    We are currently developing a total artificial heart which can be defined as a mechatronic system. Reliability demonstration of such systems requires, especially for medical systems, long-term durability tests on a large number of entities for reaching a high confidence level. This classical system-based approach could be clearly improved by decomposing the system into subsystems, introducing expert knowledge, studying functionnal system architecture and collecting new reliability-related component information. Finally, we propose to design an overall reliability demonstration methodology for the optimization of a test plan at the system level based on an « a priori » system reliability evaluated on the respective reliability performance of all of the components.
