1. An adjunct configured for use with an end effector of a surgical stapler, comprising:
(a) a plurality of resiliently compressible protrusions interconnected with each other;
(b) a tissue-engaging face configured to contact tissue clamped by the end effector during closure thereof; and
(c) a stapler-engaging face configured to be releasably secured to a stapling surface of the end effector,
wherein each resiliently compressible protrusion of the plurality of resiliently compressible protrusions includes a hollow interior and an open end at one of the tissue-engaging or stapler-engaging faces, wherein the hollow interior expands radially outwardly relative to a vertical central axis of the respective compressible protrusion toward the open end,
wherein each resiliently compressible protrusion of the plurality of resiliently compressible protrusions is configured to be captured and compressed by a corresponding staple ejected from the end effector into the clamped tissue and thereby reinforce an engagement between the ejected staples and the clamped tissue.
