Abstract

A bone material dispensing apparatus for preparing, mixing, and dispensing bone material into a foldable container is provided. In some embodiments, the dispensing apparatus comprises a tray and a foldable container. The tray includes a mixing surface, a dispensing surface and a means to measure the amount of material to be dispensed. A kit including a tray, a foldable container, and a spatula are also provided. A method of using the dispensing apparatus to deliver the bone material to a bone defect is also provided.

First claim

What is claimed is:

1. A bone material dispensing apparatus, comprising:
a tray having a proximal end, a distal end, a bone material dispensing surface disposed between the proximal end and the distal end of the tray and a container holding surface disposed at the proximal end of the tray adjacent to the bone material dispensing surface;
a foldable container configured to removably engage the proximal end of the tray, the foldable container being movable in a folded configuration and an unfolded configuration about a fold line in the foldable container, the foldable container having an upper compartment and a lower compartment, the lower compartment of the foldable container configured to receive a bone material from the dispensing surface of the tray when the foldable container removably engages the proximal end of the tray in the unfolded configuration and when the foldable container is in the folded configuration, the upper compartment is configured to enclose the bone material in the lower compartment, wherein the proximal end and the distal end of the tray define a longitudinal axis, and the longitudinal axis of the tray is perpendicular to a longitudinal axis of the foldable container formed by a proximal end and a distal end of the foldable container when the foldable container engages the proximal end of the tray; and wherein the container holding surface comprises a first channel and a second channel configured to hold the upper compartment and the lower compartment of the foldable container.

2. The bone material dispensing apparatus of claim 1 , wherein the first channel of the proximal end of the tray is dimensioned to correspond to the upper compartment of the foldable container and the second channel of the proximal end of the tray is dimensioned to correspond to the lower compartment of the foldable container such that at least in the unfolded configuration the foldable container is held by the tray.

3. The bone material dispensing apparatus of claim 1 , wherein the foldable container has a tubular shaped configuration and a proximal opening configured to receive a plunger and a distal opening configured to receive a cannula or fit within a cannula.

4. The bone material dispensing apparatus of claim 1 , wherein the dispensing surface comprises a mixing surface comprising a bowl configured to mix the bone material.

5. The bone material dispensing apparatus of claim 1 , wherein the dispensing surface comprises a decline extending from the distal end of the tray to the proximal end of the tray.

6. The bone material dispensing apparatus of claim 1 , wherein the dispensing surface comprises a plurality of ridges extending from the distal end to a region adjacent the proximal end, each of the plurality of ridges having a side wall and each of the plurality of ridges spaced a distance apart from each other such that a measured amount of bone material can be placed between each side wall of at least two of the plurality of ridges for measured dispensing of the bone material into the foldable container.

7. The bone material dispensing apparatus of claim 6 , the apparatus further comprising a spatula having a blade, the blade having a plurality of projections spaced a distance apart from each other, each projection configured to fit between each side wall of the plurality of ridges so as to allow measured dispensing of the bone material.

8. The bone material dispensing apparatus of claim 1 , wherein the fold line comprises a hinge that rotably connects the upper compartment and the lower compartment of the foldable container in the unfolded configuration.

9. The bone material dispensing apparatus of claim 1 , wherein the foldable container has a locking mechanism comprising a snap fit fitting, or a projection outwardly extending from an exterior of the foldable container.

10. The bone material dispensing apparatus of claim 1 , wherein the foldable container comprises a shape memory polymer.

11. The bone material dispensing apparatus of claim 1 , wherein (i) the foldable container has a tubular shape and is configured to receive a plunger at a proximal opening of the foldable container and a needle at a distal opening of the foldable container; or (ii) the foldable container is configured to be inserted into a cannula.

12. The bone material dispensing apparatus of claim 1 , wherein the proximal end of the foldable container is configured to receive a plunger, and the foldable container has an exterior having tapering extending from a region of the foldable container to the distal end of the foldable container.

13. The bone material dispensing apparatus of claim 1 , wherein the foldable container has a round, oval, rectangular, square, clover or an irregular shaped tip.
