Abstract

A staple cartridge comprising a deformable authentication key that is movable between a first state and a second state is disclosed. The authentication key is configured to operably engage a lockout of a surgical stapling device when the staple cartridge is inserted into the surgical stapling device in an initial insertion position. When the cartridge is seated in a final position within the device, the authentication key is deformed from the first state to the second state and moves the lockout from a locked position to an unlocked position.
