An<unk>  is an intraventricular catheter system that can be used for the aspiration of cerebrospinal fluid or for the delivery of drugs (e.g. chemotherapy) into the cerebrospinal fluid. It consists of a catheter in one lateral ventricle attached to a<unk>  implanted under the scalp. It is used to treat brain tumors, leukemia/lymphoma or leptomeningeal disease by intrathecal drug administration. In the palliative care of terminal cancer, an<unk>  can be inserted for intracerebroventricular injection (ICV) of morphine. It was originally invented in 1963 by Ayub K.<unk> , a Pakistani-American neurosurgeon. In January 2017, researchers at University of Texas Southwestern Medical Centre used an<unk>  to measure the intracranial pressure that is regularly observed in astronauts in zero-gravity conditions.<unk>  tool-1.png<unk>  tool-2.png
