Abstract

A device for hydrating particulate bone material is provided. The device comprises a tubular member having an interior surface and an exterior surface. The interior surface is configured to receive the particulate bone material and a hydration fluid. The exterior surface has a plurality of pores configured to allow the hydration fluid to flow into the interior surface of the tubular member and hydrate the particulate bone material. The plurality of pores are smaller in size than the particulate bone material. Methods of dispensing particulate the bone material are also provided.

First claim

What is claimed is:

1. A device for hydrating particulate bone material, the device comprising a tubular member having an interior surface and an exterior surface, the interior surface configured to receive the particulate bone material and a hydration fluid, the exterior surface having a plurality of pores configured to allow the hydration fluid to flow into the interior surface of the tubular member and hydrate the particulate bone material, the plurality of pores being smaller in size than the particulate bone material, wherein the tubular member comprises a proximal end opening configured to receive the particulate bone material and the tubular member is configured to slidably engage a cannula and the proximal end opening of the tubular member is configured to slidably receive a plunger, and the proximal end opening of the tubular member comprises a rigid funnel configured to engage the cannula, or a proximal end of the cannula comprises a collar configured to engage the tubular member.

2. The device of claim 1 , wherein the tubular member comprises a distal end opening configured to dispense the particulate bone material.

3. The device of claim 1 , wherein the tubular member comprises a removable distal end configured to form a distal end opening to dispense the particulate bone material.

4. The device of claim 1 , wherein the tubular member comprises a mesh or a straw.

5. The device of claim 1 , wherein the tubular member is moldable or flexible.

6. The device of claim 1 , wherein the plurality of pores have a pore size from about 10 to about 100 microns.

7. The device of claim 1 , wherein the tubular member comprises a one-way valve.

8. The device of claim 7 , wherein the tubular member comprises a port configured to receive a syringe.

9. The device of claim 8 , wherein the port is disposed perpendicular to the tubular member.

10. The device of claim 7 , wherein the interior surface of the tubular member at a proximal end comprises threading to engage with a threaded outer surface of a plunger.

11. The device of claim 1 , wherein (i) the particulate bone material is in a powder or a wet form; (ii) the particulate bone material has a particle size of 250 microns or less; or (iii) the particulate bone material is demineralized bone (DBM).

12. A device for hydrating particulate bone material, the device comprising a tubular member having an interior surface configured to receive the particulate bone material and a hydration fluid, the tubular member having a proximal end opening configured to receive a syringe, and a distal end opening configured to receive a cap, the cap having a plurality of pores configured to allow the hydration fluid to flow into the interior surface of the tubular member and hydrate the particulate bone material, the plurality of pores being smaller in size than the particulate bone material, wherein the tubular member is configured to slidably engage a cannula and the proximal end opening of the tubular member comprises a rigid funnel configured to engage the cannula, or a proximal end of the cannula comprises a rigid funnel configured to engage the tubular member.

13. The device of claim 12 , wherein the proximal end opening engages with a cap comprising a luer fitting that engages with the syringe.

14. The device of claim 12 , wherein (i) the particulate bone material is in a powder or a wet form; (ii) the particulate bone material has a particle size of 250 microns or less; or (iii) the particulate bone material is demineralized bone (DBM).

15. A method of dispensing particulate bone material at a surgical site, the method comprising loading a device for hydrating the particulate bone material, the device comprising a tubular member having an interior surface and an exterior surface, the interior surface configured to receive the particulate bone material and a hydration fluid, the exterior surface having a plurality of pores configured to allow the hydration fluid to flow into the interior surface of the tubular member and hydrate the particulate bone material, the plurality of pores being smaller in size than the particulate bone material; immersing the device in a fluid filled bath; and engaging the device with a cannula and a plunger to dispense the particulate bone material to the surgical site.

16. The method of claim 15 , wherein a proximal end opening of the tubular member comprises a collar configured to engage the cannula, or a proximal end of the cannula comprises a collar configured to engage the tubular member.

17. The method of claim 15 , wherein the tubular member comprises a removable distal end configured to form a distal end opening to dispense the particulate bone material.
