ABSTRACT:
Apparatus for allowing excessive cerebrospinal fluid to drain from within the ventricles of a patient's brain. A hollow tube runs from a typical intraventricular device to a collection bag supported from a base at a selected elevation. The intraventricular device is hollow and is inserted into the ventricles of the patient's brain to allow cerebrospinal fluid to pass from the ventricles of the patient's brain to the intraventricular device, tube and base and into the collection bag. A concentric manometric device is provided to control the pressure of the cerebrospinal fluid passing from the intraventricular device to the collection bag and to allow the patency of the apparatus to be quickly and easily ascertained. Indicia is provided on the base for indicating when the base is properly positioned relative to the ventricles of the patient's brain so that there is no substantial difference in pressure between the collection bag and the ventricles of the patient's brain due to a difference in elevation between the collection bag and the ventricles of the patient's brain.
