Abstract

Medical devices and related methods for closing a perforation in a bodily wall The medical device generally includes a suture having opposing first and second ends and a set of visceral anchors. Each visceral anchor includes a crossbar having opposing ends and a suture slidably attached thereto. Each visceral anchor is passed through the bodily wall adjacent the periphery of the perforation. The ends of the suture are tensioned to reduce the distance between the visceral anchors and compress the bodily wall around the perforation. The ends of the suture are secured to maintain the compression of the bodily wall and close the perforation.

Claims

1. A medical device for closing a perforation in a bodily wall, the medical device comprising:

a suture having opposing first and second ends;

a set of visceral anchors, each visceral anchor including a cross bar having opposing ends, the suture being slidably attached to each of the crossbars;

the first and second ends of the suture capable of being independently tensioned for translating the suture relative to each of the visceral anchors and closing the perforation.

2. The medical device of claim 1, wherein the tensioning of the suture reduces the distance between the visceral anchors for closing the perforation in a purse-string fashion.

3. The medical device of claim 1, wherein each visceral anchor is positioned on one side of the bodily wall, and wherein the first and second ends of the suture are positioned on the opposite side of the bodily wall.

4. The medical device of claim 1, wherein each visceral anchor includes a passageway between the opposing ends of the crossbar the passageway having an entrance and an exit through which the suture passes, the entrance and exit being spaced apart a distance less than an outer diameter of the crossbar greater than 0.001 mm and less than 1.0 mm.

5. The medical device of claim 1, further comprising an overtube for delivery of the set of visceral anchors, the overtube having a set of lumens, each lumen receiving a visceral anchor, portions of the suture located between the visceral anchors extending outside the lumens at a distal end of the overtube.

6. The medical device of claim 5, further comprising a set of puncture needles slidably received with the set of lumens, the set of puncture needles receiving the set of visceral anchors therein.

7. A visceral anchor for connecting a suture to tissue, the visceral anchor comprising:

a cross bar having first and second opposing ends, the cross bar defining a longitudinal axis; and

a passageway located between the opposing ends of the cross bar, the passageway slidably receiving the suture therein;

the passageway having an entrance and an exit through which the suture passes, the entrance and exit being spaced apart a distance less than an outer diameter of the crossbar greater than 0.001 mm and less than 1.0 mm.

8. The visceral anchor of claim 7, wherein the entrance and exit are spaced apart a distance greater than 0.001 mm and less than 1 mm.

9. The visceral anchor of claim 7, wherein the passageway extends parallel to the longitudinal axis.

10. The visceral anchor of claim 7, wherein the cross bar is constructed of a cannula having a tubular wall defining a lumen, a first opening in the wall defining the entrance, a second opening in the wall defining the exit.

11. The visceral anchor of claim 10, wherein the first opening is a first longitudinal slot formed in the first end of the cannula, and the second opening is a second longitudinal slot formed in the second end of the cannula, and wherein the tubular wall includes a strip portion extending between the first and second slots.

12. The visceral anchor of claim 7, further comprising a wire connected to the crossbar, the passageway being defined between the wire and the cross bar.

13. The visceral anchor of claim 11, wherein the cross bar is constructed of a cannula having a tubular wall defining a lumen, the tubular wall defining first and second openings, a first end of the wire passing through a first opening, a second end of the wire passing through the second opening.

14. The visceral anchor of claim 13, wherein the first and second ends of the wire are secured within the lumen of the cannula.

15. The visceral anchor of claim 13, further comprising a rod connected to the cross bar, the passageway being defined between the rod and the crossbar.

16. The visceral anchor of claim 15, wherein the cross bar is constructed of a cannula having a tubular wall defining a lumen, and wherein the rod is secured within the lumen of the cannula.

17. The visceral anchor of claim 16, wherein the tubular wall defines an opening in communication with the lumen, the opening providing access to the rod.

18. The visceral anchor of claim 16, wherein the rod extends parallel with the longitudinal axis.

19. The visceral anchor of claim 16, wherein the rod extends perpendicular to the longitudinal axis.

20. A method for closing a perforation in a bodily wall using a set of visceral anchors connected to a suture, each visceral anchor including a cross bar slidably attached to the suture, the method comprising the steps of:

passing each visceral anchor through the bodily wall adjacent the periphery of the perforation, each visceral anchor being on a distal side of the bodily wall, the ends of the suture being on a proximal side of the bodily wall;

tensioning the ends of the suture to reduce the distance between the visceral anchors and compress the bodily wall around the perforation; and

securing the ends of the suture to maintain the compression of the bodily wall and close the perforation.

21. The method of claim 20, wherein the passing step includes positioning the set of visceral anchors around the perforation to permit closing of the perforation in a purse-string fashion.

22. The method of claim 20, wherein the passing step includes positioning the set of visceral anchors sequentially around the perforation in a semi-annular or annular shape.

23. The method of claim 20, wherein the passing step includes positioning the set of visceral anchors sequentially on opposite sides of the perforation.

24. The method of claim 20, wherein the tensioning step includes independently tensioning the ends of the suture.
