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.

23. A staple cartridge 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 cartridge layer arrangement, comprising; a first film layer; a first fibrous scaffold comprised of absorbable polymer strands; and an absorbable adhesive releasably holding said first film layer to said deck; and an anvil layer arrangement, comprising; a second film layer; a second fibrous scaffold comprised of absorbable polymer strands; and an absorbable adhesive releasably holding said second film layer to said anvil, wherein said staples are configured to implant said cartridge layer arrangement and said anvil layer arrangement against the tissue when said staples are ejected from said staple cavities, wherein said first fibrous scaffold and said second fibrous scaffold comprise a fibrous tissue interface when implanted against the tissue, and wherein said fibrous tissue interface is bounded by said first film layer and said second film layer. - View Dependent Claims (24, 25)
