Catheters for shunting systems for the treatment of hydrocephalus

A catheter for shunting systems for the treatment of hydrocephalus of the type comprising a tube of flexible synthetic polymer, a proximal end part of said tube adapted for insertion into a cerebral ventricle, a distal end part of said tube adapted to be inserted into a body cavity, and apertured portions in said end parts defining flow passages in their respective lateral walls for the flow of cerebro-spinal fluid from the ventricle into the tube and for the flow of said fluid from the said tube into said body cavity, wherein at least one of said end parts is constituted by a terminal element of titanium to prevent occlusive deposits of fibrin as a consequence of the ionization of said fluid by .alpha. particles present in said fluid, said terminal element being fixed at one end to said flexible tube and having at its other end lateral walls formed with said apertured portions and an internal flow duct communicating with said apertures and with the interior of said tube.
