Abstract

The present invention is directed to tissue closure devices for closing a tissue opening, including one or more closure components, each closure component having a first member and a second member, each of the first and second members having a first surface that adheres to a tissue surface proximate to the tissue opening, each of the first and second members having a second surface substantially orthogonal to the first surface, and each of the first and second members having a transitional region between the first surface and the second surface which is contoured to evert an edge of the tissue opening upon the drawing together of the first and second members. The present invention is also directed to systems and kits, dressing systems, and methods for tissue repair and closure.

Claims

1. A closure device for closing a tissue opening, comprising:

one or more closure components, each closure component comprising a first member and a second member;

each of the first and second members having a first surface that adheres to a tissue surface proximate to the tissue opening, the first surface having at least one adhesive;

each of the first and second members having a second surface wherein at least one alignment member is positioned, the at least one alignment member extending into the body of each of the respective first and second member, the second surface and body portion of each respective first and second member being further structured to receive a second alignment member; and

each of the first and second members having a transitional region between the first surface and the second surface which is contoured to evert an edge of the tissue opening upon the drawing together of the first and second members by the engagement of the at least one alignment member.

2. The closure device of claim 1, wherein each of the alignment members has a locking mechanism.

3. The closure device of claim 2, wherein the first member and the second member are identical.

4. The closure device of claim 1, wherein the alignment members comprise at least one of a ball and socket mechanism, a ball and slot mechanism, a ratchet mechanism, a suture ligature, magnets, a photobonded mechanism, a staple, and a lock and key mechanism.

5. The closure device of claim 4, wherein the alignment members are ratchet mechanisms including a plurality of teeth.

6. The closure device of claim 2, wherein the first and second members are releasably coupled.

7. The closure device of claim 5, wherein said plurality of teeth are non-uniform in height.

8. The closure device of claim 7, wherein each alignment member of each closure component has three teeth, and wherein the tooth on each said alignment member farthest from the second surface of each said alignment member has a height greater than the other two teeth on each said alignment member.

9. The closure device of claim 1, further comprising a second adhesive.

10. The closure device of claim 1, wherein the alignment members are positioned substantially in a lower one third portion of the at least first and second members with respect to the height dimension of the at least first and second members.

11. The closure device of claim 5, wherein the vertical height of the teeth is in the range of approximately 0.005 cm to approximately 0.1 cm.

12. The closure device of claim 11, wherein the teeth of each alignment member are positioned closer to the second surface of the member than to the end of the alignment member as measured along a principle axis of the alignment member.

13. The closure device of claim 5, further comprising a locking mechanism comprising a hollow section for engagement of at least one tooth.

14. A method for closing a tissue opening, comprising:

positioning a closure device for closing a tissue opening, the closure device comprising one or more closure components, each closure component comprising a first member and a second member, each of the first and second members having a first surface that adheres to a tissue surface proximate to the tissue opening, the first surface having at least one adhesive, each of the first and second members including a second surface having at least one alignment member positioned therein, the second surface and a portion of each member being further structured to receive a second alignment member;

drawing the first and second members into proximity such that each first member receives the alignment member of each second member, and each second member receives the alignment member of each first member;

everting an edge of the tissue opening upon the drawing together of the first and second members, said first and second members having a transitional region between the first and second surfaces which is contoured to evert an edge of the tissue opening; and

securing each of the first and second members to a tissue surface.

15. The method of claim 14, wherein each of the alignment members further comprises a locking mechanism.

16. The method of claim 14, wherein the alignment members are ratchet mechanisms including a plurality of teeth.

17. The method of claim 16, further comprising a locking mechanism comprising a hollow section for engagement of at least one tooth.

18. The method of claim 14, wherein the alignment members provide a vertical force substantially orthogonal to a plane of the tissue opening on at least one edge of the tissue opening.

19. The method of claim 14, wherein the alignment members are positioned substantially in a lower one third portion of the at least first and second members with respect to the height dimension of the first and second members.

20. The method of claim 16, wherein the vertical height of the teeth is in the range of approximately 0.005 cm to approximately 0.1 cm.
