Delivery devices and methods

A device comprising:

• a body defining a flow chamber with an inlet port for receiving a fluid flow in the flow chamber,
• an insertion port on the body for receiving a material in the flow chamber, and
• an outlet port on the body for exiting the material from the flow chamber,
• wherein the fluid flow forms a suspension of the material in the flow chamber, an amount of the material collects in the flow chamber adjacent the outlet port, and the fluid flow is operable with an interior surface of the flow chamber to push the amount of the material through the outlet port.

A device comprising:

• a body defining a flow chamber with an inlet port for receiving a fluid flow in the flow chamber;
• an outlet port on the body for exiting the material from the flow chamber;
• and
• a sheath including a proximal end attached to the outlet port, and a distal end including at least one sealed opening configured to be unsealed to exit the material.
