    Abstract: A tissue thickness compensator may generally comprise a first layer comprising a first biocompatible material sealingly enclosed in a water impermeable material and a second layer comprising a second biocompatible material comprising at least one encapsulation, wherein the first biocompatible material expands when contacted with a fluid. The tissue thickness compensator may comprise a haemostatic agent, an anti-inflammatory agent, an antibiotic agent, anti-microbial agent, an anti-adhesion agent, an anti-coagulant agent, a medicament, and/or pharmaceutically active agent. The encapsulation may comprise a biodegradable material to degrade in vivo and/or in situ. The tissue thickness compensator may comprise a hydrogel. The reaction product may comprise a fluid-swellable composition. Articles of manufacture comprising the tissue thickness compensator and methods of making and using the tissue thickness compensator are also described.

    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: A surgical instrument includes a body, a shaft assembly, a stapling head assembly, and a drive assembly. The shaft assembly includes an actuator. The stapling head assembly is operable to drive an annularly arranged array of staples into tissue in response to translation of the actuator along a first axis relative to the body. The drive assembly is operable to translate the actuator along the first axis. The drive assembly comprises first and second rotary members. The first rotary member is rotatable about a second axis. The second axis is non-parallel with the first axis. The second rotary member is rotatable about a third axis. The third axis is non-parallel with the first axis and non-parallel with the second axis. The first rotary member is operable to drive the second rotary member to rotate about the third axis to thereby drive the actuator along the first axis.

    Abstract: Methods and devices for using surgical devices with articulating end effectors are provided. Surgical devices with articulating end effectors can provide rotary driven pivoting of the end effector. In some embodiments, the device can include a handle, a first and a second tube extending from the handle, the second tube disposed within the first tube, and an end effector that includes a pair of distal jaws configured to move in response to rotation of the first tube about a longitudinal axis thereof and rotation of the second tube about a longitudinal axis thereof. The jaws can move in two different ways depending on whether the first and second tubes are rotating in a same direction as one another or in different ways than each other. The jaws can open/close and articulate using the same mechanical mechanism. The device can be powered, or the device can be non-powered.

    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.
