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. An end effector for stapling the tissue of a patient, comprising:
-
a staple cartridge body, comprising; a proximal end; a distal end; a deck configured to support the tissue; a first lateral side; a second lateral side; staple cavities; and staples removably stored in said staple cavities; an anvil configured to deform said staples; a firing member movable toward said distal end to eject said staples from said staple cavities during a firing stroke; buttress material positioned over said deck, wherein said buttress material comprises an aperture defined therein; a first release string engaged with said buttress material, wherein said first release string is releasable from said buttress material prior to the completion of said firing stroke; a second release string engaged with said buttress material; and an engaging projection received within said aperture which is configured to limit lateral displacement of said buttress material between said first release string and said second release string. - View Dependent Claims (18, 19, 20, 21, 22)
