Patent number: 11801052Abstract: A loading assembly includes a cartridge having a cartridge body with rows of staple pockets. A carrier includes a platform adapted to releasably retain the cartridge. A shell is laterally spaced from the platform and flexibly coupled thereto. The arm extends through the shell at an acute angle and the shell has a passage that is configured to receive a jaw member of a surgical stapling instrument therethrough. A surgical buttress has a distal region with a first orifice and a cutout and a proximal region with a second orifice. The first orifice is attachable to a peg located in a distal region of the shell and the second orifice is attachable to a post located in a distal region of the cartridge such that a portion of the surgical buttress extends through the passage of the shell. The cutout is configured to receive an arm of the platform therethrough.Type: GrantFiled: August 30, 2021Date of Patent: October 31, 2023Assignee: Covidien LPInventors: Jacob C. Baril, Roanit A. Fernandes, Thomas Casasanta, Jr, Christopher M. Meehan, Saumya Banerjee, Justin J. Thomas
