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 bone graft delivery system, comprising:

an elongate tube;

a handle at a proximal end of the tube configured to be actuated to deliver bone graft material through the tube; and

a tip at a distal end of the tube, the tip having one or more openings configured to deliver the bone graft material to a desired location, wherein the one or more openings are positioned transverse to a longitudinal axis of the tube and wherein the tip includes a surface configured to decorticate bone, the surface configured to decorticate bone extending proximally of the one or more openings.

2. The system of claim 1, wherein the surface of the tip includes jagged edges.

3. The system of claim 1, wherein the tip is made of metal.

4. The system of claim 1, wherein the tip is made of a radiopaque material.

5. The system of claim 1, wherein the tip is made of a durable medical plastic.

6. The system of claim 1, wherein the tip is made of a composite material.

7. The system of claim 5, wherein the tip includes one or more radiopaque markers.

8. The system of claim 6, wherein the tip includes one or more radiopaque markers.

9. The system of claim 1, wherein the tip has a blunt end.

10. The system of claim 1, wherein the elongate tube is rigid.

11. The system of claim 1, wherein the elongate tube includes a permanent bend.

12. The system of claim 1, wherein the handle comprises a trigger configured to be actuated to deliver a controlled release amount of bone graft material through the tube per actuation.

19. The system of claim 1, wherein the surface configured to decorticate bone is positioned on one side of the tip.

13. A method for delivering bone graft material to a surgical location, comprising:

providing a bone graft delivery device comprising an elongate tube, a handle at a proximal end of the tube, and a distal tip having a rasping surface and 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 rasping surface of the distal tip; and

with the rasping surface at the distal tip of the bone graft delivery device, delivering bone graft material through the tube and out the at least one opening of the tip, wherein delivering the bone graft material comprises actuating the handle to deliver a controlled release amount of bone graft material per actuation.

14. The method of claim 13, wherein the bone graft material comprises autogenous, cadaveric and/or synthetic material.

15. The method of claim 13, wherein the bone graft delivery device is positioned at the surgical location through a minimally invasive opening in a patient'"'"'s skin.

16. The method of claim 13, wherein the bone graft delivery device is positioned adjacent the spine and the distal tip decorticates a portion of the spine.

17. The method of claim 13, wherein decorticating bone with the distal tip comprises rasping bone with jagged edges of the distal tip.

18. The method of claim 13, wherein decorticating bone with the distal tip comprises actuating the distal tip by mechanical, battery powered, electric, pneumatic, or another means of force.

20. A bone graft delivery system, comprising:

an elongate tube;

a handle at a proximal end of the tube configured to be actuated to deliver bone graft material through the tube, wherein the handle comprises a trigger configured to be actuated to deliver a controlled release amount of bone graft material per actuation; and

a tip at a distal end of the tube, the tip having a rasping surface and one or more openings configured to deliver the bone graft material to a desired location, wherein the openings are configured to deliver the bone graft material to the desired location with the rasping surface at the distal end of the tube.
