Abstract
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.
