A surgical instrument particularly suited to endoscopic use articulates an end effector by including a laterally sliding member in a proximal portion of a shaft that pivots the end effector to a selected side. Differentially opposing actuating forces (e.g., hydraulic, fluidic, mechanical) act against the laterally sliding member without binding by incorporating guidance mechanisms between the laterally sliding member and a frame of the shaft. A locking member advantageously unlocks automatically as articulation is commanded by resists backdriving of the mechanism.

A method and apparatus for carrying our thermal ablation of target tissue is disclosed. The apparatus includes an RF ablation device having a multi-electrode electrode assembly designed to be deployed in target tissue, defining a selected-volume tissue region to be ablated, and having infusion channels for infusing a liquid into the target tissue during the ablation process. A control unit in the apparatus is operably connected to an RF energy source, for controlling the RF power level supplied to the electrodes, and to an infusion device, for controlling the rate of infusion of a liquid through the device into the tissue. During both electrode deployment and tissue ablation, impedance and or temperature measurements made within the tissue are used to control the RF source and infusion device, for optimizing the time and extent of tissue ablation.

The bypass network is designed to provide fast access and high quality streaming media services anywhere anytime. There are five major components including Peering Gateway, Content Locator, Edge Server, Gateway and Client. The whole bypass network is divided into number of self-managed sub-networks, which are referred as local networks in this document. Each local network contains Edge Servers, gateways, and a Content Locator. The Edge Servers serve as cache storage and streaming servers for the local network. The gateways provide a connection point for the client computers. Each local network is managed by a Content Locator. The Content Locator handles all client requests by communicating with the Peering Gateway and actual web sites, and makes the content available on local Edge Servers. The Content Locator also balances the load on each Edge Server by monitoring the workload on them. One embodiment is designed for home users whose home machine does not move around frequently. A second embodiment is designed for business users who travel around very often where the laptops would self-configure as a client of the network.

A surgical extractor for removing objects from a body including, for example, calculi, such as kidney stones and gall stones. The extractor includes a handle at a proximal end with a slider for operation by a physician. At the distal end the extractor includes a plurality of wires with each wire comprising a first portion having an individual strand and a second portion comprising a plurality of filaments. When a retaining sheath is retracted, the wires, formed of a shape memory material such as stainless steel, expand such that each of strands assume a spaced relationship to define a first section of a basket and the plurality of the filaments assume a spaced relationship to define a second section of the basket. The use of a basket formed by wires having a first section having an individual strand and a second section having the plurality of filaments promotes capture of objects within the body by having widely spaced wires in the first section, retention of such objects in the second section by multiplying the number of contacts with entrapped object, and improved selective release of such objects without any deleterious effect on the reliability or size of the extractor. Additionally, use of the basket enables improved dislodgment and capture of embedded or impacted objects.

The present invention is directed to an expandable spinal fusion intervertebral implant that provides for maintaining and creating lordosis in the human spine that can be filled with biologics while in situ to encourage spinal fusion. A threaded rod that traverses an insertion / injection handle can be rotated to operate a screw within the interbody cage that displaces opposing vertical tapped sliding wedges, causing them to converge towards each other. Such contact causes the operation of a horizontal wedge that acts as a lift to expand the interbody cage to one of various dimensions in a preferred range. At its desired expansion, the spinal fusion implant of the present invention is sized to fit within the disc space between two vertebral bodies and fill all voids left while the vertical and horizontal wedges operate within, due to the biologics being contained within the interbody cage.

Ordered binder document sections having different file formats stored within a binder file. The binder file maintains the order of binder document sections and the native file format of each section. The ordered sections can be viewed and edited through a viewport of a frame displayed by a binder program module. By selecting graphical images displayed in a selection area of the frame the content of a binder document section can be viewed and edited without viewing the content of other binder document sections. The graphical images can be icons or graphical images derived from the content of sections called thumbnail images. A thumbnail image can be derived from either the first page or from multiple pages of an individual section. The binder program module can also dispatch the underlying application program modules that created each binder document section to print, spell check, and grammar check the binder document sections as a single data processing task. In this manner, selected sections of a binder document can be printed as a single consecutively printed document without having other print jobs interrupting or intervening between printed sections of the binder document.
