Implantable adjunct systems for determining adjunct skew
First Claim
1. A staple cartridge system for use with a surgical stapling instrument, said staple cartridge system comprising:
- 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.

Abstract
An implantable adjunct for use with a surgical stapling instrument is provided. The implantable adjunct comprises a mechanism for allowing a clinician to determine the degree of skew, if any, that the adjunct may experience when implanted into a subject with a surgical stapling instrument. The implantable adjunct comprises one or more reference systems configured to be compared to the staples, the edges of the adjunct, and/or any other adjunct elements by a clinician once the adjunct has been implanted into the subject. The one or more reference systems comprise references that define one or more zones of the adjunct. A clinician can visually determine what zone, or zones, of the adjunct the staples have satisfactorily, and/or unsatisfactorily, purchased the adjunct.

11. A staple cartridge system for use with a surgical stapling instrument, said staple cartridge system comprising:
-
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 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 said reference system comprises a longitudinal reference positioned such that the clinician can determine an amount of longitudinal skew of said implantable adjunct by comparing said staples to said longitudinal reference when said staples are in said fired position, wherein said plurality of staple cavities further comprises at least one distal-most cavity and at least one proximal-most cavity, wherein said at least one distal-most cavity defines a distal purchase datum and said at least one proximal-most cavity defines a proximal purchase datum, and wherein said distal purchase datum and said proximal purchase datum are positioned in said first zone when said staples are in said unfired position.

12. A staple cartridge system for use with a surgical stapling instrument, said staple cartridge system comprising:
-
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 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, wherein said reference system comprises dye applied on said implantable adjunct, and wherein said first zone comprises a first color and said second zone comprises a second color.

13. A staple cartridge system for use with a surgical stapling instrument, said staple cartridge system comprising:
-
a cartridge body, comprising; a longitudinal slot configured to receive a cutting member; a deck; and a plurality of staple cavities arranged in a plurality of longitudinal rows; a plurality of staples removably stored within said staple cavities, wherein said staples are configured to be ejected from said staple cavities into a fired position; and an implantable adjunct positioned above 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 for determining the alignment of said staples relative to said implantable adjunct once said staples are in said fired position, and wherein said reference is defined on said implantable adjunct at a location which allows a clinician to assess whether said staples are too close to an edge of said implantable adjunct. - View Dependent Claims (14, 15, 16)
