Abstract: A venous catheter comprising a flexible and resilient tube of synthetic polymer, provided with a tubular tip made of titanium alloy, which confers to the end of the catheter both inherent antithrombogenic properties and a mass such as to substantially prevent the excitation of oscillations of the catheter caused by the pulsations of the venous flow and the cardiac muscle contractions. The catheter is suitable for intravenous extended perfusions and for use in peritoneo-venous shunting systems in the treatment of ascites.

Abstract: A shunting system for the treatment of hydrocephalus comprises a proximal catheter and/or a distal catheter in which a proximal and/or a distal end part of a tube of silicone rubber or other synthetic flexible polymer is constituted by a tip of titanium fixed to a corresponding end of the tube and affording an internal flow passage communicating at one end with flow apertures formed in the lateral walls of the tip and at the other end with the interior of the tube.
