Abstract
A staple cartridge assembly includes, one, a plurality of staples movable between unfired positions and fired positions and, two, a layer, such as a tissue thickness compensator and/or a buttress material, for example, wherein the staples are configured to at least partially capture the layer when the staples are moved between the unfired positions and the fired positions. The layer can include a cushioning member at least partially extending around a peripheral portion of the tissue thickness compensator. The layer can include features which create a flexible transition between the tissue supported by the layer and the staples and the unsupported tissue.
Claims17
A staple cartridge assembly, comprising:
- a cartridge body, comprising:
- a deck;
- and
- a plurality of staples movable between unfired positions and fired positions;
- and
- an implantable layer, wherein said staples are configured to at least partially capture said implantable layer when said staples are moved between said unfired positions and said fired positions, said implantable layer comprising:
- an implantable first portion, wherein said implantable first portion defines a non-hollow central core of said implantable layer;
- and
- an implantable second portion at least partially surrounding said implantable first portion, wherein said implantable second portion defines a continuous outer perimeter of said implantable layer, wherein said implantable second portion is more flexible than said implantable first portion, and wherein said implantable second portion comprises a plurality of slits,
- wherein said staples, in said fired positions, form a staple line along at least a portion of said captured implantable layer, and wherein each said slit is configured to be in a plane crossing said staple line between said staples.
