Abstract

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

Claims

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

a handle;

a telescopic shaft connected to the handle; and

a deployment scaffold connected to the shaft, wherein the scaffold is configured to releasably retain a surgical implant and the scaffold is configured to deploy and attach the surgical implant to the biological tissue.

2. The system according to claim 1, wherein the scaffold comprises:

a plurality of arms that are configured to move from a retained position to at least one deployed position; and

a plurality of attachment members that are releasably connected to the arms, wherein the attachment members attach the surgical implant to the biological tissue.

3. The system according to claim 2, wherein the arms are flexible.

4. The system according to claim 2, wherein the arms are rigid.

5. The system according to claim 2, wherein the number of attachment members is independent of the number of arms.

6. The system according to claim 2, wherein the attachment members are selected from the group consisting of clips, hooks, and barbs.

7. The system according to claim 2, wherein in attachment is obtained by rotational or linear movement of the attachment members.

8. The system according to claim 1, wherein the scaffold comprises:

a frame;

a plurality of deployment arms hingedly connected to the frame, wherein the frame is configured to move from a retained position to at least one deployed position; and

a plurality of attachment members that are releasably connected to the scaffold, wherein the attachment members attach the surgical implant to the biological tissue.

9. The system according to claim 8, wherein the deployment arms releasably connect to the central shaft when the scaffold is in a closed configuration.

10. The system according to claim 9, wherein the deployment arms are released from the central shaft by movement of the shaft from a closed configuration to an open configuration.

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

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

13. 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 the aperture in the tissue.

14. The system according to claim 13, wherein the articulating member allows for vertical flexibility of the deployment scaffold in order to press the implant against the tissue.

15. The system according to claim 1, further comprising the surgical implant.

16. The system according to claim 15, wherein the implant is connected to the system in an operating room.

17. The system according to claim 15, wherein the surgical implant is a patch.

18. The system according to claim 17, wherein the patch is comprised of surgical mesh.

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

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

21. The system according to claim 1, wherein the aperture in the biological tissue is an aperture in an abdominal wall.

22. The system according to claim 1, wherein deployment is accomplished by liner movement of the shaft with respect to the handle.

23. The system according to claim 1, wherein the telescopic shaft comprises:

a hollow member have a rod that is configured to extend from and retract into the member.

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

a handle;

a telescopic shaft connected to the handle; and

a deployment scaffold connected to the shaft, wherein the scaffold is configured to releasably retain a surgical implant and the scaffold is configured to allow for lateral deployment of the implant with respect to the shaft and retraction of the implant while the implant is within a patient'"'"'s body.

25. The system according to claim 24, further comprising the surgical implant.

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

a handle;

a telescopic shaft connected to the handle; and

a deployment scaffold connected to the shaft, wherein the scaffold is configured to releasably retain a surgical implant and the scaffold is configured to allow for a plurality of deployment positions.

27. The system according to claim 26, further comprising the surgical implant.

28. The system according to claim 27, wherein the system is configured for active deployment of the implant.

29. A method for closing an aperture in a biological tissue, the method comprising;

inserting into a surgical site of a patient an instrument having a telescopic shaft and a deployment scaffold connected to the shaft, wherein the deployment scaffold is configured to releasably retain a surgical implant;

deploying the surgical implant;

using the deployment scaffold to attach the implant to the biological tissue, thereby covering the aperture in the tissue; and

releasing the implant from the instrument.

30. The method according to claim 29, wherein prior to the using step, the method further comprises adjusting the position and the orientation of the implant relative to the aperture in the tissue.

31. The method according to claim 29, wherein the aperture in the biological tissue is an aperture in an abdominal wall.

32. The method according to claim 29, wherein deploying is accomplished in a controlled and continuous manner.

33. The method according to claim 29, wherein prior to the using step, the method further comprises:

assessing the deployment of the implant relative to the aperture in the tissue;

retracting the implant; and

re-deploying the implant.

34. The method according to claim 29, wherein the using and the releasing steps are performed sequentially.

35. The method according to claim 29, wherein the using and the releasing steps are performed simultaneously.
