Ommaya reservoir

Ommaya reservoir, also known as Ommaya shunt, is a device consisting of an intraventricular catheter connected to a reservoir (port) implanted beneath the scalp. It is used for intrathecal administration of medication such as chemotherapy (mainly in the treatment of meningeal lymphomas, but also for other meningeal pathology) and palliative analgesics, as well as for CSF aspiration.

It can also be used for aspirating large cystic brain tumors as part of combination therapy. 1
