Abstract: Implementations of a delivery device and method are disclosed. One implementation is a delivery device comprising a flow chamber with an inlet port for receiving a fluid flow in the flow chamber, and an outlet port for exiting a material from the flow chamber. The flow chamber may include a formation portion in which a suspension of the material is formed, and a collection portion that directs the suspension toward and/or into the outlet port. An amount of the material may collect in the collection portion adjacent the outlet port. The device may further comprise an insertion port for permitting insertion of the material in the flow chamber, and/or a pusher operable to move the amount of material through the outlet port. Related devices and methods also are disclosed.
