Abstract
An apparatus for joining two hollow organ sections with an annular array of surgical staples includes a staple cartridge component, an anvil component, a buttress component and a fastening member. The staple cartridge component includes a plurality of surgical staples arranged in an annular array. The anvil component is movable relative to the staple cartridge component between spaced apart and approximated positions to adjustably clamp the organ sections between the staple cartridge and anvil components. The buttress components are configured and dimensioned to be positioned on a distal surface of the staple cartridge component and the proximal surface of the anvil component. In particular, the buttress component includes a buttress member and a plurality of circumferentially arranged tabs extending proximally from the buttress member. The fastening member is configured and dimensioned to engage the plurality of circumferentially arranged tabs to securely position the buttress component on the staple cartridge component.
