Claim 18:
19. An adjunct configured for use with an end effector of a surgical stapler, comprising:
(a) a lattice structure comprising a first material; and
(b) at least one rail coupled to the lattice structure and comprising a second material different from the first material, wherein the at least one rail is configured to releasably attach the lattice structure to a stapling surface of the end effector,
wherein the lattice structure is configured to contact tissue clamped by the end effector during closure thereof,
wherein the lattice structure is further configured to be pierced and captured by staples ejected from the end effector into the clamped tissue and thereby reinforce the engagement between the ejected staples and the clamped tissue,
wherein at least a portion of the at least one rail is resiliently biased transversely inwardly relative to a longitudinal axis of the at least one rail,
wherein the at least one rail is configured to release the lattice structure from the stapling surface in response to ejection of the staples from the end effector while the end effector is closed.
