Abstract
A catheter system that can be used for concurrent fluid infusion and aspiration in humans, animals and biological material, at a wide range of flow rates, without any blockage problems. The system has devices that control the infused liquid's pressure changes accordingly to the aspirated liquid's pressure changes, in order to allow accurate and safe fluid exchange flow control and create changes of pressures at the catheter's tip that do not allow the catheter's blockage.
