Abstract

Devices and methods for biological tissue closure are disclosed. Arteriotomy closure and hemostasis devices and methods are disclosed. A device that can provide a lateral tension across an opening in the tissue and apply energy to seal the tissue is disclosed. Methods for using the device are also disclosed.

Claims

1. A method for closing an opening in a biological tissue comprising:

advancing a tensioning element into the opening, wherein the opening is located between an outer surface and an inner surface of a tissue wall;

tensioning the opening with the tensioning element in a lateral direction so that the opening collapses in a longitudinal direction; and

applying a sealer to the opening.

2. The method of claim 1, wherein a first part of the wall is brought to less than about 0.51 mm away from a second part of the wall.

3. The method of claim 1, wherein a first part of the wall is brought to less than about 0.38 mm away from a second part of the wall.

4. The method of claim 1, wherein a first part of the wall is brought to more than about 0.25 mm away from a second part of the wall.

5. The method of claim 1, wherein the sealer comprises energy.

6. The method of claim 5, wherein the energy comprises acoustic energy.

7. The method of claim 6, wherein the energy further comprises RF energy.

8. The method of claim 5, wherein the energy comprises RF energy.

9. The method of claim 5, wherein the energy comprises conductive heat energy.

10. The method of claim 5, wherein the energy comprises inductive heat energy.

11. The method of claim 5, wherein the energy comprises microwave heat energy.

12. The method of claim 1, wherein the sealer comprises an adhesive.

13. The method of claim 1, wherein the sealer comprises a filler.

14. The method of claim 1, wherein the sealer comprises a liquid.

15. The method of claim 12, wherein the adhesive comprises a liquid adhesive.

16. The method of claim 1, further comprising aiming the sealer at the opening.

17. The method of claim 16, wherein aiming comprises deploying an aiming device into the opening.

18. The method of claim 1, further comprising deploying a web into the opening.

19. The method of claim 18, wherein deploying comprises leaving the web in the opening at least for an extended period following closing the opening.

20. The method of claim 19, wherein deploying comprises leaving the web in the opening at least until the web is entirely bioabsorbed.

21. The method of claim 1, wherein at least a portion of the opening is an arteriotomy.

22. The method of claim 1, further comprising inserting a hollow member into the opening, and further performing a first surgical procedure through the hollow member, and wherein tensioning then is performed with the hollow member.

23. A method for closing an opening in a biological tissue, comprising:

inserting a closure device into the opening;

bringing a first part of the opening adjacent to a second part of the opening in a longitudinal direction by urging the opening apart in a lateral direction with the closure device while the closure device is positioned within the opening, wherein the opening is located between an outer surface and an inner surface of a tissue wall; and

applying a sealer to the opening.

24. The method of claim 23, wherein the first part of the opening is brought to less than about 0.51 mm away from the second part of the opening.

25. The method of claim 24, wherein the first part of the opening is brought to less than about 0.38 mm away from the second part of the opening.

26. The method of claim 25, wherein the first part of the opening is brought to more than about 0.25 mm away from the second part of the opening.

27. A method for closing an opening, comprising:

inserting a first elongated member into the opening;

inserting a second elongated member into the opening; and

laterally expanding the opening, wherein expanding comprises applying one or more forces on the opening with the first and second elongated members to expand the opening in a first direction so that the opening closes in a second direction, wherein the opening is located between an outer surface and an inner surface of a tissue wall.

28. The method of claim 27, wherein the opening is an arteriotomy.
