Abstract

Medical devices and related methods are provided for closing a perforation in a bodily wall. The medical device generally includes a set of tissue anchors and an elongate tensioning member. Each anchor includes a crossbar having opposing ends and defining a longitudinal axis. A strand is connected to the crossbar at a location between the opposing ends and projects away from the longitudinal axis. The strand includes a distal end connected to the crossbar and a proximal end having a first connector. The elongate tensioning member is structured to selectively engage and disengage the first connector. The strands of the anchor are capable of being tensioned and fixed together for closing the perforation. The tensioning member is removed after the strands are fixed together.

Claims

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

a set of tissue anchors, the set of tissue anchors including a first tissue anchor and a second tissue anchor, each tissue anchor including a crossbar and a strand, the crossbar having opposing ends and defining a longitudinal axis, the strand connected to the crossbar at a location between the opposing ends and projecting away from the longitudinal axis, the strand having a distal end connected to the crossbar and a proximal end having a first connector; and

an elongate tensioning member structured to selectively engage and disengage the first connector, the strands capable of being tensioned and fixed together for closing the perforation, the elongate tensioning member including an elongate suture having opposed first and second ends, wherein the suture selectively engages and disengages the first connectors of the tissue anchors;

wherein the elongate suture extends from the first end to a first portion folded over to form a first looped section, from the first looped section to a second portion folded over to form a second looped section, and from the second looped section to the second end, and wherein the first connectors of the first and second tissue anchors selectively receive the first and second looped sections, and wherein the device further includes an elongate holding member selectively engaging the first and second looped sections while the first and second looped sections are received by the first connectors.

2. The medical device of claim 1, wherein the strand is fixedly attached to the crossbar.

3. The medical device of claim 1, wherein the strand and the crossbar are integrally and unitarily formed as a single piece.

4. The medical device of claim 1, wherein the strand has a length in the range of about 20 mm to about 30 mm.

5. The medical device of claim 1, further comprising a suture lock for fixing the strands together.

6. The medical device of claim 1, wherein the first connector is a closed loop.

7. The medical device of claim 1, wherein the elongate tensioning member includes a distal end having a second connector, the first and second connectors structured to selectively engage and disengage each other.

8. The medical device of claim 7, wherein the second connector is a J-shaped hook.

9. The medical device of claim 1, wherein the elongate suture includes an intermediate portion located between the first and second ends, wherein the intermediate portion of the suture is configured to selectively engage and disengage the first connector by the medical professional releasing at least one of the first and second ends.

10. The medical device of claim 1, wherein the first connectors of the first and second tissue anchors have first and second closed loops, respectively, wherein the first and second closed loops selectively receive the first and second looped sections, respectively.

11. The medical device of claim 1, wherein the first connector is in the shape of one of a J-shaped hook and a closed loop.

12. The medical device of claim 1, wherein each of the first connectors receive two portions of the elongate suture to form the looped sections.

13. The medical device of claim 1, wherein the first connectors receiving the first and second looped sections each includes the elongate suture passing through the first connector, folding over, and again passing through the first connector.

14. The medical device of claim 12, wherein each first connector includes a single aperture.

15. The medical device of claim 13, wherein each first connector includes a single aperture.
