Fastener cartridge comprising a tissue thickness compensator including openings therein
First Claim
1. A fastener cartridge assembly, comprising:
- a cartridge body comprising a fastener cavity;
a tissue thickness compensator releasably secured relative to said cartridge body, wherein said tissue thickness compensator comprises;
a first aperture extending along a first predefined trajectory; and
a second aperture extending along a second predefined trajectory; and
a fastener removably positioned in said fastener cavity, wherein said fastener comprises;
a first leg aligned with said first aperture and moveable along said first predefined trajectory, wherein a clearance is defined between said first leg and said first aperture when said first leg moves along said first predefined trajectory; and
a second leg aligned with said second aperture and moveable along said second predefined trajectory.

Abstract
A fastener cartridge assembly. The fastener cartridge assembly can comprise a cartridge body, a tissue thickness compensator releasably secured relative to the cartridge body, and a fastener removably positioned in a staple cavity of the cartridge body. The tissue thickness compensator can comprise a first clearance aperture extending along a first predefined trajectory and a second clearance aperture extending along a second predefined trajectory. The fastener can comprise a first leg aligned with the first clearance aperture and moveable along the first predefined trajectory, a second leg aligned with the second clearance aperture and moveable along the second predefined trajectory. The first and second predefined trajectories can be parallel.
