Abstract
A piece of buttress material and an end-effector of a surgical instrument including features which can aid a surgeon in properly and quickly attaching the piece of buttress material to the end-effector. In various embodiments, a piece of buttress material can include retention features which can be engaged with portions of an end-effector to releasably retain the piece of buttress material to at least a portion of the end-effector. Similarly, an end-effector can include features configured to engage portions of a piece of buttress material to releasably retain the piece of buttress material to the end-effector. In at least one embodiment, more than one piece of buttress material can be releasably retained to an end-effector.

17. A surgical instrument system, comprising:
-
an end effector, comprising; a first jaw; a second jaw, wherein said second jaw is rotatable relative to said first jaw; a staple cartridge, comprising; a deck comprising a first step and a second step; a first longitudinal row of staple cavities defined in said first step; a second longitudinal row of staple cavities defined in said second step; and staples removably stored in said staple cavities; an anvil, comprising; a tissue compression surface; and forming pockets configured to deform said staples; an applicator assembly, comprising; a support insertable between said deck and said tissue compression surface, wherein said support comprises a first support surface and a second support surface; a first implantable layer releasably attached to said first support surface, wherein said first implantable layer comprises a first outwardly-facing surface configured to engage said first step and said second step of said deck; a flowable polymer adhesive on said first outwardly-facing surface; a second implantable layer releasably attached to said second support surface, wherein said second implantable layer comprises a second outwardly-facing surface configured to engage said tissue compression surface of said anvil; a flowable polymer adhesive on said second outwardly-facing surface, wherein each said flowable polymer adhesive is comprised of a copolymer composed of polycaprolactone in the range of from about 65 mole percent to about 35 mole percent; and removable packaging which covers said first implantable layer and said second implantable layer and inhibits the inadvertent attachment of said flowable polymer adhesive. - View Dependent Claims (18, 19, 20, 21, 22)
