1. A surgical kit comprising:
a surgical stapling device including:
a tool assembly including first and second jaw members that are transitionable between open and closed configurations, the first jaw member supporting a staple cartridge that includes a retention assembly and defines proximal and distal slots, the retention assembly including:
a proximal hook disposed within the proximal slot of the staple cartridge; and
a distal hook disposed within the distal slot of the staple cartridge;
a buttress material including an elongate body having proximal and distal portions, proximal protrusions extending laterally outwards from the proximal portion of the elongate body, and distal protrusions extending laterally outwards from the distal portion of the elongate body, the proximal protrusions defining respective proximal bores, the distal protrusions defining respective distal bores, the buttress material defining a proximal slot interposed between the proximal bores and a distal slot interposed between the distal bores; and
a loading assembly including:
proximal wings that are laterally spaced apart, each of the proximal wings including a proximal peg configured to be received through a corresponding one of the proximal bores of the buttress material;
distal wings that are laterally spaced apart, each of the distal wings including a distal peg configured to be received through a corresponding one of the distal bores of the buttress material;
a proximal cup configured to receive a portion of the proximal hook of the staple cartridge and engage a first portion of the buttress material to position the first portion of the buttress material in the proximal slot of the staple cartridge to be releasably secured to the proximal hook; and
a distal cup configured to receive a portion of the distal hook of the staple cartridge and engage a second portion of the buttress material to position the second portion of the buttress material in the distal slot of the staple cartridge to be releasably secured to the distal hook.
