Method of stapling anatomical tissue
First Claim
1. A method of stapling biological tissue comprising the steps ofpositioning a first plurality of staples in at least two rows on a first side of the biological tissue to be stapled;
- positioning a first plurality of staple-forming anvils in at least two rows on the first side of the biological tissue such that each row of staple-forming anvils is adjacent at least one row of staples;
positioning a second plurality of staples in at least two rows on a second side of the biological tissue in alignment with the first plurality of staple-forming anvils;
positioning a second plurality of staple-forming anvils in at least two rows on the second side of the biological tissue in alignment with the first plurality of staples;
piercing the biological tissue from the first side of the biological tissue with tissue piercing legs of the first plurality of staples;
piercing the biological tissue from the second side of the biological tissue with tissue piercing legs of the second plurality of staples;
bending the tissue piercing legs of the first plurality of staples against the second plurality of staple-forming anvils on the second side of the biological tissue;
bending the tissue piercing legs of the second plurality of staples against the first plurality of staple-forming anvils on the first side of the biological tissue; and
cutting the biological tissue between the rows of staples such that at least two rows of staples extending through the biological tissue in opposite directions are disposed on each side of the cut.

Abstract
A method for a surgical stapler for applying multiple rows of surgical staples to biological tissue which includes a pair of opposed jaws adapted to receive tissue therebetween, a plurality of surgical staples and staple-forming anvils carried by each jaw in alignment with the staples and staple-forming anvils carried by the other jaw, and a mechanism for driving the tissue penetrating legs of the staples through the biological tissue and bending the legs against opposed anvils on the opposite side of the tissue to produce rows of finished surgical staples on both sides of the tissue being ligated. The staples and anvils in each of the jaws are arranged in spaced, parallel rows, with each row of staples being adjacent a row of anvils and adjacent rows of staples and anvils being either longitudinally staggered or aligned. Further, the staples and anvils are carried either alone or in combination in a pair of cartridges held by the opposed jaws, which are either linear or curved depending on the procedure to be performed with the surgical stapler.
