Tissue thickness compensator with tissue ingrowth mechanism

摘要

In a different embodiment, the compensator can be attached to a fastener anvil (22760). The compensator can have a support layer (24226) configured to be attached to the anvil and a scaffold (24222) attached to the support layer. In at least one embodiment, the scaffold may have a scaffold layer (24227) composed of a biocompatible material and a plurality of cavities, the layers and cavities being a preferred matrix for tissue and cell ingrowth. Can be defined.
