Abstract

A staple cartridge is disclosed. The staple cartridge comprises a staple cartridge body comprising a first side, a second side, and an elongated slot comprising a first lateral side and a second lateral side. The staple cartridge body further comprises, one, a deck having elevationally offset first and second portions, and, two, a plurality of staple cavities. The staple cartridge further comprises a plurality of staples comprising, one, a first row of staples supported a first forming distance from an anvil and formed against the anvil to a first deformed height and, two, a second row of staples supported a second forming distance from the anvil and formed against the anvil to a second deformed height, wherein the second deformed height is different than the first deformed height, and wherein the second forming distance is different than the first forming distance.

Claims

1. A staple cartridge, comprising:

a staple cartridge body, comprising;

a first side;

a second side;

an elongated slot comprising a first lateral side and a second lateral side;

a deck, said deck comprising a first portion and a second portion, wherein said first portion is elevationally offset from said second portion; and

a plurality of staple cavities; and

a plurality of staples, comprising;

a first row of staples, wherein the staples in said first row of staples are supported a first forming distance from an anvil and formed against the anvil to a first deformed height; and

a second row of staples, wherein the staples in said second row of staples are supported a second forming distance from the anvil and formed against the anvil to a second deformed height, wherein said second deformed height is different than said first deformed height, and wherein said second forming distance is different than said first forming distance.

2. A staple cartridge for use with a surgical instrument assembly including an anvil, said staple cartridge comprising:

a staple cartridge body, comprising;

a first side;

a second side;

an elongated slot; and

a deck, wherein said deck comprises a central portion and a lateral portion, and wherein said central portion is offset from said lateral portion, and wherein said deck comprises a plurality of staple cavities; and

a plurality of staples positioned within said staple cavities, wherein said plurality of staples comprises;

a first row of staples, wherein said first row of staples comprises a plurality of first staples, wherein said first staples are supported a first distance from a datum, and wherein said first staples are formed against the anvil to a first deformed height; and

a second row of staples, wherein said second row of staples comprises a plurality of second staples, wherein said second row of staples are supported a second distance from the datum, wherein said second distance is different than said first distance, wherein said second staples are formed against the anvil to a second deformed height, and wherein said second deformed height is different that than said first deformed height.

3. An end effector for use with a surgical instrument, said end effector comprising:

an anvil; and

a staple cartridge, comprising;

a cartridge body, comprising;

a first side;

a second side;
