The buttress includes a buttress body portion supporting a toe strap that extends distally from the buttress body portion. The release strap is releasably coupled to the toe strap of the buttress. The release strap is movable relative to the buttress to separate the release strap from the buttress. ## Claims ### Claim 1 An end effector having a proximal end for selective connection to a distal end of an elongated body portion of a surgical stapling apparatus, the end effector comprising: a cartridge assembly; and an anvil assembly movably coupled to the cartridge assembly and supporting a surgical buttress assembly, the surgical buttress assembly including: a buttress; a folded portion coupled to the buttress; and a release strap that is releasably coupled to the buttress and extending proximally from the proximal end of the end effector, the release strap integrally formed with the folded portion and being of sufficient length to be disposed outside of a patient's body when the end effector is fully inserted within the patient's body. ### Claim 2 (depends on 1) The end effector of claim 1, wherein the folded portion is separable from the buttress by perforations. ### Claim 3 (depends on 1) The end effector of claim 1, wherein the release strap includes a band, a cord, a rope, a strap, a suture, or combinations thereof. ### Claim 4 (depends on 1) The end effector of claim 1, wherein the folded portion includes a first section and a second section, the first section extending along a first side of the buttress, the second section extending along a second side of the buttress. ### Claim 5 (depends on 4) The end effector of claim 4, wherein the first and second sections are configured to couple directly to one another when the buttress is secured to the end effector. ### Claim 6 (depends on 5) The end effector of claim 5, wherein the buttress and the folded portion form a tubular body when the first and second sections are coupled to one another. ### Claim 7 (depends on 6) The end effector of claim 6, wherein the first and second sections are welded together. ### Claim 8 A surgical stapling apparatus, comprising: a housing; and an elongated tubular body portion extending from the housing and supporting an end effector, the end effector including: a cartridge assembly supporting fasteners; and an anvil configured to form the fasteners of the cartridge assembly and supporting a surgical buttress assembly, the surgical buttress assembly including: a buttress; a folded portion coupled to the buttress; and a release strap that is releasably coupled to the buttress and integrally formed with the folded portion, the release strap extending proximally from the end effector and along the elongated tubular body portion for accessibility of a proximal end portion of the release strap outside a patient's body when the end effector is inserted in the patient's body. ### Claim 9 (depends on 8) The surgical stapling apparatus of claim 8, wherein the folded portion is separable from the buttress by perforations. ### Claim 10 (depends on 8) The surgical stapling apparatus of claim 8, wherein the release strap includes a band, a cord, a rope, a strap, a suture, or combinations thereof. ### Claim 11 (depends on 8) The surgical stapling apparatus of claim 8, wherein the folded portion includes a first section and a second section, the first section extending along a first side of the buttress, the second section extending along a second side of the buttress. ### Claim 12 (depends on 11) The surgical stapling apparatus of claim 11, wherein the first and second sections are configured to couple directly to one another when the buttress is secured to the end effector. ### Claim 13 (depends on 12) The surgical stapling apparatus of claim 12, wherein the buttress and the folded portion form a tubular body when the first and second sections are coupled to one another. ### Claim 14 (depends on 13) The end effector of claim 13, wherein the first and second sections are welded together.
