Abstract

A staple cartridge is disclosed comprising a proximal end, a distal end, a cartridge deck, and a sloped nose. The cartridge deck comprises a first tissue-supporting surface extending distally to a first distal edge, a plurality of staple cavities defined in the first tissue-supporting surface, a sloped wall extending from the first tissue-supporting surface, a longitudinal slot defined in the first tissue-supporting surface and at least a portion of the sloped wall, and a second tissue-supporting surface. The sloped wall slopes from the first distal edge to a second distal edge. The sloped wall comprises a distal blocking surface. The longitudinal slot extends from the proximal end to the distal blocking surface. The second tissue-supporting surface extends from the second distal edge. The second tissue-supporting surface does not comprise staple cavities defined therein. The sloped nose is positioned distal to the second tissue-supporting surface.

a plurality of staple cavities defined within said planar proximal portion;
a planar distal portion comprising a second tissue-supporting surface extending along a second plane, wherein said planar distal portion extends from said first lateral edge to said second lateral edge, wherein said planar distal portion is positioned distal to said longitudinal slot, wherein said planar distal portion does not comprise staple cavities defined therein, wherein said first tissue-supporting surface and said second tissue-supporting surface are longitudinally aligned, wherein said end effector assembly is configurable in an open configuration and a closed configuration, wherein a first tissue gap distance is defined between said first tissue-supporting surface and said anvil based on said end effector assembly being in said closed configuration, wherein a second tissue gap distance is defined between said second tissue-supporting surface and said anvil based on said end effector assembly being in said closed configuration, and wherein said first tissue gap distance is different than said second tissue gap distance;
a sloped wall extending between said planar proximal portion and said planar distal portion, wherein said sloped wall slopes from said distal edge, and wherein said longitudinal slot extends distally past said distal edge through at least a portion of said sloped wall to said distal blocking surface;
and
a sloped nose positioned distal to said distal planar portion.
