the vestibule to the chamber such that a small aliquot of cerebrospinal fluid (CSF) is displaced from a cerebral ventricle into a ventricular catheter, thereby reducing intraventricular systolic pressure. The other one-way valve, in response to diastole, provides fluid communication from the chamber to the vestibule such that the same volume of CSF is reintroduced into a cerebral ventricle, thereby increasing intraventricular diastolic pressure. Together, both processes work synergistically to reduce intraventricular pulse pressure in order to treat hydrocephalus.
