  • a cartridge body, comprising;

    a longitudinal slot configured to receive a cutting member;

    a deck; and

    a plurality of staple cavities, comprising;

    an outer row of staple cavities; and

    an inner row of staple cavities positioned adjacent said longitudinal slot; and

    a plurality of staples removably stored within said staple cavities, wherein said staples are configured to be ejected from said staple cavities from an unfired position to a fired position; and

    an implantable adjunct positioned adjacent said deck, wherein said implantable adjunct is configured to be implanted into a subject when said staples are ejected from said staple cavities into said fired position, wherein said implantable adjunct comprises a reference system that defines a first zone and a second zone, wherein said first zone comprises a first perimeter demarcation within the perimeter of said first zone, wherein said second zone comprises a second perimeter demarcation within the perimeter of said second zone, wherein said reference system is configured to assist a clinician in determining the position of said staples relative to said first zone and said second zone when said staples are in said fired position, wherein the positioning of said staples in said first zone provides a low-risk indication in terms of tissue ligation and the positioning of said staples in said second zone provides a high-risk indication in terms of tissue ligation, and wherein said first perimeter demarcation and said second perimeter demarcation are present after said implantable adjunct has been compressed against tissue.
