Abstract

The self securing suture includes a suture having at least one terminal end and a toggle, formed of suture material, at the suture'"'"'s terminal end. In one embodiment, the suture toggle is a bar. In another embodiment the suture is a wire and the toggle is a wire element toggle. The wire element toggle is a double strand segment or an open loop segment. The suture delivery system includes a slotted needle configured such that a protruding tab or leg of the toggle bar fits within slot of the needle. For wire sutures, the open loop wire element toggle fits within the slotted needle. In another embodiment, a depending wire tip, from the wire element toggle, fits within the slot in the needle. In either situation, after the needle pierces the bodily structure, tissue or organ, the tab, leg, depending wire tip or open loop wire segment coacts with the inboard portion of the bodily structure, tissue or organ, and, as the delivery needle is withdrawn, the toggle at the terminal end of the suture remains in the bodily structure, tissue or organ. The toggle is then fully deployed being generally normally disposed (perpendicular) to the length or axial center line of the suture. When the suture has two suture toggles, one at each terminal end of a suture thread or suture wire body, the physician can easily deploy the suture toggles on either side of an arterial puncture site (for example), tie off the suture thread or suture wire body and thereby close the puncture.

Claims

1. A self securing suture comprising a suture thread having at least one terminal end and a toggle at said terminal end, said toggle disposed at an acute angle with respect to said suture thread, said suture thread and said toggle are made of substantially the same biocompatible material and wherein said suture thread and said toggle at said terminal end are metal wire.

2. A suture as claimed in claim 1 wherein said toggle is a wire element disposed on said suture terminal end.

3. A self securing suture comprising a suture body having at least one terminal end and terminal end body segment and defining a toggle thereat, said toggle disposed at an acute angle with respect to said terminal end body segment, said toggle is substantially fixed at said acute angle with respect to said terminal end body segment.

4. A suture as claimed in claim 3 wherein said terminal end body segment is substantially fixed with respect to said toggle and said suture body is made of a material from the group of a metal wire material, a nylon material, and a biocompatible material.

5. A suture as claimed in claim 3 wherein said suture body and said toggle are made of different biocompatible materials.

6. A suture as claimed in claim 3 wherein said toggle includes a distal and a proximal segment respectively disposed at an obtuse and an acute angle with respect to said terminal end body segment.

7. A self securing suture comprising a suture body having at least one terminal end and terminal endbody segment and defining a toggle thereat, said toggle disposed at an acute angle with respect to said terminal end body segment, wherein said toggle includes first and second aligned segments, said first and second aligned segments and said suture body disposed in a singular plane, said first segment defining said acute angle with respect to said terminal end body segment, and said second segment defining an obtuse angle with respect to said terminal end body segment.

8. A suture as claimed in claim 7 wherein said suture body is made of a material from the group of a metal wire material, a nylon material, and a biocompatible material.

9. A suture as claimed in claim 7 wherein said suture body and said toggle are made of different biocompatible materials.

10. A suture as claimed in claim 7 wherein said toggle is substantially fixed at said acute angle with respect to said terminal end body segment.

11. A suture as claimed in claim 7 wherein said toggle includes a distal and a proximal segment respectively disposed at an obtuse and an acute angle with respect to said terminal end body segment.
