Abstract
An adjunct configured for use with an end effector of a surgical stapler includes a plurality of resiliently compressible elements interconnected with each other. The adjunct also includes a tissue-engaging face configured to contact tissue clamped by the end effector during closure thereof, and a stapler-engaging face configured to be releasably secured to a stapling surface of the end effector. Each resiliently compressible element of the plurality of resiliently compressible elements includes a hollow interior and an open end at one of the tissue-engaging or stapler-engaging faces. The hollow interior expands outwardly toward the open end. Each resiliently compressible element of the plurality of resiliently compressible elements is configured to be captured and compressed by a corresponding staple ejected from the end effector into the clamped tissue and thereby reinforce the engagement between the ejected staples and the clamped tissue.
