Abstract: A device for delivering an agent may comprise a chamber for receiving agent through an agent inlet; and a body received within the chamber. The body may be movable in first and second directions along a longitudinal axis of the chamber. In a first configuration of the body, an amount of the agent may flow into the chamber via the agent inlet. In a second configuration of the body, the agent is prevented from flowing into the chamber via the agent inlet. When the body is transitioned from the first configuration to the second configuration, the amount of the agent may be moved from a first position along the longitudinal axis of the chamber to a second position along the longitudinal axis of the chamber.
