A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.

A surgical stapling instrument comprising an end effector, an RFID tag, and a control circuit is disclosed. The end effector comprises an anvil, a staple cartridge, and a contact assembly configured to contact tissue. The staple cartridge comprises staples removably stored therein. The anvil and the staple cartridge are configurable between an open configuration and a closed configuration. The RFID tag is configured to store information about the staple cartridge. The control circuit is operably coupled to the contact assembly. The control circuit is configured to interrogate the RFID tag to determine the information about the staple cartridge, transmit an electrical signal to tissue contacting the contact assembly, determine a characteristic of the tissue contacting the contact assembly based on the electrical signal, and change an operational parameter of the surgical stapling instrument based on the characteristic of the tissue.

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.

A medical instrument has an elongated channel configured to support a staple cartridge, the staple cartridge comprising a plurality of staples. The medical instrument also has an anvil mechanically coupled to the elongated channel, wherein the anvil comprises an exterior surface extending between a proximal end and a distal end. In addition, the medical instrument has at least one electrical circuit at least partially positioned on the exterior surface of the anvil, an indicator system comprising at least one indicator, and a logic circuit electrically in electrical communication with the at least one electrical circuit and the indicator system, wherein the logic circuit is configured to activate the at least one indicator when an electrical continuity of the at least one electrical circuit is interrupted.

A compressible adjunct has a first portion, a second portion, and a middle portion. The middle portion is disposed between the first portion and the second portion. The middle portion comprises a first pillar, a second pillar, and an interconnecting member. The first pillar and the second pillar extend substantially between the first portion and the second portion. The interconnecting member is configured to engage at least the first pillar and the second pillar. When the compressible adjunct is compressed by a force, the first pillar is configured to deflect a first deflection and the second pillar is configured to deflect a second deflection. The first deflection differs from the second deflection.

Compressible adjunct

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.
