Fastener cartridge comprising a tissue thickness compensator and a gap setting element
First Claim
1. A fastener cartridge for use with a fastening instrument including an anvil and a longitudinally movable firing member, said fastener cartridge comprising:
- a cartridge body, comprising;
a deck; and
fastener cavities;
fasteners removably stored in said cartridge body in an unfired position, wherein said fasteners are movable into a fired position;
a compressible tissue thickness compensator positioned on said deck, wherein said fasteners are configured to capture a portion of said tissue thickness compensator therein when said fasteners are moved from said unfired position to said fired position; and
a flexible gap-setting element extending from said cartridge body, wherein said gap-setting element establishes a relative position between the anvil and said tissue thickness compensator, and wherein the firing member contacts said gap-setting element to cause said gap-setting element to flex toward said deck of said cartridge body when the firing member approaches a distal end of said cartridge body.

Abstract
A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be arranged in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened. The fastener cartridge can further comprise a gap setting element which can be configured to control the distance between the anvil, the support portion, and/or the tissue thickness compensator.

9. An end effector for use with a surgical instrument, said end effector comprising:
-
an anvil; a longitudinally movable cutting member; a staple cartridge, comprising; a cartridge body comprising a stepped deck; a longitudinal row of first staples; a longitudinal row of second staples; and a longitudinal array of staple drivers configured to deform said first staples to a first formed height and said second staples to a second formed height, wherein said first formed height is different than said second formed height; an implantable layer positioned on said stepped deck, wherein said first staples and said second staples are configured to capture a portion of said implantable layer therein when said first staples and said second staples are formed against said anvil; and a gap-setting element extending over said stepped deck of said cartridge body, wherein said gap-setting element establishes a relative position between said anvil and said implantable layer, and wherein said cutting member contacts said gap-setting element to displace said gap-setting element relative to said stepped deck of said cartridge body when said cutting member approaches a distal end of said cartridge body. - View Dependent Claims (10, 11, 12)

13. A surgical stapling instrument comprising:
-
an anvil; a distal end; a firing member movable toward said distal end during a staple firing stroke; a cutting surface; a staple cartridge, comprising; a cartridge body, comprising; a stepped deck; and staple cavities; and staples removably stored in said staple cavities in an unfired position, wherein said staples are movable into a fired position; an implantable layer positioned on said stepped deck, wherein said staples are configured to capture a portion of said implantable layer therein when said staples are moved from said unfired position to said fired position; and a flexible element positioned intermediate said anvil and said cartridge body, wherein said flexible element and said firing member establish a relative position between said anvil and said implantable layer during said staple firing stroke, and wherein said cutting surface contacts said flexible element to cause said flexible element to deflect when said firing member approaches said distal end of said cartridge body. - View Dependent Claims (14, 15, 16, 17, 18)
