These External Drainage Systems enable the Cerebrospinal Fluid (CSF) to drain from the brain's lateral ventricles. It also monitors these drainage levels. It also monitors the drainage from the lumbar sub-arachnoid space in order to decrease intracranial pressure (ICP) and to monitor cerebrospinal fluid and intracranial pressure. It also allows CSF to be temporarily drained. A pole mount may be assembled for additional support and to ensure the External Drainage Systems are properly aligned. These systems are compatible with Camino or Ventrix Ventricular Pressure Monitoring Kits.
