A surgical stapler includes a first elongate member having a distal portion that supports an anvil surface, and a second elongate member having a distal portion configured to receive a staple cartridge. The stapler further includes a pin rotatably coupled with the first elongate member, and a clamp member movably coupled with the second elongate member. The clamp member is operable to releasably capture the pin to thereby clamp the first elongate member against the second elongate member. The pin is configured to rotate relative to the first elongate member in response to being captured by the clamp member.

Clamping assembly for linear surgical stapler

Circular stapling instruments and anvil assemblies. The anvil assemblies may have collapsible anvil support members that may be inserted through an opening in a patient and then expanded to be attached to an anvil plate assembly that has a staple-forming surface thereon. The anvil support member is attachable to the anvil plate assembly in such a way that when the anvil assembly is coupled to the stapling head of a circular stapler, the staple-forming surface is in substantial registry with the staples supported in the stapling head. A variety of different anvil support members and anvil plate assemblies are disclosed.

Anvil assemblies for circular staplers

Anvil assemblies with collapsible frames for circular staplers

A sterile packaging assembly configured to receive a surgical instrument is disclosed. The sterile packaging assembly comprises a vacuum-molded tray and a particulate trap. The vacuum-molded tray comprises an instrument cavity configured to receive the surgical instrument, and a trap cavity. The particulate trap is positioned in the trap cavity. The particulate trap comprises a housing including a funnel shaped side terminating in an opening. The opening is in communication with a chamber defined in the particulate trap.

Collapsible anvil plate assemblies for circular surgical stapling devices

A surgical stapler configured to clamp, staple, and cut tissue is disclosed. The surgical stapler comprises a housing, a shaft, a staple cartridge, an expandable anvil, and a distal head portion. The shaft extends from the housing and comprises three concentric actuators. The three concentric actuators are operable independently of each other. The three concentric actuators are actuatable relative to the housing and are configured to perform three separate and distinct end effector functions. The staple cartridge comprises a unitary cartridge body. The distal head portion is configured to rotate relative to the shaft. One of the separate and distinct end effector functions comprises rotating the distal head portion to expand the anvil.

Circular surgical staplers with foldable anvil assemblies

An end effector for stapling and cutting tissue is disclosed. The end effector comprises a housing, staples removably stored in the housing, a cutting portion configured to cut the tissue, and a collapsible ring. The ring is deployable between a first configuration and a second configuration to engage the tissue. The end effector further comprises an actuator configured to deploy the ring between the first configuration and the second configuration and pull the tissue within the cutting portion after the ring has been engaged with the tissue.

Surgical instrument

An assembly for fastening tissue is disclosed. The assembly may comprise a first jaw comprising a cartridge, wherein the cartridge comprises a plurality of fasteners. The plurality of fasteners comprises a first fastener comprising a first height and a second fastener comprising a second height, wherein the second height is different than the first height. The assembly further comprises a second jaw, wherein at least one of the first jaw and the second jaw is movable relative to the other. The second jaw comprises a plurality of fastener-engaging portions. The plurality of fastener-engaging portions comprises a first fastener-engaging portion and a second fastener-engaging portion. The assembly further comprises a compressible layer intermediate the first jaw and the second jaw.

Assembly for fastening tissue comprising a compressible layer

In various embodiments, a surgical instrument is provided that may comprise an end effector for performing a surgical procedure on tissue, for example. The end effector may comprise at least one energy delivery surface and heat dissipation means for dissipating heat from at least a portion of the end effector. For example, in at least one embodiment, the end effector may comprise a first jaw, a second jaw, and a cutting member. The cutting member may comprise a cutting surface and a body, which may define a cavity and at least one opening communicating with the cavity. A fluid may be moved through the cavity to and/or from the opening(s). Additionally, in at least one embodiment, a surgical instrument's end effector may comprise a first jaw, a second jaw, a cutting member, and at least one heat pipe. Various other heat dissipation means are also disclosed.

Heat management configurations for controlling heat dissipation from electrosurgical instruments

A tissue thickness compensator can comprise a plurality of layers. Various embodiments are disclosed herein for manufacturing a tissue thickness compensator. In certain embodiments, a tissue thickness compensator can comprise at least one medicament tube, capsule, and/or packet contained therein.

Tissue thickness compensator comprising a plurality of capsules

In various embodiments, a tissue thickness compensator can comprise a compressible extracellular matrix and a bioabsorbable material dispersed within the extracellular matrix, wherein the bioapsorption of the bioabsorbable material is configured to leave behind channels in the extracellular matrix. The tissue thickness compensator can also comprise generation means for generating the ingrowth of tissue into the channels. In at least one embodiment, the tissue thickness compensator can comprise dissolvable wicking members which, when dissolved, can leave behind channels in the tissue thickness compensator. In certain embodiments, the tissue thickness compensator can comprise at least one rupturable capsule.

Tissue thickness compensator comprising a reservoir
