Elliptical intraluminal surgical stapler for anastomosis

An elliptical surgical stapler, comprising:

• a head in which a plurality of staples are stored, the head including an annular facing surface;
• an anvil coupled to the head including an anvil surface shaped and dimensioned for forming the staples upon actuation of the surgical stapler, the anvil including an annular facing surface opposed to the facing surface of the head for mating engagement therewith;
• wherein upon mating engagement the annular facing surface of the anvil and the annular facing surface of the head the annular facing surfaces of the anvil and head define an oblique mating plane on which the anvil and head create an elliptical staple line due to angled elliptical profiles of the facing surfaces of the anvil and the head.

An intraluminal surgical stapler, comprising:

• a head in which a plurality of staples are stored, the head including an elliptical, annular facing surface;
• an anvil coupled to the head including an anvil surface shaped and dimensioned for forming the staples upon actuation of the surgical stapler, the anvil including an elliptical, annular facing surface opposed to the facing surface of the head for mating engagement therewith, and upon mating engagement the annular facing surface of the anvil and the annular facing surface of the head define a mating plane;
• wherein the mating plane is obliquely oriented relative to a longitudinal axis of the head.
