Abstract

The invention generally relates to devices and methods for repairing an aperture in biological tissue. In certain embodiments, the invention provides devices and methods for deploying an implant to interact with biological tissue during a surgery.

Claims

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

a handle;

an elongate shaft connected to the handle, wherein the shaft is rigid during insertion of the system into a subject and flexible during attachment of a surgical implant to a biological tissue; and

a deployment scaffold connected to the shaft, wherein the scaffold is configured to deploy the surgical implant.

2. The system according to claim 1, wherein the scaffold releasably retains the implant.

3. The system according to claim 1, wherein the scaffold attaches the implant to the biological tissue.

4. The system according to claim 1, wherein the elongate shaft comprises:

first and second rigid portions connected by a flexible portion, wherein the first and second rigid portions are interlocked to provide rigidity to the shaft.

5. 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, wherein one or more of the arms hold the implant.

6. The system according to claim 5, wherein the arms are flexible.

7. The system according to claim 5, wherein the arms are rigid.

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 plurality of deployment arms are configured to move from a retained position to a plurality of deployed positions;

wherein the frame holds the implant.

9. 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.

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

11. 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.

12. The system according to claim 11, wherein the articulating member comprises wires that control the adjustment of the surgical implant.

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

14. The system according to claim 13, wherein the surgical implant is a patch.

15. The system according to claim 14, wherein the patch is porous.

16. The system according to claim 14, wherein the patch is non-porous.

17. The system according to claim 14, wherein the patch is comprised of surgical mesh.

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

23. The method according to claim 12, wherein prior to the transforming step or the attaching step, the method further comprises adjusting the position and the orientation of the implant relative to the aperture in the tissue.

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

a handle;

an elongate shaft connected to the handle; and

a deployment scaffold connected to the shaft, wherein the scaffold is configured to deploy the surgical implant and the scaffold is configured to slide along the elongate shaft.

20. The system according to claim 19, 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.

21. The system according to claim 20, wherein in the deployed position, hinges of the scaffold combine together, allowing for lateral articulation of the deployment scaffold.

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

inserting an instrument having a rigid hollow elongate shaft into a surgical site of a patient;

deploying a surgical implant from the elongate shaft;

transforming the rigid shaft to a flexible shaft;

attaching the implant to the biological tissue, thereby covering the aperture in the tissue; and

disconnecting the implant from the instrument.

24. The method according to claim 22, wherein the aperture in the biological tissue is an aperture in an abdominal wall.

25. The method according to claim 22, wherein deploying is accomplished in a controlled and continuous manner.

26. The method according to claim 22, wherein prior to the transforming step or the attaching 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.

27. The method according to claim 22, wherein the attaching and the releasing steps are performed sequentially.

28. The method according to claim 22, wherein the attaching and the releasing steps are performed simultaneously.
