Delivery devices and methods
First Claim
1. A device comprising:
- a flow chamber including an inlet port for receiving a fluid flow in the flow chamber, and an outlet port for exiting a material from the flow chamber;
a formation portion of the flow chamber in which a suspension of the material is formed;
a collection portion of the flow chamber that directs the suspension toward the outlet port, wherein an amount of the material collects in the collection portion adjacent the outlet port; and
a pusher operable to move the amount of material through the outlet port, wherein the pusher is biased toward or away from the outlet port by a resilient element, wherein the pusher is configured to move between a first position outside the outlet port and a second position at least partially within the outlet port when the resilient element moves from a compressed state to an expanded state, wherein a distalmost end of the pusher is configured to contact the material to move the material toward the outlet port, wherein the pusher is longitudinally aligned with a central longitudinal axis of the outlet port.

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.

12. 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; an outlet port on the body for exiting the material from the flow chamber; and a pusher operable to move the material out of the outlet port, wherein the pusher is biased toward or away from the outlet port by a resilient element, wherein the pusher is configured to move between a first position outside the outlet port and a second position at least partially within the outlet port when the resilient element moves from a compressed state to an expanded state, wherein a distalmost end of the pusher is configured to contact the material to move the material toward the outlet port, wherein the pusher is longitudinally aligned with a direction of the fluid flow through the outlet port and configured to move through the flow chamber in the direction of the fluid flow through the outlet port; 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. - View Dependent Claims (13, 14, 15, 16, 17)

18. 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; an outlet port on the body for exiting the material from the flow chamber; a pusher operable to move the material out of the outlet port and biased toward or away from the outlet port by a resilient element, wherein the pusher is configured to move between a first position outside the outlet port and a second position at least partially within the outlet port when the resilient element moves from a compressed state to an expanded state, wherein a distalmost end of the pusher is configured to contact the material to move the material toward the outlet port; 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. - View Dependent Claims (19, 20)
