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 and integrally coupled with the buttress body, wherein the adhesive layer includes a pressure sensitive adhesive arranged along a length of the buttress body in a proximal arrangement and in a distal arrangement different from the proximal arrangement, wherein the adhesive layer is configured to releasably adhere to one of an anvil or a staple cartridge 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 staple cartridge into the clamped tissue and thereby reinforce the engagement between the ejected staples with the clamped tissue.
