The Strata valve diverts excess cerebrospinal fluid (CSF) from the ventricles of the brain to another area of the body – usually the peritoneal cavity or right atrium of the heart. The Strata valve uses a patented technology that utilizes a magnetic rotor to adjust the tension on a ball and spring valve mechanism, allowing for five separate pressure/flow performance level settings. The pressure/flow performance level setting can be changed non-invasively by using one of the Strata Adjustment Systems, which use magnets to change the pressure/flow performance level and sensors to verify the new setting.

The Strata valve also includes a siphon-control device, the Delta® Chamber. This device is a normally closed mechanism which opens in response to positive ventricular pressure, but stays closed in response to ...
