Abstract
A retainer for use with a staple cartridge that is configured for use with a stapling device is disclosed. The retainer comprises a retainer body that is configured to be removably coupled to the staple cartridge to form a cartridge assembly. The retainer further comprises an authentication key that is oriented in a first configuration to defeat a lockout in the surgical stapling device when the cartridge assembly is seated in the surgical stapling device. The authentication key is movable to a second configuration after the cartridge assembly is removed from the stapling device such that the authentication key is unable to return to the first configuration.
