A central nervous system drain drains the subdural space intracranially or the postoperative epidural space in the spine. The drain includes one or more lumens that communicate with the outside environment through openings in the distal portion of the drain. The drain also includes a flat bottom wall without any openings which is placed on the brain surface in the subdural space intracranially or the epidural surface in the spinal canal after a laminectomy. The openings in the top wall and/or side surface walls allow for drainage of fluid and/or blood in the subdural space or postoperative wound in the spine.
