Abstract: A surgical stapling device is described having a tool assembly including an anvil assembly and a staple cartridge having a series of staples which are supported and configured to be rotatably ejected from the staple cartridge into the anvil assembly to suture tissue. The manner in which the staples are supported and ejected from within the staple cartridge facilitates the use of a tool assembly of reduced diameter that includes staples capable of suturing thicker tissues than would normally be associated with tool assemblies with such a reduced diameter. A staple is also described that can be ejected from the surgical stapling device. In embodiments, the staple includes three legs of different lengths. Each of the legs is configured to provide a different degree of compression when applied to tissue. In addition, each of the staple legs has a D-shaped configuration when deformed.
