Abstract: A system for tracking tagged surgical articles across a network. A transport container defining an interior with upper and lower interior surfaces receives a tracking assembly including a, housing supporting an antenna arranged to selectively generate a wave extending helically away from the lower interior surface towards the upper interior surface within the interior. A communication interface wirelessly communicates with a network, and a controller coupled to the housing and disposed in electrical communication with the antenna, and the communication interface is configured to: generate the wave with the antenna to scan the interior of the transport container for tagged surgical articles, receive identity data from each of the tagged surgical articles with the antenna in response to generating the wave, and transmit the identity data, across the network via the communication interface.
