Abstract

A staple cartridge that comprises a catridge body, a plurality of staples removably positioned in the cartridge body, and a compressible portion is disclosed. The compressible portion comprises a first portion, a second portion, and a structurally-deficient portion supporting the second portion. The structurally-deficient portion is configured to permit a collapsing motion of the second portion relative to the first portion. The structurally-deficient portion comprises a plurality of cell walls.
