Abstract
The present invention operates to significantly reduce over or under drainage of cerebrospinal fluid (CSF) from the brain or spinal cord using an extraventricular drain (EVD) in the brain or lumbar drainage device (LDD) and automated intracranial pressure (ICP) monitoring. The present invention attaches the drainage catheter of the EVD to a flow controller or valve which controls the flow of CSF from the drainage catheter and is electronically controlled by a stepper motor communicating with a pressure transducer receiving pressure signals indicating an ICP without the need for constant manual re-leveling.
