Abstract: A medical system includes a propellant source containing a propellant fluid, containers containing a material, and a shaft having a plurality of lumens, each of the plurality of lumens having a first opening at a proximal end of the shaft and a second opening at a distal end of the shaft. The plurality of lumens are fluidly coupled to one or more of the propellant source and at least one of the plurality of containers, and a first lumen surrounds, is coaxial with, or is side-by-side with, at least one other lumen.

Abstract: An apparatus for delivering a powdered agent into a subject's body may include a first passage for receiving a pressurized gas. The apparatus also may include a container housing a powdered agent. The container may be in fluid connection with the first passage. At least a portion of the pressurized gas is introduced into the powdered agent in the container to fluidize the powdered agent. The apparatus also may include a second passage for receiving the powdered agent from the container. In a first configuration of the apparatus, the second passage may not be in fluid connection with the container. In a second configuration of the apparatus, the second passage may be in fluid connection with the container. The apparatus may be configured to transition between the first configuration and the second configuration.
