Cartridge holder for surgical staples and having ridges in peripheral walls for gripping tissue

A surgical stapling device comprising:

• an elongate body having a proximal portion and a distal portion;
• a tool assembly supported on the distal portion of the elongate body and defining a longitudinal axis, the tool assembly including an anvil assembly and a cartridge assembly, the anvil assembly having a distal end portion and a tissue engaging surface, the cartridge assembly having a distal end portion and including a cartridge channel and a staple cartridge, the staple cartridge having a distal end portion and a tissue contacting surface, the cartridge assembly is coupled to the anvil assembly such that the tool assembly is movable between an open position in which the distal end portions of the anvil and cartridge assemblies are spaced from each other and a clamped position in which the tissue engaging surface of the anvil assembly and the tissue contacting surface of the staple cartridge are in juxtaposed alignment;
• the cartridge channel including a base wall and spaced side walls that define an elongated recess, the elongated recess receiving the staple cartridge, wherein each of the spaced side walls supports a plurality of ridges, each of the plurality of ridges spaced outwardly of the tissue contacting surface of the staple cartridge and including a tissue engagement portion that extends above an entirety of the tissue contacting surface of the staple cartridge in a direction towards the anvil assembly.
