The disclosure relates to a cerebrospinal fluid (CSF) shunt for treatment of hydrocephalus, comprising a valve having an inlet port and an outlet port, which ports are for draining CSF, and a control port for regulating the drainage of CSF through the valve according to a hydrostatic pressure provided to the control port, which hydrostatic pressure is dependent on the body position of the patient. The disclosure further relates to a method for treatment of hydrocephalus comprising regulating drainage of CSF based on a hydrostatic pressure that is dependent on the body position of the patient.

Cerebrospinal fluid shunt for treatment of hydrocephalus

A method is described for using a postoperative CSF dynamical examination to determine the CSF dynamical state of the patient and the dynamical state of the CSF shunt in conjunction therewith.

Optimization of hydrocephalus shunt settings

The present invention relates to a method and a device for measuring the pressure p in an eye, the so-called intraocular pressure. The method includes a contact body with a known geometry being pressed against the eye with a gradually increasing contact force F and that when the area of deformation of the eye A can be determined, the pressure can be obtained from the relation P&equals;F/A, whereby the frequency characteristic of a contact body associated with a sensor system oscillating in resonance is read, the contact body is pressed against the eye to form a new system oscillating in resonance, the contact force and frequency characteristic for the new system is read, and the change in frequency characteristic is calculated. In this way, the pressure of the eye can be determined since the sought deformation area A is a function of the change A(&fnof; ch ar&excl;). The device has a contact body ( ) for pressing against the eye ( ) and a means ( ) of determining the force with which the contact body is pressed against the eye, whereby the contact body ( ) is part of a system oscillating in resonance, and the resonance system is connected to a means ( ) for reading the frequency characteristic of the system.
