The present invention provides a cerebrospinal fluid shunt system that monitors the intracranial pressures over a portion of a monitoring cycle to calculate short intervals of drainage for every monitoring cycle necessary to produce the desired pressure correction. The system operates to significantly reduce the time during which draining occurs allowing tissue surrounding the catheter to rebound from the catheter holes returning to its normal position for a sufficient amount of time to recover its normal shape.

Cerebrospinal-fluid shunt valve system

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.
