The PS Medical Strata valve is a programmable shunt valve used in the treatment of hydrocephalus that allows for noninvasive changes in the pressure setting using a magnet. The Strata valve is sensitive to magnetic fields, and reprogramming is frequently necessary after MR imaging. A known but rare complication of the Strata valve is that the rotor can become locked, causing shunt malfunction. This complication can only occur in a first generation Strata valve.
PS Medical Strata分流阀是一种用于治疗脑积水的可编程分流阀，它允许使用磁铁对压力设置进行无创更改。Strata阀对磁场敏感，在磁共振成像后通常需要重新编程。Strata阀一种已知但罕见的并发症是转子可能会锁定，导致分流器故障。这种并发症仅会发生在第一代Strata阀中。
