Abstract: Various embodiments of a frame for attaching an adjunct to an end effector of a surgical device are provided. In one embodiment, the end effector can include upper and lower jaws, and the frame can include features for releasably engaging one or the jaws. The frame can also include retaining features for coupling an adjunct to a tissue-facing surface of the frame, thereby releasably coupling the adjunct material to the jaw of the end effector. In some implementations, the frame can include a plurality of retaining features that are configured to engage the adjunct material to create a tension in the adjunct material, which can further assist with securing the frame to the jaw. In other embodiments, a removable applicator member is provided for retaining at least one adjunct material and for aligning and coupling the adjunct material to a frame.

Abstract: An adjunct material for use with an end effector in a surgical instrument is provided that has at least one projection configured to mate with a corresponding recess formed in at least one jaw, such as a cartridge or anvil, of the end effector. The at least one projection can be one or more discrete projections or longitudinal projection(s) extending between distal and proximal ends of the adjunct material. An applicator member can be used to apply force to the adjunct material to thus cause the adjunct material to mate with the jaw of the end effector. The applicator member can be configured told the adjunct material and can be clamped between the jaws of the end effector to release the adjunct material onto the jaw. Also, an applicator member can be used to push portions of an adjunct material into corresponding recesses in a jaw.
