A staple cartridge comprising a power management circuit is disclosed.

Disclosed is a surgical end effector for use with a surgical instrument. The surgical end effector comprises a jaw, and a staple cartridge seatable in the jaw. The staple cartridge comprises a sensor array configured to take measurements corresponding to a parameter associated with a function of the surgical instrument, a processor, and a memory storing program instructions. The memory storing program instructions that, when executed by the processor, cause the processor to perform an initial calibration of the sensor array, determine an initial adjustment to the measurements based on the initial calibration, perform an in-use calibration of the sensor array, and modify the initial adjustment based on the in-use calibration.

A staple cartridge comprising a memory device and a system configured to limit access to data stored on the memory device is disclosed.

A staple instrument system comprising a cartridge body and an antenna is disclosed.

A surgical end effector includes a cartridge. The cartridge includes first and second sensor arrays disposed in the cartridge. The first sensor array is configured to sense a function of a first component located within the cartridge and the second sensor array is configured to sense a function of a second component located within the cartridge. The first and second sensor arrays are electrically coupled to an electronic circuit. The electronic circuit includes a control circuit configured to receive signal samples from the first sensor array, receive signal samples from the second sensor array, and process the signals samples received from the first and second sensor arrays to determine a status of the cartridge.

A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.

A retainer system for use with staple cartridges configured for use with a surgical stapling device is disclosed. The retainer comprises a retainer body that is configured to be attached to the staple cartridge by retention features. The system includes a tool that moves the retention features between a first state wherein the retention features prevent the retainer from being attached to the staple cartridge to a second state where the retainer may be coupled to the staple cartridge by the retention features.

A deactivator element for use with a staple cartridge is disclosed. The deactivator element is configured to be removably supported on the staple cartridge in a deactivator position. When the deactivator element is supported on a staple cartridge in the deactivator portion and the staple cartridge is seated in a surgical stapling device, a cam surface on the deactivator element defeats a lockout in the surgical stapling device.

Embodiments disclosed herein include an embolization material. The embolication material includes a tubular strand, with an outer surface, having a distal end and a proximal end, wherein the outer surface defines one or more slits.

A cover member for a surgical staple cartridge. The cover member is configured to retain a wedge sled within the staple cartridge in a starting position when the cover member is attached to the body of the staple cartridge. The cover member includes a top portion that covers all of the fastener openings in the deck of the staple cartridge when the cover is attached to the cartridge.
