Variable compression surgical fastener cartridge
First Claim
1. A tool assembly for use with a surgical fastener applying apparatus, the tool assembly comprising:
- a first jaw including a cartridge assembly having a plurality of surgical fasteners disposed within the cartridge assembly, each surgical fastener in the plurality of surgical fasteners including a pair of legs terminating in penetrating ends, and a backspan connecting the pair of legs, the backspan defining a longitudinal axis and having a twisted configuration such that a face of the backspan is rotated along a length of the backspan around the longitudinal axis, creating a spiral backspan configuration.

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.

13. A surgical fastener for use in a medical procedure, the surgical fastener including a pair of legs terminating in penetrating ends configured to pass through tissue, and a backspan connecting the pair of legs defining a longitudinal axis and having a twisted configuration, such that a face of the backspan is rotated along a length of the backspan around the longitudinal axis, creating a spiral backspan configuration, such that the backspan defines a non-uniform tissue contacting surface.

14. A surgical fastener applying apparatus comprising:
-
a handle portion; an elongate body portion extending distally from the handle portion; and a tool assembly supported adjacent a distal end of the elongate body portion, the tool assembly including; a first jaw including an anvil assembly; and a second jaw pivotally coupled to the first jaw such that the tool assembly is repositionable to clamp tissue between the first jaw and the second jaw, the second jaw including a cartridge assembly having a plurality of surgical fasteners disposed within the cartridge assembly, each surgical fastener in the plurality of surgical fasteners including a pair of legs terminating in penetrating ends, and a backspan connecting the pair of legs having a twisted configuration, such that a face of the backspan is rotated along a length of the backspan around a longitudinal axis of the backspan, creating a spiral backspan configuration, such that the backspan defines a non-linear tissue contacting surface. - View Dependent Claims (15, 16, 17)
