Variable compression surgical fastener cartridge
First Claim
1. A surgical fastener applying apparatus comprising a first jaw and a second jaw, the first jaw including a cartridge body having a plurality of surgical fasteners disposed therein, the plurality of surgical fasteners including a plurality of first surgical fasteners having a first backspan with a first configuration, and a plurality of second surgical fasteners having a second backspan with a second configuration, wherein the first configuration is different than the second configuration such that the plurality of first surgical fasteners apply a first compressive force to tissue upon formation, and the plurality of second surgical fasteners apply a second, different compressive force to tissue upon formation;
- wherein the plurality of first surgical fasteners are arranged in a first row, and the plurality of second surgical fasteners are arranged in a second row laterally outward of the first row, and the first and second backspans of the first and second fasteners are configured and dimensioned such that the first compressive force is greater than the second compressive force, and the backspan of the plurality of first surgical fasteners has a twisted configuration defining a first height, and the backspan of the plurality of second surgical fasteners has a twisted configuration defining a second height, the first height being greater than the second height.
