Abstract

Surgical clips which are particularly useful in the transoral invagination and fundoplication of the stomach to the esophagus. are disclosed. The clips include first and second arms joined by a bridge to form a substantially U-shape, and which are provided with a first structure adapted to prevent a movement of the clip in a direction perpendicular to a longitudinal axis of the clip after the clip is applied to tissue. In addition, the clips preferably also include a second structure adapted to prevent rotation of the clip about the longitudinal axis of the clip after the clip is applied to tissue.

Claims

1. A surgical clip, comprising:

a) a first arm;

b) a second arm;

c) a bridge connecting said first and second arms such that said first and second arms and said bridge are configured in a U-shape; and

d) a first structure adapted to prevent a movement of said clip in a direction perpendicular to a longitudinal axis of said clip after said clip is applied to said tissue.

2. A surgical clip according to claim 1, wherein:

said first structure is located between said first and second arms.

3. A surgical clip according to claim 2, wherein:

said first structure is a prong extending parallel to and between said first and second arms,

wherein said first and second arms, said prong and said bridge are together configured in an E-shape.

4. A surgical clip according to claim 3, wherein:

said prong is provided with at least one tissue irritator.

5. A surgical clip according to claim 3, wherein:

said prong has an end provided with a barb.

6. A surgical clip according to claim 1, wherein:

said prong has one of a sharp tip and a radiused tip.

7. A surgical clip according to claim 1, further comprising:

e) a second structure adapted to prevent rotation of said clip about said longitudinal axis of said clip after said clip is applied to said tissue.

8. A surgical clip according to claim 1, further comprising:

e) at least one deformable retainer extending from one of said arms, wherein said arms are relatively stiffer than said at least one deformable retainer.

9. A surgical clip according to claim 7, further comprising:

f) at least one deformable retainer extending from one of said arms, wherein said arms are relatively stiffer than said at least one deformable retainer, wherein said at least one deformable retainer is bifurcated into first and second portions, and said second portion of said at least one deformable retainer is said second structure adapted to prevent rotation.

10. A surgical clip according to claim 7, wherein:

said second structure includes one of inwardly-directed and outwardly-directed projection on at least one of said arms.

11. A surgical clip for insertion into tissue, comprising:

a) a first arm;

b) a second arm;

c) a bridge connecting said first and second arms such that said first and second arms extend in substantially a same direction; and

d) a first structure-adapted to prevent rotation of said clip about a longitudinal axis of said clip after said clip is applied to said tissue.

12. A surgical clip according to claim 11, further comprising:

e) at least one deformable retainer extending from one of said arms, wherein said arms are relatively stiffer than said at least one deformable retainer.

13. A surgical clip according to claim 12, wherein:

said at least one deformable retainer is bifurcated into first and second portions, and said first structure is said second portion of said at least one deformable retainer.

14. A surgical clip according to claim 11, wherein:

said first structure includes one of inwardly-directed and outwardly-directed projection on at least one of said arms.

15. A surgical clip according to claim 11, further comprising:

e) a prong extending parallel to and between said first and second arms,

wherein said first and second arms, said prong and said bridge are together configured in an E-shape.

16. A surgical clip according to claim 15, further comprising:

f) at least one deformable retainer extending from one of said arms, wherein said arms are relatively stiffer than said at least one deformable retainer.

18. A surgical clip according to claim 17, wherein:

said second and third widths are each approximately one-half said first width.

17. A surgical clip, comprising:

a) a first arm having a first width;

b) a first deformable retainer extending from said first arm, and having a second width less than said first width;

c) a first catch defined on said first arm adjacent said first retainer;

d) a second arm having substantially said first width;

e) a second deformable retainer extending from said second arm, and having a third width less than said first width,

f) a second catch defined on said second arm adjacent said second retainer,

wherein said second and third widths have a combined dimension not exceeding said first width; and

g) a bridge connecting said first and second arms such that said first and second arms extend in substantially a same direction.

19. A surgical clip, comprising:

a) a first arm;

b) a first deformable retainer extending from said first arm;

c) a first catch defined on said first arm adjacent said first retainer;

d) a second arm;

e) a second deformable retainer extending from said second arm, said second retainer being horizontally offset relative to said first retainer;

f) a second catch defined on said second arm adjacent said second retainer; and

g) a bridge connecting said first and second arms such that said first and second arms extend in substantially a same direction.
