Implantable adjuncts for use with a surgical instrument are disclosed. The implantable adjunct includes a first mesh positioned about a first side of the longitudinal knife slot and a second mesh positioned about a second side of the longitudinal knife slot such that the first and second meshes define a gap substantially aligned with the longitudinal knife slot of the staple cartridge body.

Implantable adjunct with density gradients

A system and method for evaluating an operational capacity of a powered surgical system is disclosed. A sensor is configured to monitor an operational condition of the powered surgical system. A control circuit is configured to receive the operational condition of the powered surgical system from the sensor, store the received operational condition of the powered surgical system in the memory, evaluate the operational capacity of the powered surgical system based on the stored operational condition of the powered surgical system, and disable the powered surgical system in response to the evaluation of the operational capacity of the powered surgical system.

Evaluating operational capacity of a power surgical system

A fastener cartridge can comprise fastener cavities arranged in longitudinal rows. A first fastener having a first configuration and a second fastener having a second configuration can be stored within a longitudinal row. First fasteners having a first configuration can be stored within a first longitudinal row and second fasteners having a second configuration can be stored within a second longitudinal row. Each first fastener can have a proximal leg, or leg portion, extending at a first proximal angle and a distal leg, or leg portion, extending at a first distal angle and each second fastener can have a proximal leg, or leg portion, extending at a second proximal angle and a distal leg, or leg portion, extending at a second distal angle. The first proximal angle can be different than the second proximal angle and/or the first distal angle can be different than the second distal angle.

Fastener cartridge and fastener cartridge layer

A buttress is applied to an end effector of a surgical stapler. The buttress is loaded on a platform of a buttress applier cartridge. The end effector is closed upon the platform. An adhesive layer of the buttress secures the buttress to the end effector. The buttress is thus adhered to the end effector when the end effector is opened. The end effector is then actuated on tissue of a patient, thereby stapling the buttress to the tissue.

Method of applying a buttress to a surgical stapler end effector

A staple cartridge assembly for use with a surgical stapling instrument is disclosed. The staple cartridge assembly comprises a compressible adjunct and a staple cartridge. The compressible adjunct comprises attachment regions. The staple cartridge comprises a proximal end, a distal end, a deck, a longitudinal row of staple cavities, staples, bonding zones, and barbs. The attachment regions of the compressible adjunct are configured to be secured to bonding areas defined by the bonding zones. The barbs protrude from the deck, and the barbs are configured to maintain an initial alignment between the attachment regions and the bonding zones prior to attachment of the compressible adjunct to the deck.

Compressible adjunct with attachment regions

An apparatus includes a body, a shaft, a stapling head assembly, and an anvil. The body includes a motor, a first user input feature, and a second user input feature. The first user input feature is operable to activate the motor. The shaft extends distally from the body. The stapling head assembly is positioned at a distal end of the shaft. The stapling head assembly includes an anvil coupling feature, at least one annular array of staples, and a staple driver. The second user input feature is operable to drive the anvil coupling feature longitudinally. The staple driver is operable to drive the at least one annular array of staples. The motor is operable to drive the staple driver. The anvil is configured to couple with the anvil coupling feature. The anvil is further configured to deform the staples driven by the staple driver.

Methods and systems for performing surgical stapling

A method of applying a buttress to a surgically cut and stapled site uses an end effector with a buttress applier cartridge assembly to load one or more buttress assemblies to the end effector. The buttress assemblies each include a buttress to support a staple formed therein as well an adhesive for adhering to the end effector. The adhesive of the buttress assemblies can include a pattern to assist in both attachment to the end effector and release from the end effector after cutting and stapling a tissue site. The buttress applier cartridge can include features that accommodate end effectors having various tip configurations, including straight tips and curved or bent tips.

Method of applying buttresses to surgically cut and stapled sites

Devices and methods are provided for stabilizing fasteners post-deployment. Devices and methods are also provided for facilitating ejection of surgical fasteners from a cartridge. Devices and methods are also provided for guiding surgical fasteners. Devices and methods are also provided for facilitating closing and clamping of an end effector of a surgical device. Devices and methods are also provided for securing fasteners and adjunct materials to tissue. Devices and methods are also provided for removably coupling a cartridge to an end effector of a surgical device. Devices and methods are also provided for locking a surgical device based on loading of a fastener cartridge in the surgical device. Devices and methods are provided for adjusting a tissue gap of an end effector of a surgical device. Devices and methods are also provided for manually retracting a drive shaft, drive beam, and associated components.

Devices and methods for facilitating ejection of surgical fasteners from cartridges

A surgical instrument system can comprise a surgical instrument, a first end effector, and a second end effector, wherein the end effectors are attachable to the surgical instrument. The first end effector can comprise a first set of stored data pertaining to the first end effector, wherein the surgical instrument is configured to ascertain the first set of data and enter a first operating state. The second end effector can comprise a second set of stored data pertaining to the second end effector, wherein the surgical instrument is configured to ascertain the second set of data and enter a second operating state. The surgical instrument is further configured to enter a default operating state if said surgical instrument is unable to ascertain a set of stored data from an end effector.

Methods and systems for performing circular stapling

Anvil for use with a surgical stapling assembly

A surgical system including a surgical instrument, a surgical visualization system, a display, and a feedback controller are presented. The feedback controller is in signal communication with the surgical instrument and the surgical visualization system. The feedback controller is configured to display, on the display, during an operation, live images derived from the surgical visualization system in a first layer and a status of the surgical instrument in a second layer. The status is configured to locate itself in said second layer in relation to a depiction of a feature of the surgical instrument and/or a feature of tissue in the first layer. The surgical instrument can include a surgical stapler, a knife, a robotic surgical instrument, combination thereof, or variation thereof.

Torque optimization for surgical instruments

A surgical stapler, or fastening instrument, may generally comprise a layer, such as a tissue thickness compensator, for example, releasably attached to a fastener cartridge and/or anvil by a flowable attachment portion. The flowable attachment portion may be indefinitely flowable. The flowable attachment portion may be flowable from the time that layer is installed to the fastener cartridge to the time in which the layer is implanted to patient tissue. The flowable attachment portion may comprise a pressure sensitive adhesive. The flowable attachment portion may comprise an adhesive laminate comprising a base layer comprising the tissue thickness compensator and an adhesive layer on at least a portion of a surface of the base layer comprising the pressure sensitive adhesive. Articles of manufacture comprising flowable attachment portion and methods of making and using the flowable attachment portion are also described.
