Abstract

A bone graft delivery system can include an elongate tube and a handle having a trigger and a ratcheting mechanism. The trigger is actuated to deliver bone graft material through the tube. The bone graft delivery system can further include a distal tip at a distal end of the tube. The tip has one or more openings to deliver the bone graft material to a desired location and includes a surface suitable to act as a rasp for decorticating bone. A method for delivering bone graft material to a desired surgical location includes providing a bone graft delivery device, positioning the device adjacent the surgical location, decorticating bone, and delivering bone graft material to the surgical location.

Claims

1. A bone graft delivery system kit comprising:

a handle;

one or more elongate tubes configured to be coupled to the handle;

one or more plungers configured to be removably received in the handle and tube; and

a pusher rod configured to be removably received in the handle to urge bone graft material from the handle into the tube when one of the one or more elongate tubes is coupled to the handle.

2. The kit of claim 1, further comprising one or more tips configured to be coupled to a distal end of the one or more elongate tubes.

3. The kit of claim 2, wherein at least one of the one or more tips comprises one or more openings configured to deliver bone graft material and a surface configured to decorticate bone.

4. The kit of claim 1, further comprising a bone graft loading device, wherein the one or more elongate tubes are configured to be coupled to the bone graft loading device to be loaded with a bone graft material.

5. The kit of claim 1, wherein at least one of the one or more elongate tubes is preloaded with demineralized bone matrix.

6. The kit of claim 1, wherein at least one or the one or more elongate tubes is preloaded with a synthetic bone graft material.

7. The kit of claim 6, wherein the synthetic bone graft material comprises 40-95% calcium phosphate and 5-60% collagen.

8. The kit of claim 1, wherein at least one of the one or more elongate tubes comprises a radiopaque marker proximate a distal end of the tube.

9. The kit of claim 1, wherein at least one of the one or more elongate tubes is preloaded with an allogeneic bone graft material.

10. The kit of claim 1, wherein the one or more elongate tubes comprise:

a first elongate tube having a first length and configured to be coupled to the handle; and

a second elongate tube having a second length and configured to be coupled to the handle, wherein the second length is different from the first length;

wherein the one or more plungers are configured to be received in one or both of the first elongate tube and the second elongate tube.

11. The kit of claim 1, wherein each of the one or more elongate tubes comprises one or more markers configured to indicate a position of the tube within a body of a patient.

12. A bone graft delivery system kit comprising:

a handle;

one or more elongate tubes configured to be coupled to the handle, each elongate tube comprising a proximal end and a distal end, the proximal end comprising an externally threaded portion configured to engage an internally threaded portion of the handle;

one or more plungers configured to be removably received in the handle and tube; and

a bone graft loading device comprising;

a tube body configured to be loaded with a bone graft material, the tube body comprising a distal end comprising an internally threaded portion configured to receive and engage the externally threaded portion of the elongate tube, wherein the one or more elongate tubes are configured to be coupled to the bone graft loading device to be filled with bone graft material prior to coupling with the handle;

a plunger shaft configured to be received in the tube body; and

a plunger coupled to a distal end of the plunger shaft and configured to seal with an inner wall of the tube body.

13. The kit of claim 12, further comprising one or more tips configured to be coupled to the distal end of the one or more elongate tubes.

14. The kit of claim 13, wherein at least one of the one or more tips comprises one or more openings configured to deliver bone graft material and a surface configured to decorticate bone.

15. The kit of claim 12, further comprising a pusher rod configured to be removably received in the handle to urge bone graft material from the handle into the one or more elongate tubes when one of the one or more elongate tubes is coupled to the handle.

16. The kit of claim 12, wherein the bone graft loading device comprises:

a cap disposed on the plunger shaft and configured to removably couple to a proximal end of the tube body, wherein the cap comprises an internally threaded through-hole configured to receive the plunger shaft, wherein the plunger shaft is externally threaded.

17. The kit of claim 12, wherein at least one of the one or more elongate tubes is preloaded with demineralized bone matrix.

18. The kit of claim 12, wherein at least one or the one or more elongate tubes is preloaded with a synthetic bone graft material.

19. The kit of claim 18, wherein the synthetic bone graft material comprises 40-95% calcium phosphate and 5-60% collagen.

20. The kit of claim 12, wherein at least one of the one or more elongate tubes comprises a radiopaque marker proximate the distal end of the tube.

21. The kit of claim 12, wherein at least one of the one or more elongate tubes is preloaded with an allogeneic bone graft material.

22. The kit of claim 12, wherein the one or more elongate tubes comprise:

a first elongate tube having a first length and configured to be coupled to the handle; and

a second elongate tube having a second length and configured to be coupled to the handle, wherein the second length is different from the first length;

wherein the one or more plungers are configured to be received in one or both of the first elongate tube and the second elongate tube.

23. The kit of claim 12, wherein each of the one or more elongate tubes comprises one or more markers configured to indicate a position of the tube within a body of a patient.

24. The kit of claim 15, wherein each of the one or more elongate tubes comprises one or more markers configured to indicate a position of the tube within a body of a patient, wherein the one or more elongate tubes comprise:

a first elongate tube having a first length and configured to be coupled to the handle; and

a second elongate tube having a second length and configured to be coupled to the handle, wherein the second length is different from the first length;

wherein the one or more plungers are configured to be received in one or both of the first elongate tube and the second elongate tube.

25. The kit of claim 24, wherein each of the first elongate tube and the second elongate tube are sufficiently rigid to maintain a permanent shape during positioning of the first elongate tube or the second elongate tube within the body of the patient.
