A method of preparing a staple cartridge includes forming first staples with a first alloy, and forming second staples with a second alloy that is different than the first alloy. The method includes positioning the first staples into staple cavities of a first row of staple cavities of the staple cartridge, the first row of staple cavities being a first distance from an elongate slot of the staple cartridge, and positioning the second staples into staple cavities of a second row of staple cavities, the second row of staple cavities being a second distance from the elongate slot of the staple cartridge. The second distance is greater than the first distance. The first staples are configured to degrade at a first rate in a tissue environment, and the second staples are configured to degrade at a second rate that is different than the first rate.

Method for implementing a staple system

Various exemplary devices and methods are provided for performing surgical procedures. In general, one or more adjuncts can be used in conjunction with surgical instruments. The adjunct(s) can have medicant(s) thereon and/or therein. The medicant(s) can vary depending on the desired effect of the medicant(s) on surrounding tissue. As a non-limiting example, medicant(s) can be provided to influence hemostasis, inflammation, macrophages, and/or fibroblasts. When used in conjunction with a surgical stapler, the adjunct(s) can be disposed between and/or on jaws of the stapler, incorporated into a staple cartridge disposed in the jaws, or otherwise placed in proximity to the staples. When staples are deployed, the adjunct(s) can remain at the treatment site with the staples.

Medicant eluting adjuncts and methods of using medicant eluting adjuncts

The disclosed technology includes a bioabsorbable material configured to be delivered to tissue. The material includes a shape-memory polymer compressible in a delivery configuration and configured to swell within a predetermined period of time. The shape-memory polymer includes one or more functional groups for reversible bonding between adjacent functional groups to transition between an approximately linear polymer and an approximately non-linear polymer upon exposure to a stimulation.

Systems and methods for customizing mechanical strength in stimuli-responsive bioabsorbable materials

A staple cartridge is disclosed. The staple cartridge can comprise a cartridge body comprising a deck and a bottom surface opposite the deck. The staple cartridge can comprise a plurality of staple cavities, wherein each staple cavity extends into the cartridge body from the deck to the bottom surface. Additionally, a plurality of wells can be defined into the staple cartridge from the deck to a lowermost surface of the well. A plurality of staples can be removably positioned in the staple cavities. The staple cartridge can comprise a tissue thickness compensator releasably secured to the cartridge body, wherein the tissue thickness compensator comprises a compensator body and a plurality of extensions extending from the compensator body into the wells, wherein at least one extension is compressed within one of the wells. Each well can surround at least one staple cavity and/or can extend between at least two staple cavities.

Staple cartridge comprising a tissue thickness compensator

A method for controlling a surgical instrument is disclosed. In at least one instance, the surgical instrument comprises a shroud and the operation of the surgical instrument is modified based on input from a sensing circuit configured to sense a parameter of the shroud. In certain instances, the surgical instrument comprises a strain gage circuit and the operation of the surgical instrument is modified based on input from the strain gage circuit.

Surgical instrument comprising flex circuit

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.

Compressible adjunct with crossing spacer fibers

An assembly includes an applicator, which includes a housing defining a gap configured to receive an end effector jaw of a surgical stapler. The applicator also includes a platform positioned within the gap. The assembly also includes a buttress assembly having a first length and positioned on the platform. The assembly further includes a trimming feature presented by the applicator or the buttress assembly, and configured to facilitate trimming of the buttress assembly from the first length to a predetermined second length.

Surgical stapler buttress with variable length feature

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 method for adaptive control of surgical network control and interaction is disclosed. The surgical network includes a surgical feedback system. The surgical feedback system includes a surgical instrument, a data source, and a surgical hub configured to communicably couple to the data source and the surgical instrument. The surgical hub includes a control circuit. The method includes receiving, by the control circuit, information related to devices communicatively coupled to the surgical network; and adaptively controlling, by the control circuit, the surgical network based on the received information.

Method for adaptive control schemes for surgical network control and interaction

An adjunct for use with a surgical stapling system is disclosed. The adjunct comprises a first region. The first region comprises a first composition. The adjunct comprises a second region. The second region is distal to the first region and comprises a second composition. The adjunct comprises a third region. The third region is distal to the second region. The third region comprises a third composition. The second composition differs from the first composition and the third composition.

Adjuncts for use with surgical stapling instruments

A surgical instrument includes a first and second jaw, a firing assembly, a first buttress assembly, and a second buttress assembly. The first and second jaw actuate relative to each other between an open and closed position to grasp tissue. The second jaw includes a fastening assembly having a deck defining a plurality of openings and a plurality of fasteners housed within the openings. The firing assembly drives the plurality of fasteners out of the plurality of openings against a plurality of fastening forming features of the first jaw. The first buttress assembly and the second buttress assembly are associated with the first and second jaw, respectively. The first buttress assembly includes a first material and a first thickness. The second buttress assembly includes a second material and a second thickness. The first material and the second material differ in rigidity. The first thickness and the second thickness are different.

Tissue cushion adjuncts for surgical stapler end effector

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

Staple cartridge systems with implantable adjuncts and retainers are disclosed. The staple cartridge systems ensure the full-cutting of the implantable adjuncts through the structure/manufacturing of the implantable adjuncts and the retainers.
