What is it indicated for?
The Strata NSC Valve is a shunt component designed to provide continued Cerebrospinal Fluid (CSF) flow from the ventricles of the brain to the right atrium of the heart or the peritoneal cavity. The design allows the physician to non-invasively adjust valve pressure/performance level pre- and post-implantation by using a special magnetic adjustment tool.
Indications for use as stated in the FDA 510(k) statement.
