Dynamic Hardware-in-the-Loop Test Stand for Total Artificial Hearts

A new tool for the development process of total artificial hearts (TAH) dedicated for the long-term use is presented. The focus is on the modelling of a dynamic Mock Circulatory Loop, which can adapt to different physiological conditions and simulates a natural transient behaviour in between. This is important for the development of adaptive control algorithms which are able to respond to the physiological demand.After an introduction of the clinical problem, the Mock Circulatory Loop is described. The concept for the simulation process of the TAH with the Mock Circulatory Loop and with the hardware to realize Hardware-in-the-Loop (HIL) simulation is introduced. Finally, some results of the first measurements with a component of the Mock Circulatory Loop are presented.
