Abstract: A cranial shunt implantable into a patient, the cranial shunt may comprise a first catheter, a second catheter and a valve assembly operatively coupled with the first and second catheters, the valve assembly comprising an inlet and a microcontroller, wherein the first catheter transfers cerebrospinal fluid (CSF) to the inlet. The cranial shunt may also comprise a pressure sensor configured to provide intracranial pressure (ICP) of the patient to the microcontroller, and a tilt sensor configured to provide an angle of orientation relative to gravity of a cranium of the patient to the microcontroller, where the valve assembly passes or blocks the CSF flow to the second catheter based on instructions from the microcontroller.
