Abstract

A suturing instrument including multiple needle and suture assemblies that are at least partially disposed within the suturing instrument allows a surgeon to place multiple sutures intercorporally without having to remove the instrument from a surgical site and reload the instrument between placing each suture. The suturing instrument includes an elongate body member that includes a distal portion defining an opening. The suturing instrument further includes a first needle disposed within the opening, a second needle disposed within the opening, and a needle deployment mechanism disposed at least partially within the elongate body member and connectable sequentially to the first needle and the second needle.

Claims

1-14. -14. (canceled)

15. A suturing instrument comprising:

an elongate body member including a distal portion defining a needle compartment for storing at least two needles;

a needle deployment mechanism disposed at least partially within the elongate body member, the needle deployment mechanism including a needle carrier that is sequentially connectable to the at least two needles; and

a needle catch for sequentially receiving and capturing the at least two needles.

16. The suturing instrument of claim 15 wherein each of the at least two needles has a suture attached thereto.

17. The suturing instrument of claim 15 further comprising a handle disposed opposite the distal portion of the elongate body member.

18. The suturing instrument of claim 15 wherein the elongate body member is adapted to access organs or tissue within a body of a patient.

19. The suturing instrument of claim 15 wherein the needle carrier defines a lumen for sequentially receiving each of the at least two needles.

20. The suturing instrument of claim 15 wherein the elongate body member includes a bend.

21. The suturing instrument of claim 15 wherein the elongate body member includes two bends.

22. The suturing instrument of claim 15 wherein the distal portion of the elongate body member is rotatable relative to a remainder of the elongate body member.
