Patent attributes
An adjunct material for use with an end effector for a surgical instrument is provided that has different types of features for mating with the end effector. The adjunct is configured to be releasably retained on a jaw, such as a cartridge or anvil, using a plurality of female features formed thereon. Each female feature is configured to encompass a corresponding at least one of male features formed on the jaw in a clearance fit such that the adjunct is able to move with respect to the jaw at least in a first plane parallel to the tissue-facing surface. The male and female features mate such that the adjunct is not retained in a second plane that is perpendicular to the first plane. The adjunct also includes at least one attachment feature configured to releasably retain the adjunct on the jaw.
