Methods for treating tissue are provided. In one embodiment, an adjunct material, when secured to tissue, can receive at least one physiological element released from the tissue during healing progression of the tissue, and can exhibit first and second stiffnesses in compression that are approximately constant during first and second time periods from contact with the tissue, with the second stiffness decreasing with time as a function of at least one of oxidation, enzyme-catalyzed hydrolysis, and change of pH resulting from interaction with the at least one physiological element. In another embodiment, the adjunct can receive a unit volume of fluid that causes first and second portions of the adjunct to expand according to first and second expansion behaviors that differ from one another to apply different pressures to the tissue.

Method for treating tissue

A stapling assembly includes a cartridge, an anvil, and an adjunct. The cartridge has rows of staples disposed therein for deployment into tissue. The cartridge includes a knife slot extending therethrough between the rows for receiving a knife to cut tissue. The anvil is positioned opposite the cartridge. The adjunct is releasably retained on the cartridge or the anvil. The adjunct can be delivered to tissue by deployment of the staples from the cartridge. The adjunct can have a first shape, and a first adjunct portion can exhibit first expansion behavior in response to receipt of a volume of fluid, and a second adjunct portion can exhibit second expansion behavior in response to receipt of the volume of fluid such that the adjunct adopts a second shape. The difference between the first and second expansion behavior applies different pressures to different portions of tissue having the adjunct stapled thereto.

A material for use in a medical device includes a blend of a non-melt polymer such as Polyamideimide, a meltable carrier polymer such as Polyetherketoneketone and lubricants/rheology modifiers such that the final polymer material can be extruded, pelletized and used to injection mold components for the medical device. The ratios of the Polyamideimide, Polyetherketoneketone and the lubricants are selected to provide sufficient lubricity and glass transition temperature to the material to make it appropriate for use in high temperature applications and additive manufacturing processes.

High temperature material for use in medical devices

A surgical apparatus includes an end effector having an ultrasonic blade, a clamp arm, and a clamp pad. The end effector applies ultrasonic energy at the blade. The clamp arm pivots relative to the blade. The clamp pad is positioned on the clamp arm adjacent to the blade. The clamp arm includes a latching feature to retain the clamp pad relative to the clamp arm to prevent the clamp pad from moving laterally, longitudinally, and perpendicularly relative to the clamp arm.

Clamp arm features for ultrasonic surgical instrument

A staple cartridge assembly for use with a surgical stapler. The assembly has a cartridge body having a support portion with a plurality of staple cavities with openings. There is also a plurality of staples, wherein at least a portion of each the staple is removably stored within the staple cavity. Each the staple is movable between an unfired position and a fired position, and is deformable between an unfired configuration and a fired configuration. The assembly also includes a compressible tissue thickness compensator configured to be captured within the staples. The compressible tissue thickness compensator at least partially covers the staple cavity openings. The compressed tissue thickness compensator is configured to assume different compressed heights within different the staples. The compressible tissue thickness compensator comprising a lyophilized foam having a hemostatic agent embedded therein.
