Abstract

A clip for suturing opposed ends of severed tissue. The clip has a body with a first end terminating in a needle and a second end having an opening thereat. The body may also include a bite portion between the first and second ends applying a biasing force to hold the suturing clip in either a default open or default closed condition, wherein the needle is remote from the opening in the open condition and in proximity to the opening in the closed condition. The body may also include a footpad adjacent the needle, wherein the footpad pinches the opposing ends of the severed tissue against the body adjacent to the opening when the clip is in the closed condition. The clips may be applied by a surgical device, which is also disclosed.

22. The suturing clip of claim 21, wherein said first extension member, said second extension member, and said needle arm are connected to each other via a pin at said bite portion of said clip.

23. The suturing clip of claim 22, wherein said needle arm forms said needle at said first end of said clip.

24. The suturing clip of claim 21, wherein said first extension member and said second extension member form said needle receiving ring at said second end of said body.

25. The suturing clip of claim 22, wherein said first extension member and said second extension member are pivotable about said pin to form said needle receiving ring when said first extension member and said second extension member are brought adjacent to each other.

26. A suturing clip comprising a wire strand having a first end tapering into a needle, a second end configured to form a needle receiving ring to receive said needle, and a bite portion therebetween, said bite portion biasing said clip in either one of an open condition in which said needle is remote from said needle receiving ring and a closed condition in which said needle is at least partially within said needle receiving ring.
