1. An end effector for a medical device, the end effector comprising:
an anvil that includes a first end, a second end, and a first face;
a cartridge that is operably configured to house a plurality of staples and that includes a first end, a second end, and a second face, wherein the first end of the anvil and the first end of the cartridge define a distal end of the end effector and the second end of the anvil and the second end of the cartridge define a proximal end of the end effector, the first end of the cartridge being movably coupled to the first end of the anvil, the anvil being movable relative to the cartridge to define a first gap between the first face and the second face at the first end of the anvil and the first end of the cartridge that is differently sized from a second gap between the first face and the second face at the second end of the anvil and the second end of the cartridge; and
a tensioning mechanism comprising a pin and a flexible member, the flexible member routed around the pin and operably coupled to the anvil and the cartridge.
