FIELD: medicine.
SUBSTANCE: invention relates to medicine and can be used for removal of fluid from brain ventricles into other part of body. Device contains inlet and outlet holes; and resistance-generating element, which contains first plate, with a groove on its surface and second plate. Second plate is pressed to the surface with groove in such a way that it forms resistance-generating duct, its inlet being hydraulically connected with inlet hole. Duct contains, at least, two outputs along its length, each of which can be hydraulically connected with outlet hole by means of switching device in order to change working length of resistance-generating duct, each of which contains a hole in first or second plate. Holes are blocked or are not blocked by switching device. Switching device contains rotor, installed near resistance-generating element and possessing through canal. Rotor is installed in device for rotation relative to resistance-generating device and is made with possibility of magnetic excitation.
EFFECT: ensuring correct rotor orientation in absence of its direct visibility.
