Intracerebral sensor catheter

Neurosurgical pressure catheters directly measure brain parameters including intracranial pressure, oxygen partial pressure of interstitial fluid, and brain temperature , with some versions capable of measuring up to three parameters simultaneously whilst also enabling cerebrospinal fluid drainage . These invasive devices are used in neurosurgery to monitor critical brain physiology , with applications in intracranial pressure monitoring and cerebrospinal fluid drainage in patients requiring direct intraventricular pressure assessment .
