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; and
a set of visceral anchors, each visceral anchor including a crossbar having opposing ends and a wire having first and second ends secured to the crossbar, the crossbar being elongated to define a longitudinal axis, the first and second ends of the wire being longitudinally spaced apart, the crossbar being tubular to define an interior and an exterior, the wire projecting from the interior and extending along the exterior to define the loop, the first and second ends of the wire being secured spaced apart within the lumen to the opposing ends of the crossbar the wire forming a loop through which the suture extends, 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.

9. A visceral anchor for connecting a suture to tissue, the visceral anchor comprising:
-
a crossbar having first and second opposing ends, the crossbar defining a longitudinal axis, the crossbar having a tubular wall defining a lumen and an exterior, the tubular wall having first and second openings longitudinally spaced apart; and a wire having first and second ends extending through the first and second openings in the tubular wall, respectively, and the first and second ends are spaced apart and fixed to the tubular wall within the lumen, the wire projecting out from the tubular wall and extending along the exterior of the tubular wall to form a loop defining a passageway located between the opposing ends of the crossbar, 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
