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; and

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

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

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 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.

5. 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.

6. The kit of claim 5, wherein the bone graft loading device comprises:

a tube body configured to be loaded with a bone graft material;

an externally threaded plunger shaft configured to be received in the tube body;

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

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 externally threaded plunger shaft.

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

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

9. The kit of claim 8, wherein the synthetic bone graft material comprises 40-95% calcium phosphate and 5-60% collagen.

10. 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.

11. An interbody implant comprising:

a leading end, a trailing end, and first and second sidewalls extending between the leading end and trailing end;

a central opening bounded by the leading end, trailing end, and first and second sidewalls;

wherein the trailing end comprises a hole, a perimeter of the hole having engagement features configured to mate with corresponding engagement features on a distal end of a tube of a bone graft delivery device, and the hole in fluid communication with the central opening;

wherein at least one of the first and second sidewalls comprises at least one hole in fluid communication with the central opening, and wherein a perimeter of the at least one hole is tapered outwardly from an inner surface to an outer surface of the at least one of the first and second sidewalls.

12. The interbody implant of claim 11, wherein the engagement features of the implant comprise alternating ridges and recesses and the corresponding engagement features of the distal end of the tube comprise corresponding recesses and ridges.

13. The interbody implant of claim 11, wherein the implant is expandable.

14. The interbody implant of claim 11, wherein each of the first and second sidewalls comprises three holes.

15. The interbody implant of claim 11, wherein the first and second sidewalls comprise upper bone contacting surfaces configured to contact a superior vertebral body and lower bone contacting surfaces configured to contact an interior vertebral body.

16. The interbody implant of claim 11, wherein the leading end is tapered.
