What is it indicated for?
The StrataMR II Valves and shunts are designed to provide continuous Cerebrospinal Fluid (CSF) flow from the ventricles of the brain into the right atrium of the heart or the peritoneal cavity. The design enables the physician to non-invasively adjust valve pressure/performance level pre-and post-implantation by using magnetic adjustment tools without the need of radiographic confirmation.
