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wire segment coacts with the inboard portion of the bodily structure, tissue or organ, and, as the delivery needle is withdrawn, the toggle at the terminal end of the suture remains in the bodily structure, tissue or organ.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.

- 23. A self securing suture comprising a suture having at least one terminal end and a toggle at said terminal end, said toggle includes a catch element protruding therefrom and said suture is metal wire and said toggle is a wire element disposed on said suture terminal end wherein said wire toggle element includes a wire catch element depending therefrom.
- 35. A suture delivery system comprising a needle including a lumen, a piercing terminal end segment and an open ended slot, open at said piercing end segment, and a suture having at least one terminal end and a toggle at said suture terminal end, and a catch element protruding from said toggle, said catch element adapted to seat within said needle slot.
- 44. A suture delivery system comprising a needle including a lumen, a piercing terminal end segment and an open ended slot, open at said piercing end segment, and a metal wire suture having at least one terminal end and a wire element toggle disposed on said suture terminal end at an angle with respect to said suture wire and a catch element depending from said wire toggle element, said catch element adapted to seat within said needle slot.
- 49. A suture delivery system comprising a needle including a lumen, a piercing terminal end segment and an open ended slot, open at said piercing end segment, and a suture having at least one terminal end and a toggle at said suture terminal end, said toggle disposed at an acute angle with respect to said suture such that said toggle is adapted to be captured via said acute angle in said needle slot.
