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.

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.

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. - View Dependent Claims (17, 18)
