## Indications for use
The LiquoGuard CSF system is indicated for the external drainage of cerebrospinal fluid (CSF). It connects to any drainage catheter (not part of the product) which is usually inserted by the doctor into the lateral or third ventricle of the brain or lumbar subarachnoid space in selected patients to reduce intracranial pressure. The LiquoGuard CSF system controls CSF pressure using pressure sensors and a pump, thus taking the role of the conventional CSF dripping chamber and collection bag (predicate devices). The LiquoGuard CSF system also monitors intracranial pressure up to 75 mmHg and cerebrospinal fluid flow during CSF drainage, and provides many alarm functions not offered by the passive dripping chamber systems.
