1. A surgical stapling device, comprising:

  • an anvil;

    a channel;

    a blocking surface coupled with said channel;

    a coupling member;

    a lockout spring; and

    a replaceable staple cartridge, comprising;

    a cartridge body;

    a proximal end positionable adjacent said coupling member;

    a distal end opposite said proximal end;

    staples removably stored within said cartridge body; and

    a proximally-positioned sled including a surface configured to overcome said lockout spring, wherein said lockout spring biases said blocking surface and said coupling member into an interference state in the absence of said surface of said proximally-positioned sled of the replaceable staple cartridge, and wherein the presence of said proximally-positioned sled counteracts said lockout spring to remove said interference between said blocking surface and said coupling member.
