Medtronic PS Medical Adjustable Strata Valves

This page was last updated on September 17th, 2017

The Medtronic Strata® valve is an adjustable ball and spring valve. The tension of the valve’s spring can be altered utilizing a magnetic rotor mechanism integral to the valve. This adjustment is made non-invasively utilizing the hand-held StrataVarus adjustment tool to alter the magnetic rotor’s position and thus tension of the valve’s spring. The Strata NSC contains the adjustable pressure differential ball and spring valve while the Strata II also contains a Delta siphon control device.
