A displacement blood pump to support the natural heart of patients for recovery from end‐stage heart failure has been developed. This electromechanical pusher plate pump has a very compact and extremely flat design. The design goal was achieved by developing a novel gear system based on the principle of a swash plate. The blood pump and cannulae can be placed within the thoracic cavity between the lungs and ribcage. The first labtype model delivers an output of 3.1 L/min against an aortic pressure of 100 mm Hg at 120 bpm.
