Abstract

A system for closing an aperture in a biological tissue includes an implant deployment device with a frame arm and a clip operably disposed on the frame arm. A mesh attachment apparatus has a clip press with a body portion including a recess and at least one chamfered press operably disposed in the recess. The chamfered press is configured to move between an extended position protruding at least partially from said recess and a retracted position. The mesh attachment apparatus is configured to move the clip from an open position to a closed position to facilitate loading an implant onto the implant deployment device.

First claim

What is claimed is:

1. A surgical system comprising:
an implant deployment device including at least one frame arm and at least one clip rotatably coupled to the at least one frame arm; and
a mesh attachment apparatus comprising at least one clip press, the at least one clip press comprising:
a body portion including at least one recess; and
at least one chamfered press operably disposed in the at least one recess and configured to move between an extended position protruding at least partially from the at least one recess and a retracted position;

wherein the mesh attachment apparatus is configured to rotate the at least one clip from an open position to a closed position to facilitate loading an implant onto the implant deployment device, movement of the body portion towards the at least one frame arm urges the at least one clip towards the closed position when the at least one chamfered press is in the retracted position.

2. The system of claim 1 , wherein the mesh attachment apparatus further comprises a spring member disposed between the at least one chamfered press and the body portion.

3. The system of claim 2 , wherein the spring member biases the at least one chamfered press towards the extended position.

4. The system of claim 1 , wherein the at least one chamfered press includes at least one chamfered surface at a distal end of the chamfered press, the at least one chamfered surface defining an angle with respect to a side surface of the chamfered press; and at least one press surface.

5. The system of claim 4 , wherein the at least one chamfered surface includes a substantially linear chamfer.

6. A mesh attachment apparatus for use with an implant deployment device, comprising:
at least one clip press, the at least one clip press comprising:
a body portion including at least one recess; and
at least one chamfered press operably disposed in the at least one recess and configured to move between an extended position protruding at least partially from the at least one recess and a retracted position;

wherein the mesh attachment apparatus is configured to rotate at least one clip coupled to the implant deployment device from an open position to a closed position to facilitate loading an implant onto the implant deployment device, movement of the body portion towards a frame arm of the implant deployment device urges the at least one clip towards the closed position when the at least one chamfered press is in the retracted position.

7. The mesh attachment apparatus of claim 6 , wherein the mesh attachment apparatus further comprises a spring member disposed between the at least one chamfered press and the body portion.

8. The mesh attachment apparatus of claim 7 , wherein the spring member biases the at least one chamfered press towards the extended position.

9. The mesh attachment apparatus of claim 6 , wherein the at least one chamfered press includes at least one chamfered surface at a distal end of the chamfered press, the at least one chamfered surface defining an angle with respect to a side surface of the chamfered press; and at least one press surface.

10. The mesh attachment apparatus of claim 9 , wherein the at least one chamfered surface includes a substantially linear chamfer.

11. A method, comprising:
providing a mesh attachment apparatus for use with an implant deployment device, comprising:
at least one clip press, the at least one clip press comprising:
a body portion including at least one recess; and
at least one chamfered press operably disposed in the at least one recess and configured to move between an extended position protruding at least partially from the at least one recess and a retracted position;

wherein the mesh attachment apparatus is configured to rotate at least one clip coupled to the implant deployment device from an open position to a closed position to facilitate loading an implant onto the implant deployment device, movement of the body portion towards a frame arm of the implant deployment device urges the at least one clip towards the closed position when the at least one chamfered press is in the retracted position; and
using the mesh attachment apparatus to rotate the at least one clip of the implant deployment device from the open position to the closed position.

12. The method of claim 11 , wherein the mesh attachment apparatus further comprises a spring member disposed between the at least one chamfered press and said body portion, the spring member biasing the at least one chamfered press towards the extended position.

13. The method of claim 11 , wherein the at least one chamfered press includes at least one chamfered surface at a distal end of the chamfered press, the at least one chamfered surface defining an angle with respect to a side surface of the chamfered press; and at least one press surface.

14. The method of claim 13 , wherein the at least one chamfered surface includes a substantially linear chamfer.

15. The method of claim 11 , further comprising using the mesh attachment apparatus to releasably attach the implant to the at least one clip of the implant deployment device by compressing the implant onto the at least one clip in an open position and allowing the at least one chamfered surface rotate the at least one clip from the open position to the closed position.
