Staple cartridge comprising offset longitudinal staple rows

A staple cartridge assembly is disclosed which comprises offset staple rows.

Staple cartridge comprising wire staples and stamped staples

A staple cartridge assembly is disclosed. The staple cartridge assembly includes one or more wire staples and one or more staples formed from a sheet of material. For example, the staple cartridge assembly can include an arrangement of diverse staples. A first type of staple can be arranged in a first longitudinal row and a second type of staple can be arranged in a second longitudinal row. The first type of staple can be wire staples supported by staple drivers. The second type of staples can be formed from a flat sheet of material and can each include an integral driver. A sled can be configured to engage the staple drivers to eject the first type of staples and to directly engage the integral drivers of the second type of staples to fire the arrangement of diverse staples from the staple cartridge assembly.

Stamped staples and staple cartridges using the same

A staple cartridge assembly is disclosed which comprises staples including a crown, a cam surface extending from the crown, one or more staple legs, and one or more connectors which connect the staple legs to the crown. The staple cartridge assembly further comprises a sled configured to engage the cam surfaces of the staples but not the connectors.

Staple cartridge comprising overdriven staples

A staple cartridge assembly is disclosed which comprises staples formed from one or more sheets of material. The staples are removably stored in a cartridge body comprising a deck configured to support the tissue of a patient. The staple cartridge assembly further comprises a sled configured to sequentially engage the staples and lift the staples between unfired and fired positions. The staples comprise a tissue engaging surface which is deployed above the deck when the staples are moved into their fired positions.

Stapling system for use with wire staples and stamped staples

A staple cartridge system is disclosed. The staple cartridge system can be used interchangeably with different staple cartridges. For example, the staple cartridge system can be used interchangeable with a staple cartridge comprising wire staples and with a staple cartridge comprising stamped staples. The stamped staples can be stamped from a sheet of flat stock.

Tissue thickness compensator configured to redistribute compressive forces

A surgical stapler comprising a first jaw comprising a first bioabsorbable matrix and a second jaw comprising a second bioabsorbable matrix is disclosed. At least one of the first jaw and the second jaw is moveable between an open position and a closed position to clamp tissue between the first bioabsorbable matrix and the second bioabsorbable matrix. At least one of the first bioabsorbable matrix and the second bioabsorbable matrix comprises a plurality of layers including a fibrous layer. The fibrous layer comprises a plurality of deformable structures each having an equilibrium configuration. The deformable structures are expandable and compressible from the equilibrium configurations to reshape the fibrous layer and accommodate for variations in tissue thickness when tissue is clamped between the first bioabsorbable matrix and the second bioabsorbable matrix.

Control systems for surgical instruments

Surgical instruments and control systems therefor are disclosed. A surgical instrument can comprise: a power circuit comprising a power source and a switch, a microcontroller coupled to the power circuit, a handle comprising an attachment portion, and a control circuit in signal communication with the microcontroller. The attachment portion can comprise a first electrical contact in signal communication with the microcontroller. The control circuit can comprise a sensor configured to detect an attachment state of the attachment portion. The control circuit can communicate the detected attachment state to the microcontroller, and the microcontroller can ignore signals from the first electrical contact when the control circuit communicates a detached state. The attachment portion can comprise a second electrical contact coupled to a second power circuit, and the second power circuit can decouple the second electrical contact and the second power source when the sensor detects the detached state.

Formation of epitaxial layers via dislocation filtering

A process for forming a thick defect-free epitaxial layer is disclosed. The process may comprise forming a buffer layer and a sacrificial layer prior to forming the thick defect-free epitaxial layer. The sacrificial layer and the thick defect-free epitaxial layer may be formed of the same material and at the same process conditions.

Instrument device manipulator with back-mounted tool attachment mechanism

An instrument device manipulator (IDM) is attached to a surgical arm of a robotic system and comprises a surgical tool holder and an outer housing. The surgical tool holder includes an attachment interface that can secure a surgical tool in a front-mount configuration (where the attachment interface is on a face opposite of an elongated body of the surgical tool) or a back-mount configuration (where the attachment interface is on the same face as the elongated body of the surgical tool). The surgical tool holder may rotate continuously within the outer housing. In a back-mount configuration, the surgical tool holder may have a passage that receives the elongated body of the tool and allows free rotation of the elongated body about the rotational axis. A surgical drape separates the IDM and robotic arm from a tool, while allowing electrical and/or optical signals to pass therebetween.

Fabrication of a vertical fin field effect transistor with an asymmetric gate structure

A method of forming a vertical fin field effect transistor (vertical finFET) with two concentric gate structures, including forming one or more tubular vertical fins on a substrate, forming a first gate structure around an outer wall of at least one of the one or more tubular vertical fins, and forming a second gate structure within an inner wall of at least one of the one or more tubular vertical fins having the first gate structure around the outer wall.
