Non-circular compression anastomotic devices

A compression anastomotic device for reconstruction of a tubular body lumen comprising:

• A pair of interconnectable closed center center compression discs adapted to form a closed loop anastomotic ring in the reconstructed hollow lumen, with the anastomotic ring defining an anastomotic plane, wherein the anastomotic ring is non-circular in plan view, and wherein the compression discs 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 compression rings, whereby at least one of inserting and withdrawing the anastomotic apparatus through the body lumen with the long axis of the discs of the anastomotic device generally parallel with the axis of the tubular body lumen.

A esophageal-gastro-intestinal compression anastomotic device for reconstruction of a tubular body esophageal-gastro-intestinal lumen comprising:

• A pair of interconnectable compression members adapted to form a closed loop anastomotic ring in the reconstructed hollow esophageal-gastro-intestinal lumen, with the anastomotic ring defining an anastomotic plane, wherein the compression members are non-circular in plan view, and wherein the compression members have an outer peripheral 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 compression members, whereby at least one of inserting and withdrawing the anastomotic apparatus through the body esophageal-gastro-intestinal lumen with the long axis of the anastomotic device generally parallel with the axis of the tubular body lumen.
