Abstract
A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.
