Abstract

Specifically, the anastomosis device of the present invention provides an anastomosis ring; such as but not limited to a ring of staples, in the form of an oval or ellipse. One specific embodiment of the present invention is a side to end anastomotic stapler with a row of staples formed in an elliptical pattern. Another embodiment of the present invention is a pair of anastomotic compression rings formed in an ellipse. A further embodiment of the invention is compression disc, rather than open ring structure.

Claims

1. A surgical resection and reconstruction method for a tubular body lumen comprising the steps of:

Providing a surgical anastomotic apparatus having an elongate tubular body and elements forming a closed loop anastomotic ring in the reconstructed hollow lumen and in a general anastomosis plane for reconstruction of the body lumen, wherein the anastomotic ring is non-circular, and wherein the elements of the surgical anastomotic apparatus have a dimension greater in one direction within the anastomosis plane than in an orthogonal direction in the anastomosis plane, whereby the greater dimension defines a long axis for the elements of the surgical anastomotic apparatus; and

At least one of inserting and withdrawing the elongate tubular body and ring through the interior of the body lumen and longitudinally along an interior portion of the body lumen with the long axis of the elements of the surgical anastomotic apparatus generally parallel with the axis of the tubular body lumen.

2. The method of claim 1 wherein the anastomotic ring is one of an oval and an ellipse.

3. The method of claim 2 wherein the surgical anastomotic apparatus is a surgical stapler and the method includes both inserting and withdrawing the surgical stapler through the body lumen with the long axis of the elements of the surgical stapler generally parallel with the axis of the tubular body lumen.

4. The method of claim 2 wherein the surgical anastomotic apparatus is a pair of open center compression rings.

5. The method of claim 4 wherein the pair of open center compression rings are withdrawn through the body lumen with the long axis of the rings generally parallel with the axis of the tubular body lumen.

6. The method of claim 2 wherein the surgical anastomotic apparatus is a pair of closed center compression discs.

7. The method of claim 6 wherein the pair of closed center compression discs are withdrawn through the body lumen with the long axis of the discs generally parallel with the axis of the tubular body lumen.

8. The method of claim 6 wherein the discs are frangible and further including the step of having the discs disintegrate into smaller components when the anastomosis site has healed.

9. The method of claim 1 wherein the surgical anastomotic apparatus is a surgical stapler, wherein the elements forming a closed loop anastomotic ring are a stapler anvil and stapler head, and the method includes both inserting and withdrawing the surgical stapler through the body lumen with the long axis of the anvil and head of the surgical stapler generally parallel with the axis of the tubular body lumen.

10. The method of claim 1 wherein the surgical anastomotic apparatus is a pair of open center compression rings.

11. The method of claim 10 wherein the pair of open center compression rings are substantially elliptical and are withdrawn through the body lumen with the long axis of the rings generally parallel with the axis of the tubular body lumen.

12. The method of claim 10 wherein the rings are substantially elliptical and are frangible and further including the step of having the rings disintegrate into smaller components when the anastomosis site has healed.

13. The method of claim 1 further including forming the closed loop anastomotic ring with staples without the step of trimming the tissue of the lumen within the anastomotic ring with the anastomotic device.

14. The method of claim 13, wherein the anastomosis site is at the side of at least one lumen portion wherein the closed loop anastomotic ring will have an interior closed by the untrimmed tissue of the side of the lumen while the anastomotic site is healing, and wherein the untrimmed tissue of the side of the lumen is not present after the anastomotic site is healed.

15. A surgical resection and reconstruction method for a tubular body lumen comprising the steps of:

Providing a surgical anastomotic apparatus having elements forming a closed loop anastomotic ring in the reconstructed hollow lumen and in a general anastomosis plane for reconstruction of the body lumen, wherein the anastomotic ring is non-circular, and wherein the elements of the surgical anastomotic apparatus have a dimension greater in one direction within the anastomosis plane than in an orthogonal direction in the anastomosis plane, whereby the greater dimension defines a long axis for the elements of the surgical anastomotic apparatus, wherein the surgical anastomotic apparatus is a pair of open center compression rings and wherein the rings are frangible;

At least one of inserting and withdrawing the surgical anastomotic apparatus through the body lumen with the long axis of the elements of the surgical anastomotic apparatus generally parallel with the axis of the tubular body lumen; and

further including the step of having the rings disintegrate into smaller components when the anastomosis site has healed.

16. A surgical resection and reconstruction method for a tubular body lumen comprising the steps of:

Providing a surgical anastomotic apparatus having elements forming a closed loop anastomotic ring in the reconstructed hollow lumen and in a general anastomosis plane for reconstruction of the body lumen, wherein the anastomotic ring is non-circular, and wherein the elements of the surgical anastomotic apparatus have a dimension greater in one direction within the anastomosis plane than in an orthogonal direction in the anastomosis plane, whereby the greater dimension defines a long axis for the elements of the surgical anastomotic apparatus, and wherein the surgical anastomotic apparatus is a pair of closed center compression discs; and

At least one of inserting and withdrawing the surgical anastomotic apparatus through the body lumen with the long axis of the elements of the surgical anastomotic apparatus generally parallel with the axis of the tubular body lumen.

17. The method of claim 16 wherein the pair of closed center compression discs are substantially elliptical and are withdrawn through the body lumen with the long axis of the discs generally parallel with the axis of the tubular body lumen.

18. The method of claim 16 wherein the discs are substantially elliptical and are frangible and further including the step of having the discs disintegrate into smaller components when the anastomosis site has healed.
