The first jaw member is moveable relative to the second jaw member. The first jaw member includes a contact surface, a first projection, and a catch. The catch includes first and second fingers distal of the first projection. The second finger is biased toward the contact surface. The buttress material defines a longitudinal axis. The buttress material is releasably secured to the first jaw member. The buttress material defines first, second, and third slots formed therein. The first projection of the first jaw member is received in the first slot of the buttress material. The first finger of the catch is received in the second slot of the buttress material. ## Claims ### Claim 1 An end effector of a surgical stapler, comprising: first and second jaw members, the first jaw member moveable relative to the second jaw member, the first jaw member including a contact surface, a first projection, and a catch, the catch including first and second fingers distal of the first projection, the second finger biased toward the contact surface; and a buttress material defining a longitudinal axis, the buttress material releasably secured to the first jaw member, the buttress material defining first, second, and third slots formed therein, the first projection of the first jaw member received in the first slot of the buttress material, the first finger of the catch received in the second slot of the buttress material. ### Claim 2 (depends on 1) The end effector according to claim 1, wherein the first and second fingers of the catch are formed of an elastic material. ### Claim 3 (depends on 1) The end effector according to claim 1, wherein the first and second fingers of the catch define an acute angle with respect to each other. ### Claim 4 (depends on 1) The end effector according to claim 1, wherein the second finger of the catch includes a head portion and a neck portion, the head portion defining a first width, the neck portion defining a second width smaller than the first width. ### Claim 5 (depends on 4) The end effector according to claim 4, wherein the head portion of the second finger may be configured to engage the contact surface of the first jaw member. ### Claim 6 (depends on 1) The end effector according to claim 1, wherein the first jaw member includes an anvil assembly. ### Claim 7 (depends on 1) The end effector according to claim 1, wherein the buttress material is transitionable between an unexpanded state and an expanded state. ### Claim 8 (depends on 1) The end effector according to claim 1, wherein the second and third slots of the buttress material are adjacent to each other. ### Claim 9 (depends on 1) The end effector according to claim 1, wherein the second slot of the buttress material is defined transverse to the longitudinal axis of the buttress material. ### Claim 10 (depends on 1) The end effector according to claim 1, wherein the third slot of the buttress material extends along a length of the longitudinal axis of the buttress material. ### Claim 11 (depends on 1) The end effector according to claim 1, wherein a proximal portion of the buttress material is tapered. ### Claim 12 An end effector of a surgical stapler, comprising: first and second jaw members, the first jaw member moveable relative to the second jaw member, the first jaw member including a contact surface and a catch having first and second fingers, the second finger biased toward the contact surface, the second jaw member including first and second projections, the second projection distal of the first projection; and a buttress material defining a longitudinal axis, the buttress material releasably secured with at least one of the first or second jaw members, the buttress material defining first, second, and third slots formed therein, the first projection of the second jaw member received in the first slot of the buttress material when the buttress material is secured with the second jaw member, the first finger of the catch received in the second slot of the buttress material when the buttress material is secured with the first jaw member, the second projection of the second jaw member received in the third slot of the buttress material when the buttress material is secured with the second jaw member. ### Claim 13 (depends on 12) The end effector according to claim 12, wherein the first and second fingers of the catch are formed of an elastic material. ### Claim 14 (depends on 12) The end effector according to claim 12, wherein the first and second fingers of the catch define an acute angle with respect to each other. ### Claim 15 (depends on 12) The end effector according to claim 12, wherein the second finger of the catch includes a head portion and a neck portion, the head portion defining a first width, the neck portion defining a second width smaller than the first width. ### Claim 16 (depends on 15) The end effector according to claim 15, wherein the head portion of the second finger is configured to engage the contact surface of the first jaw member. ### Claim 17 (depends on 12) The end effector according to claim 12, wherein the first jaw member includes an anvil assembly. ### Claim 18 (depends on 12) The end effector according to claim 12, wherein the buttress material is transitionable between an unexpanded state and an expanded state. ### Claim 19 (depends on 12) The end effector according to claim 12, wherein the second slot of the buttress material is defined transverse to the longitudinal axis of the buttress material. ### Claim 20 (depends on 12) The end effector according to claim 12, wherein the third slot of the buttress material is extends along a length of the longitudinal axis of the buttress material. ### Claim 21 A buttress material for use with a surgical stapling instrument, the buttress material comprising: an elongate body defining a longitudinal axis, the elongate body including proximal and distal portions, the proximal portion including a tapered portion, the proximal portion defining first and second proximal slots separated by a wall, the first and second proximal slots extending transverse to the longitudinal axis, the distal portion defining first and second distal slots, the first distal slot is defined transverse to the longitudinal axis, the second distal slot extends along a length of the longitudinal axis, the second distal slot distal of the first distal slot. ### Claim 22 (depends on 21) The buttress material according to claim 21, wherein the elongate body includes a tab distal of the second distal slot.
