  • Patent number: 9775618
    Abstract: A surgical stapling instrument is provided having systems for securing buttress material to the anvil and staple containing cartridge associated with the surgical instrument. The system includes a retainer configured to engage the anvil or the staple containing cartridge and capture the buttress material between the retainer and the anvil or staple containing cartridge. The disclose retainer engages the anvil or staple containing cartridge in snap fit or friction fit fashion. The buttress material includes a circumferential perforation line enabling the center of the buttress material to be stapled to tissue while the remainder of the buttress material remains with the anvil or staple containing cartridge.
