A cerebral catheter device (22) for draining fluid from the brain of a patient is described. The device (22) may be used as part of a ventricular shunt system. The device (22) includes an elongate tube (24) for insertion into the brain of a patient to a vicinity of a desired target. A head (26) is attached to the elongate tube (24) that has a passageway (30) in fluid communication with a lumen of the elongate tube. Formations are provided on the external surface of the head (26) for securing the head in a hole formed in the skull of a patient. The head further comprises a first fluid connector portion (32) that is attachable to an associated drainage catheter device (34). This allows fluid communication to be established between the lumen of the elongate tube (24) and a drainage catheter device (34) via the passageway (30) of the head.
