Systems and methods for controlling cerebrospinal fluid in a subject's ventricular system

摘要

A system for draining excess cerebrospinal fluid (CSF) from the head of a subject includes a drainage shunt and a valve assembly that selectively permits the shunt to drain CSF. The valve assembly also compensates for multiple factors that can affect the subject's intracranial pressure (ICP) and compliance, and could otherwise lead to CSF over-drainage or other undesirable conditions.
