Visceral Anchors For Purse-String Closure of Perforations
First Claim
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.

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.

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. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

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. - View Dependent Claims (21, 22, 23, 24)
