In a thin film transistor having a source electrode 6, a drain electrode 5, a gate electrode 4, a gate insulating film 3, and a channel layer 2, an amorphous oxide having an electron carrier concentration less than 1018/cm3 is used in the channel layer 2.

Surgical stapling devices that produce formed staples having different lengths

A surgical stapling device that comprises an end effector. According to various embodiments, the end effector comprises a circular anvil having a staple forming surface and a plurality of staples facing the staple forming surface of the anvil. The end effector also comprises a staple driver assembly comprising a plurality of staple drivers. Each staple driver supports one of the plurality of staples and is configured such that, when the staple driver assembly is actuated, each staple driver drives the staple into the staple forming surface of the anvil. A first quantity of the plurality of staple drivers has a first height and a second quantity of the plurality of staple drivers has a second height, wherein the first height is less than the second height.

Surgical stapling device with staple driver that supports multiple wire diameter staples

A staple cartridge for use with a surgical stapling device. The stapling device has an actuator that is selectively actuatable in an axial direction and an anvil that is moveable between open and closed positions. The staple cartridge comprises a plurality of staples and a first plurality of staple drivers. Each staple driver has an upper staple supporting surface for supporting one of the staples such that, when actuated, each staple driver drives the staple into the anvil. The upper staple supporting surface supports staples of different wire diameters in an upright position.

Surgical stapling device with staple drivers of different height

A surgical stapling device comprising an end effector. According to various embodiments, the end effector comprises an anvil having a staple forming surface and a plurality of staples facing the staple forming surface of the anvil. The end effector also comprises a plurality of staple drivers moveable supported within the staple cartridge. Each staple driver is in contact with one of the plurality of staples such that when the staple drivers are actuated, the plurality of staples are formed against the staple forming surface of the anvil. A first quantity of the staple drivers have a first height and a second quantity of the staple drivers have a second height, wherein the first height is less than the second height such that the staples driven by the first quantity of staple drivers have a longer formed length than the staples driven by the second quantity of staple drivers.

Surgical stapling device with anvil having staple forming pockets of varying depths

A surgical stapling device. The device comprises an end effector that comprises an anvil having a staple forming surface defining a plurality of staple forming pockets. A first quantity of the plurality of staple forming pockets has a first depth and a second quantity of the plurality of staple forming pockets has a second depth. The first depth is greater than the second depth.

Robotic catheter system and methods

A method for performing an interventional procedure using a robotically controlled guide instrument coupled to an instrument drive assembly, includes manipulating a user interface of a master controller to actuate the drive assembly and thereby position a distal portion of the guide instrument at an interventional procedure site in a patient's body; and providing on a first display a graphically rendered image of the distal portion of the guide instrument overlaying an image of the interventional procedure site, wherein manipulation of the user interface causes a corresponding movement of the instrument model relative to the image in the first display.

Methods and servers for establishing a connection between a client system and a virtual machine executing in a terminal services session and hosting a requested computing environment

A method for providing access to a computing environment includes the step of receiving a request from a client system for an enumeration of available computing environments. Collected data regarding available computing environments are accessed. Accessed data are transmitted to a client system, the accessed data indicating to the client system each computing environment available to a user of the client system. A request is received from the client system to access one of the computing environments. A connection is established between the client system and a virtual machine hosting the requested computing environment via a terminal services session, the virtual machine executed by a hypervisor executing in the terminal services session provided by an operating system executing on one of a plurality of execution machines.

Intragastric device for treating obesity

An intragastric device generally comprises a strip digestive-resistant mesh material that is operable between a first configuration and a second configuration. The first configuration is sufficiently small to permit introduction of the digestive-resistant mesh material into a gastric lumen of the mammal. The second configuration is sufficiently large to prevent the digestive-resistant mesh material from passing through the mammals pylorus, thereby permitting the mesh member to act as an artificial bezoar. Methods and devices for delivering the mesh member are also provided, including a pusher that is operable to engage and disengage the mesh member for delivery through the gastric lumen via a delivery sheath.

Medical devices with enhanced ultrasonic visibilty

A medical device having enhanced ultrasonic visibility is provided. The device permits localized drug delivery, probe positioning, fluid drainage, biopsy, or ultrasound pulse delivery, through the real-time ultrasound monitoring of the needle tip position within a patient. The device permits controlled dispersion of a drug into solid tissue, the lodging of particles into solid tissue, and drug delivery into specific blood vessels. As a needle is inserted, a fluid that contrasts echogenically with the organ environment is injected into the patient. The fluid travels a brief distance before being slowed and stopped by the patient's tissue and this fluid flow will be detectable by ultrasound. The needle position during insertion will be monitored using ultrasound until it is at the desired point of action. A therapeutic drug is then delivered or a probe inserted
