Staple systems and methods for implementing the staple systems are disclosed.

Bioabsorbable staples are disclosed that have sufficient mechanical properties throughout a healing window of patient tissue.

Staple cartridges comprising absorbable staples having sufficient mechanical properties to be deployed into patient tissue, clench the patient tissue, and then dissolve within a desired time frame.

A staple cartridge comprising absorbable staples having co-operate and/or antagonistic coatings is disclosed.

A method and apparatus of adaptively controlling a surgical stapling instrument are disclose. The method includes identifying a staple cartridge type, configuring the surgical stapling instrument based on the identified staple cartridge, and adaptively controlling, by a control circuit, operation/functionality of the surgical stapling instrument based on the configuration of the surgical stapling instrument loaded with the identified staple cartridge type. The apparatus includes a control circuit including a microcontroller and a memory coupled to the microcontroller. The memory stores machine executable instructions that when executed by the microcontroller cause the microcontroller to execute the above method.

Packaging assemblies for storing and shipping surgical staple cartridges containing bio-absorbable staples.

A cannula assembly having a retention member and a method of manufacture of the cannula assembly is provided. The cannula assembly includes a cannula and a sleeve disposed around the cannula from a proximal end to a distal end. The sleeve can include a balloon formed by a stretch blow molding process following local heating once advanced over the cannula. Once formed, the balloon can be conditioned to constrict against the cannula. A conditioning aid can be advanced over the balloon when it is still formable to constrict the balloon against the cannula.

A fastener cartridge can include, one, a cartridge body comprising a deck and a plurality of fastener cavities and, two, a plurality of fasteners positioned in the fastener cavities. The cartridge body can further comprise extensions extending from the deck having different sizes and/or configurations. The extensions can control the flow of tissue relative to the deck and/or support the fasteners as they are ejected from the fastener cavities.

An end effector including an anvil and a staple cartridge assembly is disclosed. The staple cartridge assembly comprises a deck having steps defined thereon for compressing tissue positioned between the anvil and the staple cartridge assembly to different pressures. The staple cartridge assembly further comprises staples having different unformed heights removably stored therein. The staples are deformed against the anvil to different formed heights.
