Abstract

A retainer for assembling tissue thickness compensators to a surgical stapler can comprise a grip, a first surface for supporting a first tissue thickness compensator, a second surface for supporting a second tissue thickness compensator, and clips for aligning and attaching the retainer to the surgical stapler. The clips may align and attach the retainer to a staple cartridge of the surgical instrument. The clips may align the retainer with an anvil of the surgical instrument. An insertion tool may be used in combination with the retainer to insert the retainer into the surgical stapler and to push the tissue thickness compensators against the anvil and/or the staple cartridge of the surgical instrument.

Claims

1-22. -22. (canceled)

23. A stapling system for stapling tissue, comprising:

a cartridge, comprising;

a deck;

staple cavities defined in said deck; and

staples removably stored in said staple cavities;

an anvil configured to deform said staples;

a buttress, comprising;

a first layer comprised of a first absorbable polymer;

a first medicament embedded in said first layer;

a second layer comprised of a second absorbable polymer which is different than said first absorbable polymer, wherein said second layer co-operates with said first layer; and

a second medicament embedded in said second layer which is different than said first medicament, wherein said second medicament co-operates with said first medicament.

24. The stapling system of claim 23, wherein said first medicament is released at a first rate, and wherein said second medicament is released at a second rate which is different than said first rate.

25. A stapling system for stapling tissue, comprising:

a cartridge, comprising;

a deck;

staple cavities defined in said deck; and

staples removably stored in said staple cavities; and

a buttress, comprising;

a first layer comprising a first absorbable polymer;

a first medicament embedded in said first layer;

a second layer comprising a second absorbable polymer which is different than said first absorbable polymer, wherein said second layer supports said first layer; and

a second medicament embedded in said second layer which is different than said first medicament, wherein said second medicament affects a healing result with said first medicament.

26. The stapling system of claim 25, wherein said first medicament is released at a first rate, and wherein said second medicament is released at a second rate which is different than said first rate.

27. The stapling system of claim 25, further comprising an anvil configured to deform said staples.

28. A fastening system for fastening tissue, comprising:

a cartridge, comprising;

a cartridge body; and

fasteners removably stored in said cartridge body; and

an implant, comprising;

a first portion comprising a first absorbable polymer;

a first medicament releasably stored in said first portion;

a second portion comprising a second absorbable polymer which is different than said first absorbable polymer; and

a second medicament releasably stored in said second portion which is different than said first medicament, wherein the release of said second medicament and the release of said first medicament co-operatively produce a healing result.

29. The fastening system of claim 28, wherein said first medicament is released at a first rate, and wherein said second medicament is released at a second rate which is different than said first rate.

30. The fastening system of claim 28, further comprising an anvil configured to deform said fasteners.
