A system and/or a method of evacuating cerebrospinal fluid (CSF) from a CSF reservoir is provided. The system can include a CSF reservoir, a reservoir mating piece, and a securing piece. The reservoir mating piece can have a tip end configured to be insertable into the CSF reservoir and a drainage end configured to be coupled to a drainage tube, the reservoir mating piece forming a drainage passageway for the evacuation of CSF from the CSF reservoir. The securing piece can be configured to be affixed to an individual's skin. In an unlocked position, the securing piece may be configured to slide along the reservoir mating piece, and in a locked position, the securing piece may be configured to be fixed relative to the reservoir mating piece. At least a portion of the drainage passageway is nonlinear between the tip end and the drainage end.
