A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.

A fastener cartridge assembly that comprises a cartridge body, a proximal end, a distal end, a plurality of fastener cavities, a slot configured to receive a cutting member, a row of first fasteners, a row of second fasteners, a first fastener driver, a second fastener driver, and a sled is disclosed. The sled comprises a first ramp configured to lift said first fastener driver and said first fastener toward an anvil. The anvil and said first fastener driver are configured to cooperatively deform said first fastener to a first fired height. The sled further comprises a second ramp configured to lift said second fastener driver and said second fastener toward the anvil. The anvil and said second fastener driver are configured to cooperatively deform said second fastener to a second fired height. The second fired height is different than said first fired height.

A surgical fixation method including use of a fixation device and an introducer.

A medical staple is provided with: a rectangular base portion; and a needle portion that extends from one end of the base portion in a substantially arc shape so as to protrude in a predetermined direction with respect to the base portion, wherein the needle portion has a first bending position that is provided between a base connected at the one end and a distal end, and that yields first when a pressing force in a radially inward direction of an arc shape of the needle portion acts on the distal end, and a second bending position that is provided between the first bending position and the base, and that yields first when the pressing force acts in the vicinity of the base of the first bending position.

An adapter assembly includes a switch actuator, an actuation bar, and a latch. The switch actuator is movable between a proximal position, in which the switch actuator actuates a switch, and a distal position. The latch is movable between a first position, in which the latch permits proximal movement of the switch actuator, and a second position, in which the latch prevents proximal movement of the switch actuator. The latch is configured to move from the first position toward the second position in response to the actuation bar moving toward a proximal position.

A gastroscopic method and instrument for treating obesity of a patient, using a device adapted to stretch a part of the stomach wall of said patient. The method comprises the steps of: inserting the device into the stomach through the esophagus, placing the device in contact with the stomach wall, and fixating the device to the stomach wall such that the device can stretch a part of the stomach wall.

An apparatus and a method are provided for a sterile staple implant kit that a surgeon may unpack and utilize during a surgery. The staple implant kit comprises a group of complementary surgery-specific instruments that are packaged in a sterile state, An instrument tray is configured to preserve the instruments in the sterile state until the staple implant kit is opened during the surgery. The instrument tray is configured to provide the surgeon with easy access to the instruments during the surgery. The staple implant kit comprises at least a staple inserter and a surgical staple suitable for being implanted in parallel holes drilled across a bone fusion or fixation site of a patient. The surgical staple preferably is loaded in a relaxed configuration into the staple inserter. A staple retention clip retains the surgical staple in the staple inserter until the staple is distracted during the surgery.

A surgical instrument that includes a housing that defines a longitudinal axis. An elongated shaft assembly is operably coupled to the housing by a shaft rotator assembly for selective rotation about the longitudinal axis relative to the housing. A first motor is supported by the housing and configured to selectively apply first rotary actuation motions to a first drive shaft that is operably supported by the housing and operably interfaces with a first shaft actuator. A second motor is supported by the shaft rotator assembly such that the second motor is rotatable about the longitudinal axis and is configured to apply second rotary actuation motions to a second shaft actuator.

A surgical kit includes an instrument and two or more cartridges. The instrument includes a body, a shaft assembly, and a cartridge receiving assembly. The cartridge receiving assembly has a movable output feature, which is configured to move in response to activation of the actuation input feature. The cartridges may include a first suturing cartridge and a second suturing cartridge, with first and second suture needles, respectively. The second suture needle may extend along an arc that has a larger radius of curvature than an arc associated with the first suture needle. The cartridges may also include a drive assembly that is operable to drive the needle along an orbital path in response to movement of the actuation input feature. The cartridges may also include features that are operable to apply clips or staples. The cartridges may also include features that are operable to grasp or cut.

An assembly used in osteosynthesis comprising a delivery instrument in combination with an implant wherein the delivery instrument releasably holds the implant in a first configuration prior to attachment of the implant to bone. The delivery instrument allows the implant to be affixed to bone before the implant is released from the instrument. And the instrument may comprise guide means for drills, depth gauges, screws, pins, pegs, blades and or drivers which are used or implanted when the implant is releasably attached to the instrument. After the implant is affixed to bone and released from the delivery instrument, the implant assumes at least a second configuration which provides compression and or distraction and or control of spatial orientation.
