1. A buttress assembly configured for use with an end effector of a surgical stapler, comprising:
(a) a buttress body; and
(b) an adhesive layer disposed over the buttress body, wherein the adhesive layer includes a pressure sensitive adhesive having an embedded medicant, wherein the adhesive layer is configured to releasably adhere to one of an anvil or a stapling assembly of the end effector in response to closure of the end effector on the buttress assembly,
wherein the buttress body is configured to contact tissue clamped by the end effector during closure thereof,
wherein the buttress body is further configured to be pierced and captured by staples ejected from the stapling assembly into the clamped tissue and thereby reinforce the engagement between the ejected staples with the clamped tissue,
wherein the embedded medicant is configured to affect a physiological response in the clamped tissue.
