Abstract: A stapling assembly configured to be operably attached to a surgical system comprises a carrier operably supporting a cartridge assembly therein and an anvil. The stapling assembly further comprises a housing removably attachable to the surgical system and an axial drive assembly. The stapling assembly further comprises a motor supported within the housing, wherein the motor is operable to selectively transmit a rotary motion to the axial drive assembly. The motor can only transmit the rotary motion to the axial drive assembly when the housing is coupled to the surgical system and a power source is selectively coupled with the motor.

Abstract: A detachable motor-powered surgical instrument. The instrument may include a housing that includes at least one engagement member for removably attaching the housing to an actuator arrangement. A motor is supported within the housing for supplying actuation motions to various portions of a surgical end effector coupled to the housing. The housing may include a contact arrangement that is configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.

Abstract: Methods for forming an implantable layer onto a staple cartridge are disclosed.

Abstract: A compressible adjunct for use with a surgical instrument including a staple cartridge includes a biocompatible layer and a plurality of biocompatible looping members. The biocompatible looping members protrude from the biocompatible layer. Each biocompatible looping member includes a first end portion attached to the biocompatible layer, a second end portion attached to the biocompatible layer, and an intermediate curved portion extending between the first end portion and the second end portion, wherein the intermediate curved portion is further away from the biocompatible layer than the first end portion and the second end portion.

Abstract: A staple cartridge assembly comprising an implantable layer is disclosed. The implantable layer comprises a top portion, a bottom portion, and structural walls interwoven between the top portion and the bottom portion.

Abstract: A stapling system is disclosed. The stapling system comprises a handle, a shaft extending from the handle, and a disposable loading unit configured for operable attachment to the shaft. The stapling system further comprises a battery, a staple cartridge comprising a plurality of staples removably stored therein, a translatable member configured to translate within the staple cartridge to eject the staples from the staple cartridge, and a rotary drive comprising a motor configured to drive the translatable member, wherein the rotary drive is configured to selectively receive electrical power from the battery only when the disposable loading unit is attached to the shaft.

Abstract: A tissue thickness compensator may generally comprise a biocompatible material, a first component, and a second component, wherein the first component and second component form a reaction product to expand the tissue thickness compensator. The first component may comprise a first hydrogel precursor, the second component may comprise a second hydrogel precursor, and the reaction product may comprise a hydrogel. The reaction product may be formed in vivo and/or in situ by contacting the first component and the second component. The first component and/or second component may be encapsulated and configured to release the components when ruptured. 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: In various embodiments, a tissue thickness compensator can comprise a film body formed from a continuous extruded shape and, in addition, a fibrous medicament core.

Abstract: In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.
