Abstract

A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.

Claims

1-18. -18. (canceled)

19. A stapling assembly, comprising:

an end effector movable from an open configuration to a closed configuration to capture tissue, wherein said end effector comprises;

an anvil; and

a staple cartridge, comprising;

a first tissue-contact surface;

a second tissue-contact surface stepped up from said first tissue-contact surface;

an annular row of staple cavities; and

a plurality of staples removable stored in said cavities, wherein said staples are deployable from said cavities into contact with said anvil in said closed configuration, wherein said anvil is configured to transition said staples from an unformed configuration to a formed configuration, and wherein each said staple comprises;

a crown;

a first staple leg extending from said crown; and

a second staple leg extending from said crown, wherein said first staple leg and said second staple leg define a plane intersecting said crown in said unformed configuration, wherein said first staple leg is bent toward a first side of said plane in said formed configuration, and wherein said second staple leg is bent toward a second side of said plane opposite said first side in said formed configuration.

20. A staple cartridge for use with a stapling assembly that includes an anvil movable toward said staple cartridge to capture tissue therebetween in a closed configuration, said staple cartridge comprising:

a deck, comprising;

a first deck surface; and

a second deck surface closer to the anvil than said first deck surface when the anvil is in the closed configuration;

an annular row of staple cavities; and

staples removably stored in said cavities, wherein said staples are deployable from said cavities into contact with the anvil when the anvil is in the closed configuration, wherein the anvil is configured to transition said staples from an unformed configuration to a formed configuration, and wherein each said staple comprises;

a crown;

a first deformable member extending from said crown; and

a second deformable member extending from said crown, wherein said first deformable member and said second deformable member define a plane intersecting said crown in said unformed configuration, wherein said first deformable member is deformed toward a first side of said plane in said formed configuration, and wherein said second deformable member is deformed toward a second side of said plane opposite said first side in said formed configuration.

21. A stapler, comprising:

an end effector movable from an open configuration to a closed configuration to capture tissue, wherein said end effector comprises;

a curved anvil; and

a curved staple cartridge, comprising;

a first deck surface positioned at a first distance from said curved anvil when said end effector is in said closed configuration;

a second deck surface positioned a second distance from said curved anvil when said end effector is in said closed configuration, wherein said first distance is different that said second distance; and

a staple deployable through an opening in said first deck surface, wherein said staple is configured to be transitioned by said curved anvil from an unformed configuration to a formed configuration, and wherein said staple comprises;

a crown, comprising;

 

a first side; and

 

a second side;

a first deformable member extending from said crown; and

a second deformable member extending from said crown, wherein said first deformable member is deformed toward a first side of said crown in said formed configuration, and wherein said second deformable member is deformed toward a second side of said crown opposite said first side in said formed configuration.
