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.

First claim

1 - 20 . (canceled)

21 . A device comprising:
an inlet port for receiving a fluid flow; an outlet port in communication with the inlet port; a collection portion between the inlet port and the outlet port; and a pusher configured for insertion into the collection portion and operable to move an amount of material from the collection portion towards the outlet port, wherein:
the pusher is biased toward or away from the outlet port by a resilient element,
the pusher is configured to move between a first position proximal to the outlet port and a second position at least partially distal to the outlet port when the resilient element moves from a compressed state to an expanded state,
the pusher is configured to move towards the outlet port along a direction of the fluid flow when the resilient element moves from the compressed state to the expanded state, and
a portion of the pusher is configured to contact the amount of material to move the amount of material towards the outlet port.

22 . The device of claim 21 , wherein a central longitudinal axis of the pusher is parallel to a central longitudinal axis of the outlet port.

23 . The device of claim 21 , further comprising a formation portion in communication with the collection portion, wherein the formation portion includes a semi-spherical surface defining a volume for receiving the fluid flow.

24 . The device of claim 23 , wherein the formation portion includes a semi-frustoconical surface configured to funnel the fluid flow towards the collection portion.

25 . The device of claim 21 , further comprising a stopper movable between a first position to compress the resilient element into the compressed state, and a second position to release the resilient element into the expanded state.

26 . The device of claim 21 , further comprising a sheath coupled to, and extending distally from, the outlet port, wherein the pusher is operable to push the amount of material into the sheath, and wherein a distal end of the sheath includes at least one opening configured to distribute the amount of material.

27 . The device of claim 26 , wherein the at least one opening of the distal end of the sheath is moveable between an open position and a closed position.

28 . The device of claim 26 , further comprising a removable plug or cap for the at least one opening of the distal end of the sheath.

29 . The device of claim 26 , wherein at least the distal end of the sheath includes a hydrophilic coating.

30 . The device of claim 21 , further comprising a body defining the flow chamber and configured to receive the pusher; wherein the pusher includes a stopper portion protruding from a radially outer surface of pusher, wherein the body includes an offshoot configured to allow the stopper portion to pass through the offshoot, wherein alignment of the stopper portion and the offshoot is configured to cause the resilient member to move from the compressed state to the expanded state.

31 . A device comprising:
a flow chamber; a first inlet port in communication with the flow chamber and defining a first flow path for receiving a fluid; a second inlet port in communication with the flow chamber and defining a second flow path for receiving a material; an outlet port in communication with the flow chamber; and a pusher operable to move the material in a proximal to distal direction towards the outlet port, wherein:
the pusher is biased toward or away from the outlet port by a resilient element,
the pusher is configured to move between a first position proximal to the second inlet port and a second position distal to the second inlet port when the resilient element moves from a compressed state to an expanded state,
the pusher is configured to contact the material to move the material toward the outlet port, and
the pusher is longitudinally aligned with the first flow path and configured to move along the first flow path through the outlet port.

32 . The device of claim 31 , wherein the first flow path and the second flow path intersect to allow the fluid and the material to combine in the flow chamber, and wherein an interior surface of the flow chamber includes surface features to facilitate passage of the material from the flow chamber towards the outlet port.

33 . The device of claim 31 , further comprising a handle portion.

34 . The device of claim 31 , further comprising a sheath extending distally from the outlet port, wherein a distal end of the sheath includes at least one opening configured to distribute an amount of material.

35 . The device of claim 34 , wherein the at least one opening of the distal end of the sheath is moveable between an open position and a closed position.

36 . The device of claim 31 , wherein the pusher is configured to move the material within the fluid.

37 . A device comprising:
a flow chamber; a first inlet port defining a first flow path for receiving a fluid flow; a second inlet port defining a second flow path for receiving a material; an outlet port in communication with each of the flow chamber, the first inlet port, and the second inlet port; a pusher operable to move the material towards 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 and a second position when the resilient element moves from a compressed state to an expanded state, wherein a distal most end of the pusher is closer to the outlet port when the resilient element in the expanded state than when the resilient element is in the compressed state; and a sheath including a proximal end and a distal end, the proximal end being coupled to the outlet port.

38 . The device of claim 37 , wherein the first flow path and the second flow path intersect to allow the fluid and the material to combine in the flow chamber.

39 . The device of claim 37 , wherein an interior surface of the flow chamber is configured to cause turbulent fluid flow or a vortex.

40 . The device of claim 37 , further comprising a body defining the flow chamber and configured to receive the pusher; wherein an outer surface of the pusher includes a stopper portion protruding from a radially outer surface of the pusher, wherein the body includes an offshoot configured to allow the stopper portion to pass through the offshoot, wherein alignment of the stopper portion and the offshoot is configured to cause the resilient member to move from the compressed state to the expanded state.
