Patients with severe forms of respiratory failure frequently require mechanical ventilation and membrane oxygenation therapy to support  their  lung function. An intravenous membrane oxygenator, consisting of a hollow  fiber membrane packing and a drive unit, is proposed as a minimal invasive respiratory assist device.The usage of a blood pump deals with major challenges in  the design of an intravenous device, specifically overcoming the pressure drop caused by the membrane packing and enabling a controllable blood  flow. Apart  from  the complex design, pump production for experimental investigation poses a difficulty due to the small size of the individual pump parts.In this study, we demonstrate the rapid prototyping process of a micro mixed flow catheter pump using different lithographic based approaches. Pump characteristic experiments were  conducted, showing the functionality of the manufactured parts.
