Abstract: Leveraging connectivity and interoperability of medical devices promises a great benefit for patient safety and effectiveness of medical services. However, safety issues arising from coordination failures between networked medical devices pose a significant challenge to achieve such vision. In this paper, we propose an organ-based semi-autonomous hierarchical control structure as an architectural design principle to make integrated medical systems more resilient and effective against communication failures. The proposed design principle also enables the development of tools supporting rapid hierarchical composition of organ-based clusters and the verification of safety assertions. Our simulation study shows that our approach can provide the safety while minimally interrupting ongoing medical services in the face of network failures.
