Claims24
A staple cartridge assembly, comprising:
- a cartridge body comprising a deck and a plurality of staple cavities defined in said deck;
- a plurality of staples removably stored in said staple cavities;
- and
- an implantable layer positioned over said staple cavities, wherein said implantable layer comprises:
- structural fibers weaved into a top surface, a bottom surface, and pillar walls extending between said top surface and said bottom surface, wherein said pillar walls comprise:
- a first pillar wall;
- a second pillar wall;
- and
- an intermediate pillar wall positioned between said first pillar wall and said second pillar wall;
- and
- reinforcement fibers interwoven within said pillar walls.
