    Abstract: A method of applying a buttress to a surgical stapler end effector comprises positioning a buttress assembly between an anvil and a staple cartridge of the end effector. The buttress assembly comprises a buttress body and an adhesive material. The adhesive material faces either an underside of the anvil or a deck of the staple cartridge. The anvil is in an open position relative to the staple cartridge during the act of positioning the buttress assembly between the anvil and the staple cartridge. The method further comprises moving the anvil toward the staple cartridge then moving the anvil back to the open position. The buttress assembly is adhered to the underside of the anvil or the deck of the staple cartridge via the adhesive material with the anvil moved back to the open position. The adhesive material comprises a bioabsorbable polymer.

    Abstract: An apparatus comprises a body, a shaft assembly, an end effector, a cartridge, and a staple driver actuator. The end effector is operable to manipulate tissue. The end effector comprises a lower jaw, a pivotable anvil, and a translating cutter. The translating cutter is operable to translate relative to the lower jaw and the anvil when the anvil is pivoted toward the lower jaw to manipulate tissue. The cartridge is insertable into the lower jaw and includes a plurality of staples. The staple driver actuator is disposed within the cartridge. The staple driver actuator comprises a secondary cutting element. The translating cutter of the end effector is operable to drive the staple driver actuator distally to staple and cut tissue substantially simultaneously.

    Abstract: An apparatus includes a body, a shaft assembly, an end effector, and a staple cartridge. The end effector includes an anvil and a lower jaw. The anvil is pivotable toward the lower jaw to capture tissue between the anvil and the lower jaw. The staple cartridge is coupled with the lower jaw. The staple cartridge includes a deck and a plurality of staples. The deck faces the anvil. The anvil or the deck (or both) includes a compressible that extends toward the other of the anvil or the deck. The compressible feature of the anvil of the deck is configured to compress tissue against the other of the anvil or the deck.
