  • Patent number: 12005215
    Abstract: The application relates to a hydrocephalus valve for draining CSF from the ventricle systems of patients. The valve has a housing with a housing interior and at least one first passage for admission and/or discharge. The valve has at least one body provided in the housing interior. The body is designed to move in at least one direction. At least one adjusting unit is provided. The application aims to improve tried-and-tested existing valves. To achieve this, the adjusting unit is designed to adjust at least one drainage rate in the passage, and to allow the drainage rate to be adjusted between 1 ml per hour and 1000 ml per hour at a pressure at the hydrocephalus valve of 20 cm water column, in order to slow or accelerate, by means of this adjustment, a change in pressure in the ventricle system that results from the drainage.
