Claims13
A compensator attachable to an anvil of a fastening instrument, wherein the anvil includes a forming surface, and wherein said compensator comprises:
- a first layer comprised of first fibers and second fibers, wherein said first fibers are comprised of a first material and said second fibers are comprised of a second material, wherein said first material is different than said second material, and wherein said first fibers and said second fibers are present within said first layer according to a first ratio by quantity;
- a second layer comprised of said first fibers and said second fibers, wherein said first fibers and said second fibers are present within said second layer according to a second ratio by quantity, and wherein said first ratio by quantity is different than said second ratio by quantity;
- and
- an attachment portion configured to be attached to the anvil.
A staple cartridge, comprising:
- a cartridge body;
- staples removably stored in said cartridge body;
- and
- a compensator, comprising:
- a first layer comprised of first fibers and second fibers, wherein said first fibers are comprised of a first material and said second fibers are comprised of a second material, wherein said first material is different than said second material, and wherein said first fibers and said second fibers are present within said first layer according to a first ratio by quantity;
- and
- a second layer comprised of said first fibers and said second fibers, wherein said first fibers and said second fibers are present within said second layer according to a second ratio by quantity, and wherein said first ratio by quantity is different than said second ratio by quantity.
