Abstract

A bone graft delivery system can include an elongate tube, a handle having a trigger, and a tip. The trigger is actuated to deliver bone graft material through 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 method for delivering bone graft material to a surgical location, comprising:

providing a bone graft delivery device comprising an elongate tube;

removably coupling a distal tip to the bone graft delivery device, the distal tip having at least one opening for delivering the bone graft material to the surgical location;

positioning the device adjacent the surgical location;

decorticating bone with the distal tip; and

delivering bone graft material through the tube and out the at least one opening of the tip.

2. The method of claim 1, wherein the bone graft material comprises autogenous, cadaveric and/or synthetic material.

3. The method of claim 1, wherein the bone graft delivery device is positioned at the surgical location through a minimally invasive opening in a patient'"'"'s skin.

4. The method of claim 1, wherein the bone graft delivery device is positioned adjacent the spine and the distal tip decorticates a portion of the spine.

5. The method of claim 1, wherein decorticating bone with the distal tip comprises rasping bone with jagged edges of the distal tip.

6. The method of claim 1, wherein decorticating bone with the distal tip comprises actuating the distal tip by mechanical, battery powered, electric, pneumatic, or another means of force.

7. The method of claim 1, wherein the distal tip is generally bullet shaped.

8. The method of claim 1, wherein the distal tip is generally flat.

9. The method of claim 1, wherein the distal tip comprises at least one rasping surface configured to decorticate bone.

10. The method of claim 9, wherein the surface configured to decorticate bone extends proximally of the at least one opening.

11. The method of claim 1, wherein the distal tip is removably coupled to the distal end of the elongate tube.

12. The method of claim 1, wherein the distal tip is made of a radiopaque material.

13. The method of claim 1, wherein the distal tip comprises one or more radiopaque markers.

14. The method of claim 1, wherein the distal tip comprises a blunt end.

15. The method of claim 1, wherein the distal tip is positioned at a distal end of the elongate tube when the distal tip is removably coupled to the bone graft delivery device.

16. The method of claim 1, wherein the distal tip comprises a single monolithically formed piece.

17. The method of claim 1, wherein the distal tip is made of metal.

18. The method of claim 1, wherein the distal tip is made of a durable medical plastic.

19. The method of claim 1, wherein the distal tip is made of a composite material.

20. The method of claim 1, wherein the elongate tube is curved.
