The actuation mechanism includes an activation structure configured to move each of the link assemblies and sequentially cause each of the link assemblies to move through a succession of motions within the cartridge body, such that the link assemblies cause the corresponding pusher to contact and, subsequently, sequentially eject the associated surgical fastener towards the depression in the anvil.

Introducer system and assembly for surgical staplers

An introducer assembly for use with a surgical stapler is provided. The introducer assembly includes an elongated main body portion, one or more mounting mechanisms associated with the main body portion, and a plurality of petals or fingers positioned at a distal end of the elongated main body portion. The one or more mounting mechanisms are adapted to detachably mount with respect to the surgical stapler. The plurality of petals or fingers define a distal junction and a proximally-directed mounting member that is adapted to detachably engage a distal portion of the surgical stapler. The plurality of petals or fingers define an inner region that accommodates a distal end of the surgical stapler. The distal junction and the proximally-directed mounting member associated with the plurality of petals or fingers are adapted to disengage upon application of a requisite proximally-directed force to the elongated body portion. Methods and combinations that utilize the introducer are also disclosed.

Mobile phone payment processing methods and systems

Embodiments provide systems, methods, processes, and computer program code for using mobile devices to conduct payment transactions at merchant locations including brick and mortar locations and remote locations as well as for person to person transactions.

Electrosurgical cutting and sealing instruments with cam-actuated jaws

Various embodiments are directed to a surgical instrument comprising, a shaft, and an end effector. The shaft may be coupled to the handle and may extend distally along a longitudinal axis. The end effector may be positioned at a distal end of the shaft and may comprise first and second jaw members and a reciprocating member. The first and second jaw members may define first and second longitudinal slots. One or both of the jaw members may be pivotable relative to the other about a pivot point. The reciprocating member may be translatable distally and proximally parallel to the longitudinal axis and through the first and second longitudinal slots. A distal portion of the reciprocating member may define a blade. The instrument may comprise an overtube translatable distally to exert a force on a portions of the first and second jaw members tending to close the first and second jaw members.

Optical hydrology arrays and system and method for monitoring water displacement during treatment of patient tissue

A system that monitors water displacement in tissue during patient therapy includes a generator supplying electrosurgical energy to tissue, a spectrometer operably coupled to the generator, and a processor communicating with the generator and with the spectrometer having a light source for exposing tissue to light and a light sensor. The light sensor is configured to sense changes in light through tissue in response to tissue treatment and communicate the changes to the processor to determine tissue hydration levels and motility. A plurality of optical fibers may be configured in an array to communicate light between the generator and tissue. An optical temperature monitor may communicate with the processor and be coupled to an optical fiber. The optical fibers may have an optic fiber distance between adjacent optical fibers. The system may be incorporated within an electrosurgical pencil or a forceps. A corresponding method of detecting hydration is also disclosed.

Surgical instrument with non-contact electrical coupling

A surgical instrument includes a reusable base component including a handle and an electrically activatable modular component removably coupled to the base component. The modular component includes an end effector operable from the handle to treat tissue. The end effector is responsive to manipulation of the handle. A first energy storage component is disposed onboard the base component and is electrically coupled to a source of electricity. A second energy storage component is disposed onboard the modular component and is electrically insulated from the first energy storage component. The second energy storage component is arranged such that a current may be selectively induced in the modular component by delivery of electrical energy to the first energy storage component.

Apparatus for aspirating, irrigating and cleansing wounds

An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.

Avatar editing environment

An avatar editing environment is disclosed that allows users to create custom avatars for use in online games and other applications. Starting with a blank face the user can add, rescale and position different elements (e.g., eyes, nose, mouth) on the blank face. The user can also change the shape of the avatar's face, the avatar's skin color and the color of all the elements. In some implementations, touch input and gestures can be used to manually edit the avatar. Various controls can be used to create the avatar, such as controls for resizing, rotating, positioning, etc. The user can choose between manual and automatic avatar creation. The avatar editing environment can be part of a framework that is available to applications. One or more elements of the avatar can be animated.

Cloud based operating and virtual file system

A method for managing a virtual distributed file system includes maintaining by a master device located in a cloud computing environment, a metadata data structure that stores metadata about locations of most updated versions of multiple file portions and security levels of the file portions, at least one file portion being stored at a user device coupled to the cloud computing environment, and maintaining by the master device, transaction of file portions to user entities, at least one user entity being hosted by the user device, based on at least metadata stored in the metadata data structure about the file portions.

Cable actuated end-effector for a surgical instrument

Various embodiments are directed to a surgical instrument comprising a handle, a shaft coupled to the handle and extending along a longitudinal axis, an end effector, and a cable. The end effector may comprise a first jaw member, a second jaw member and a reciprocating member. The cable may extend distally from the handle through the shaft to a first pulley of the first jaw member. From the first pulley, the cable may extend proximally to the reciprocating member, such that proximally directed motion of the cable exerts a distally directed force on the reciprocating member.
