Abstract
The invention provides means by which access to the intracranial compartment is completely sealed from the skin and the scalp tissues, which makes it possible to change the drain when necessary without bringing the drain in the contact with the scalp. It also provides an improved ventricle draining system supporting a better fixation of the drain to avoid the drain from sliding. The drain comprises a fixture with a conduit defining passage through the fixture, the fixture being provided with fastening means for attachment of the fixture to an aperture in the cranial bone, a seal for sealed engagement with a catheter inserted in the fixture, and fastener for securing the catheter to the fixture.
