Abstract

A device and method for dispensing an adhesive wherein a housing includes a proximal portion and distal portion, an opening is defined in the distal portion of the housing, and a housing lumen is defined within the housing and extends through the opening. The device may also include a syringe including a body defining a syringe lumen and a delivery tip, wherein at least a portion of the body is positionable within the housing lumen. Furthermore, a screw including a proximal end and a distal end and a plunger are positionable within the syringe lumen.

Claims

1. A delivery device comprising:

a housing including a proximal portion and distal portion;

an opening defined in said distal portion of said housing;

a housing lumen defined within said housing and extending through said opening;

a syringe including a body defining a syringe lumen and a delivery tip, wherein a portion of said body is positionable within said housing lumen;

a screw including a proximal end and a distal end positionable within said syringe lumen, wherein said proximal end of said screw includes a head configured to be engaged with a driving device; and

a plunger positionable within said syringe lumen.

2. The delivery device of claim 1, wherein said proximal portion of said housing defines a handle.

3. The delivery device of claim 1, further comprising a bore defined in said housing, wherein said syringe includes an ear portion that mates with said bore.

4. The delivery device of claim 1, wherein said syringe is retained in said housing in a non-rotate-able manner relative to said housing.

5. The delivery device of claim 1, further comprising an end cap mate-able with said housing.

6. The delivery device of claim 5, wherein said end cap further comprises an orifice for receiving said screw.

7. The delivery device of claim 5, wherein said housing includes a first locking feature and said end cap includes a second locking feature, wherein said first and second locking features are configured to mate.

8. The delivery device of claim 1, wherein said screw includes a stop collar.

9. The delivery device of claim 1, wherein said driving device is selected from the group consisting of a screw driver or a drill.

10. The delivery device of claim 1, wherein said plunger is positionable within said syringe lumen in a non-rotating manner.

11. The delivery device of claim 1, wherein said distal end of said screw includes an abutment to mate with said plunger.

12. The delivery device of claim 1, wherein said delivery tip is positioned outside of said housing.

13. The delivery device of claim 1, wherein said syringe lumen includes an adhesive having a viscosity in the range of about 1,000 cP to 100,000,000 cP, wherein said viscosity is measured at a temperature of 25°

14. A method of dispensing an adhesive comprising:

placing at least a portion of a syringe including a syringe lumen and a delivery tip in a housing;

inserting a plunger into said syringe lumen;

positioning a screw within said syringe lumen;

advancing said screw in said syringe lumen via a driving device; and

advancing said plunger in said syringe lumen.

15. The method of claim 14, further comprising filling said syringe lumen with adhesive.

16. The method of claim 14, wherein said syringe includes an ear and said housing includes a bore to receive said ear and mating said ear in said bore.

17. The method of claim 14, wherein said screw includes a stop collar and said plunger is advanced until said stop collar abuts said housing.

18. The method of claim 14, further comprising retaining said syringe within said housing in a non-rotatable manner.

19. The method of claim 14, further comprising mating an end cap to the housing to retain said syringe within said housing.

20. The method of claim 14, wherein said screw mates with said plunger.

21. The method of claim 14, wherein said plunger is advanced in a non-rotating manner with respect to said syringe.

22. The method of claim 14, wherein said syringe lumen includes an adhesive having a viscosity in the range of about 1,000 cP to 100,000,000 cP, wherein said viscosity is measured at a temperature of 25°
