Abstract

A device for delivering an allograft patch through a cannula provides for feeding of the device and the allograft patch through the cannula and provides for deploying of the allograft patch after feeding through the cannula.

Claims

1. A device for delivering an allograft patch through a cannula, comprising:

a central pad portion;

an inflatable chamber portion provided around a perimeter of the central pad portion; and

a fluid influx tube extended from and communicated with an interior of the inflatable chamber portion,

wherein the fluid influx tube has an open end to provide for selective inflation of the inflatable chamber portion.

2. The device of claim 1, wherein the central pad portion is configured to support the allograft patch such that a superior surface of the allograft patch is configured to be adjacent a surface of the central pad portion.

3. The device of claim 1, wherein the central pad portion has a rectangular shape with four sides, and wherein the inflatable chamber portion is provided along the four sides of the rectangular shape.

4. The device of claim 3, wherein the fluid influx tube extends from one of the four sides of the rectangular shape.

5. The device of claim 1, wherein the central pad portion has a longitudinal axis, and wherein the fluid influx tube extends along the longitudinal axis.

6. The device of claim 1, wherein the device and the allograft patch are configured to be rolled up around a longitudinal axis to feed the device and the allograft patch through the cannula.

7. The device of claim 1, wherein the inflatable chamber portion is configured to be deflated to feed the device and the allograft patch through the cannula.

8. The device of claim 1, wherein the inflatable chamber portion is configured to be inflated via the fluid influx tube to deploy the allograft patch.

9. The device of claim 1, wherein the fluid influx tube is configured to be removed.

10. The device of claim 1, wherein the central pad portion and the inflatable chamber portion are formed of a bioabsorbable material.

11. A device for delivering an allograft patch through a cannula, comprising:

one or more stiffening strips providing along one or more sides of the allograft patch.

12. The device of claim 11, wherein the one or more stiffening strips include two stiffening strips provided along two opposite sides of the allograft patch.

13. The device of claim 12, wherein the one or more stiffening strips further include a third stiffening strip provided along a third side of the allograft patch.

14. The device of claim 11, wherein the device and the allograft patch are configured to be rolled up around a longitudinal axis to feed the device and the allograft patch through the cannula.

15. The device of claim 14, wherein the stiffening strips extend substantially parallel with the longitudinal axis.

16. The device of claim 11, wherein the stiffening strips are formed of a bioabsorbable material.

17. A device for delivering an allograft patch through a cannula, comprising:

means for providing rigidity to the allograft patch and accommodating rolling of the device and the allograft patch around a longitudinal axis for feeding of the device and the allograft patch through the cannula and deploying of the allograft patch after feeding through the cannula.

18. The device of claim 17, wherein the means comprises a central pad portion and an inflatable chamber portion provided around a perimeter of the central pad portion, wherein the central pad portion is configured to support the allograft patch.

19. The device of claim 17, wherein the means comprises one or more stiffening strips provided along one or more sides of the allograft patch.

20. The device of claim 17, wherein the means is formed of a bioabsorbable material.
