To translate recent advances in medical device interoperability research into clinical practice, standards are being developed that specify precise requirements towards the network representation of particular medical devices connecting through ISO/IEEE 11073 SDC. The present contribution supplements this protocol standard with specific models for endoscopic camera systems, light sources, insufflators, and pumps. Through industry consensus, these new standards provide modular means to describe the devices' capabilities and modes of interaction in a service-oriented medical device communication architecture. This enables seamless data exchange and the potential for new assistive systems to support the caregiver.
