Abstract: A disposable set of components for an organ perfusion system comprising a fluid supply duct for supplying fluid to the organ, a fluid removal duct for removing fluid from the organ, and a surrogate organ removably connected between the fluid supply duct and the fluid removal duct so as to form a fluid circuit, so that fluid can be circulated in the circuit in preparation for connection of the organ.

Abstract: Using a known Intelligent Network Architecture a service invocation message is addressed via a Sorter to an appropriate Server. After interrogating the caller when necessary, the Server may re-address the message directly to another Server within the same organization or consortium, which may in turn repeat the process. Thereby a Service Provider representing a large business organization or consortium offers a single umbrella service and is able to introduce new services or sources of information, and to cease, re-configure or resituate the existing services with no effect whatever upon public network or message network equipment.

Abstract: A telecommunications system comprises a plurality of subscriber and/or junction terminals connected to a local exchanges the local exchange having an Intelligent Network message terminal, a Service Router addressable from the local exchange via the message terminal and a Signal Transfer Point. The local exchange is able to identify an intelligent Network service request from an originating one of the plurality of subscriber and/or junction terminals and to address and transmit a message via the message terminal to the Service Router via the Signal Transfer Point. The message is readdressed and transmitted to an appropriate Intelligent Network Service Delivery Point and upon receipt of the message by the Service Delivery Point a connection between the Service Delivery Point and the originating one of the plurality of subscriber and/or junction terminals is initiated by the Service Delivery Point.
