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 each movable from an unformed condition to a formed condition, 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 in the formed condition, and the plurality of second surgical fasteners apply a second, different compressive force to tissue in the formed condition, wherein the first surgical fasteners include legs extending from the first backspan and terminating in penetrating ends, the first backspan including first and second projections in both the unformed and formed conditions extending towards the tissue to define a first height, and apply the first compressive force, when the first surgical fasteners are in the formed condition, the plurality of first surgical fasteners being arranged in a first row, and the plurality of second surgical fasteners being arranged in a second row disposed laterally outward of the first row, the first and second backspans of the first and second fasteners being configured and dimensioned such that the first compressive force is greater than the second compressive force.

Abstract
A surgical fastener applying apparatus having a first jaw and a second jaw. The first jaw includes a cartridge body having plurality of surgical fasteners disposed therein. The plurality of surgical fasteners include 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, different 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.

- 19. A surgical fastener cartridge comprising a cartridge body including a plurality of surgical fasteners disposed therein each configured and dimensioned for application to tissue, and movable from an unformed condition to a formed condition, the plurality of surgical fasteners including a plurality of first surgical fasteners arranged in a first row and having first legs connected by a first backspan with a first configuration, and a plurality of second surgical fasteners arranged in a second row and having second legs connected by a second backspan with a second configuration, the first backspan including first and second projections in both the unformed and formed conditions extending towards the tissue to define a first height, and apply a first compressive force to the tissue, when the first surgical fasteners are in the formed condition, the second backspan including first and second projections in both the unformed and formed conditions extending towards the tissue to define a second height, and apply a second compressive force to the tissue, when the second surgical fasteners are in the formed condition, the first height being different than the second height such that the first compressive force is different than the second compressive force, wherein the first legs extend from the first backspan and terminate in penetrating ends, and the second legs extend from the second backspan and terminate in penetrating ends, the first and second projections extending from the first backspan being curved in configuration, and the first and second projections extending from the second backspan being curved in configuration.
