title: A theoretical study of new types of valve shunts for cerebrospinal fluid.
abstract: Two new solutions for cerebrospinal fluid (CSF) valve shunts are described. The first is based on the principle of multihole flow, and the second, which is less complex mechanically, is based on the action of elastic elements on a ball-cone valve.
