A device and method for providing a suspended agent such as a contrast agent without mechanical resuspension. A volume of agent is divided into sub-volumes in a network of tubes, cells, sponges, grooves, etc. A propellant fluid flows through the network to release the suspended agent. The network may be internal to a container for the propellant fluid. Alternatively, the network may be adjacent an exit port of a container for the propellant fluid, or may be in-line between a propellant fluid container and a patient. The invention reduces sedimentation of agents into one or a few aggregates and eliminates a mechanical mixing step. The invention thus provides a uniformly suspended agent, improving patient health and safety and increasing cost and time savings.
