Abstract

This invention generally relates to devices and methods for repairing an aperture in biological tissue. In certain embodiments the invention provides as system for closing an aperture in a biological tissue including a handle, an elongate shaft connected to the handle, a deployment scaffold connected to the shaft, in which the scaffold is configured to releasably retain a surgical implant, and at least one adhesive dispensing system.

Claims

1. A system for closing an aperture in a biological tissue, the system comprising:

a handle;

an elongate shaft connected to the handle;

a deployment scaffold connected to the shaft, the deployment scaffold including;

first and second frame arms, wherein the deployment scaffold is configured to releasably retain a surgical implant; and

proximal deployment arms and distal deployment arms hingedly connected to the first and second frame arms, wherein the deployment scaffold is configured to move from a retained position to a deployed position; and

at least one adhesive dispensing system, the at least one adhesive dispensing system having at least one dispensing tube external to the deployment scaffold, the at least one dispensing tube extending along an outer surface of the first and second frame arms.

2. The system according to claim 1, wherein the adhesive dispensing system further comprises:

at least one reservoir for holding adhesive;

the at least one dispensing tube connected to the at least one reservoir; and

at least one nozzle connected to the at least one dispensing tube.

3. The system according to claim 2, wherein the at least one reservoir is removable from the adhesive dispensing system.

4. The system according to claim 2, wherein the at least one reservoir comprises a breakable membrane.

5. The system according to claim 2, wherein the at least one nozzle is integrated with the deployment scaffold and the at least one nozzle is configured to dispense adhesive from a lower surface of the surgical implant releasably retained by the deployment scaffold.

6. The system according to claim 2, further including:

at least two reservoirs, wherein each reservoir holds a different type of adhesive; and

at least two dispensing tubes, each dispensing tube fluidly coupled to one of the reservoirs.

7. The system according to claim 2, further including:

at least two reservoirs, wherein each reservoir holds a different component of a multi-component adhesive; and

at least two dispensing tubes, each dispensing tube fluidly coupled to one of the reservoirs.

8. The system according to claim 2, wherein the nozzles are positioned such that they dispense adhesive in a common direction.

9. The system according to claim 1, wherein the dispensing system is configured to dispense adhesive onto the surgical implant while it is releasably retained by the deployment scaffold.

10. The system according to claim 1, wherein the system further comprises a biocompatible adhesive held within the adhesive dispensing system.

11. The system according to claim 10, wherein the adhesive is glue.

12. The system according to claim 11, wherein the glue is fibrin sealant or cyanoacrylate.

13. The system according to claim 1, wherein the deployment scaffold comprises a plurality of arms that are configured to move from a retained position to a plurality of deployed positions, wherein the arms hold the surgical implant.

14. The system according to claim 1, wherein the deployment scaffold is configured to allow for deployment of the surgical implant and retraction of the surgical implant while the surgical implant is within a patient'"'"'s body.

15. The system according to claim 1, wherein the deployment scaffold is configured to allow for a plurality of deployment positions.

16. The system according to claim 1, wherein the deployment scaffold comprises an articulating member that allows for adjustment of the position and the orientation of the surgical implant relative to an aperture in tissue.

17. The system according to claim 1, further comprising a surgical implant.

18. The system according to claim 17, wherein the surgical implant is a patch.

19. The system according to claim 18, wherein the patch is porous.

20. The system according to claim 18, wherein the patch is comprised of surgical mesh.

21. The system according to claim 18, wherein the patch is non-porous.

22. The system according to claim 1, wherein the system is adapted for closing an aperture in an abdominal wall.

23. The system according to claim 1, wherein the elongate shaft is flexible.

24. The system according to claim 1, wherein the elongate shaft is rigid.

25. The system according to claim 1, wherein the first and second frame arms include connection clips connected to the first and second frame arms and configured to releasably hold the surgical implant.

26. The system according to claim 25, wherein the deployment scaffold further includes a central frame piece that is slidably connected to the elongate shaft and hingedly connected to the distal deployment arms, wherein the central frame piece slides from a distal position wherein the deployment scaffold is retracted to a proximal position wherein the deployment scaffold is deployed.

27. The system according to claim 1, wherein the system is configured such that the adhesive dispensing system dispenses adhesive onto the biological tissue prior to the surgical implant being attached to the biological tissue.
