Abstract

Surgical connection apparatus comprises a support structure, a plurality of clips, which can be self-closing clips, each clip being releasably coupled to the support structure, and a plurality of barbs, each barb being coupled to the support structure, the barbs being separate from the clips, which are ejectable from the support structure independently of the barbs.

Claims

1. Surgical connection apparatus comprising:

a support structure, wherein said support structure comprises a first plurality of tubular members and second plurality of tubular members;

a plurality of self-closing clips, each clip being, slidably disposed in one of said first plurality of tubular members, wherein the clips are configured to elect and release from the first plurality of tubular arms; and

a plurality of barbs, each of the plurality of barbs being slidably disposed in one of said second plurality of tubular members, wherein a distal end of said each of the plurality of barbs is configured to extend from a distal portion of said each of second plurality of tubular members and retract back into said distal portion of said each of second plurality of tubular members.

2. The apparatus of claim 1 further including a first plunger movably coupled to said support structure and a pusher disposed in each of said first plurality of tubular members, each pusher having a proximal end being secured to said plunger and a distal end portion coupled to a respective clip so that movement of said plunger moves all of said clips therewith.

3. The apparatus of claim 2 wherein each clip has a memory set closed configuration, when said clips are disposed in said first plurality of tubular members each tubular member biases a respective clip away from said closed configuration, and when said clips are released from said tubular members said clips move toward their memory set closed configuration.

4. The apparatus of any one of claim 1 further including means for simultaneously deploying said clips.

5. The apparatus of claim 2 further including a second plunger movably coupled to said support structure, each barb having a distal end and a proximal end, said second plunger being coupled to each barb proximal end so that said second plunger moves all of said barbs therewith.

6. The apparatus of claim 1 wherein each barb has a distal portion with a memory set hook configuration, when said barb distal end portions are disposed in said second plurality of tubular members each tubular member biases a respective barb distal end portion away from said hook configuration, and when said barb distal end portions are extended away from said tubular members said barbs move toward their memory set hook configuration.

7. The apparatus of claim 1 further including means for simultaneously deploying said barbs.

8. The apparatus of claim 1 further including means for simultaneously deploying said clips and means for simultaneously deploying said barbs independently of said clips.

9. Surgical connection apparatus comprising:

a support structure comprising a first plurality of arms and a second plurality of arms wherein the first plurality of arms forms a first plurality of paths and the second plurality of arms forms a second plurality of paths;

a plurality of clips, each clip being slidably disposed in one path of the first plurality of paths, wherein the clips are configured to eject and release from the first plurality of arms; and

a plurality of barbs, each of the plurality of barbs being longitudinally slidably disposed in one path of the second plurality of paths, wherein a distal end of each of the plurality of barbs is configured to extend from a distal portion of each of the second plurality of paths and retract back into the distal portion of each of the second plurality of paths, wherein the clips are separate from the barbs and are movable independently of the barbs and wherein the first plurality of arms and the second plurality of arms are arranged to form a plurality of arm pairs.

10. The apparatus of claim 9 further including a plunger movably coupled to said support structure and a pusher disposed in each of said first plurality of paths, each pusher having a proximal end being secured to said plunger and a distal end portion coupled to a respective clip so that movement of said plunger moves all of said clips therewith.

11. The apparatus of claim 10 further including a second plunger movably coupled to said support structure, each barb having a distal end and a proximal end, said second plunger being coupled to each barb proximal end so that said second plunger moves all of said barbs therewith.

12. The apparatus of claim 11 wherein said plungers are independently movable.

13. Surgical connection apparatus for connecting a first structure to a second structure, the connection apparatus comprising:

a support structure comprising a plurality of arm pairs, the plurality of arm pairs comprising a first plurality of tubular arms and a second plurality of tubular arms, a plurality of barbs coupled within the first plurality of tubular arms, wherein a distal end of each of the plurality of barbs is configured to extend from a distal portion of each of the first plurality of tubular arms and retract back into the distal portion of each of the first plurality of tubular arms, a plurality of clips being slidably coupled within the second plurality of tubular arms and independent of the barbs;

means for moving the barbs; and

means for ejecting and releasing the clips from the second plurality of tubular arms.

14. The apparatus of claim 13 wherein said clips comprise shape memory material, have a memory set closed configuration, and move toward said closed configuration when ejected from said support structure.

15. The apparatus of claim 14 wherein said clip ejecting and releasing means ejects said clips simultaneously.

16. The apparatus of claim 13 wherein said clip ejecting and releasing means ejects and releases said clips simultaneously.

17. The apparatus of claim 16 wherein said barb moving means provides means for extending the barbs from said distal portion of each of the first plurality of tubular arms and retracting the barbs into said distal portion of each of the first plurality of tubular arms.

18. The apparatus of any one of claims 15-17 wherein said barb moving means moves said barbs simultaneously.
