## 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.

## Claims

### Claim 1

a second jaw, wherein one of said first jaw and said second jaw is movable relative to the other of said first jaw and said second jaw;
an implantable layer configured to be installed onto said first jaw, wherein said implantable layer comprises:
a first side comprising an adhesive;
a second side opposite said first side;
a third outer lateral edge;
a fourth outer lateral edge, wherein a lateral layer width is defined between said third outer lateral edge and said fourth outer lateral edge, and wherein said lateral layer width is narrower than said lateral jaw width; and
an attachment zone between said third outer lateral edge and said fourth outer lateral edge; and
an applicator assembly comprising an applicator body, wherein said implantable layer is releasably attached to said applicator body within said attachment zone by a fastener in contact with said implantable layer within said attachment zone to selectively apply a holding force to said implantable layer within said attachment zone.

### Claim 2 (depends on 1)
