409results about How to "Prevent travel" patented technology

Various forms of surgical instruments are disclosed. In various embodiments, the instrument includes a cartridge supporting assembly for operably supporting a staple cartridge therein. The cartridge supporting assembly may be responsive to firing and retraction motions applied thereto from a firing assembly. An anvil may be operably coupled to an anvil closure assembly. The anvil closure assembly may be constructed to selectively move the anvil in a proximal direction toward the cartridge supporting assembly to enable a portion of tissue to be clamped between a cartridge supported by the cartridge supporting assembly and the anvil under a predetermined amount of compression. The device may further include a compression limiting assembly that interacts with the anvil closure assembly to prevent further travel of the anvil in the proximal direction toward the cartridge supporting assembly when the predetermined amount of compression has been attained.

A hose direct cannister lid includes a port that accepts a hose connected to a source of vacuum in order to evacuate a cannister to which the lid is connected. The hose direct cannister lid includes a first valve for exposing the cannister to the source of vacuum when the vacuum hose is secured to the lid, and wherein the first valve closes when the source of vacuum is removed in order to seal the lid and cannister from ambient. The hose direct cannister includes a second valve used to break the vacuum and expose the interior of the cannister to ambient.

A medical delivery device comprising an elongate body having a plunger slidably and sealingly engaged to form a cavity to receive fluid materials and a first outlet disposed at an end of said body and has a male luer end portion and a valve assembly is disposed within the first outlet. The valve assembly has a valve means movable between an open position and a closed position and biasing means for biasing the valve means to a closed position. Actuating means are disposed within the male luer end portion and coupled to the valve means such that the valve means is movable to an open position when a female luer end portion of a medical accessory is coupled with the male luer end portion. A second outlet is disposed at the same end as the first outlet for controlling the exchange of gases from the environment to said cavity under the action of the plunger. Lastly, a third outlet is disposed at the same end as the first outlet for controlling the exchange of gases from the cavity to the environment under the action of the plunger.

A method and apparatus for introducing a stent into a region of a major blood vessel within the human body in a manner which substantially reduces the risk of embolic material escaping to the vessel and causing a blockage at a downstream location. Additionally, the apparatus includes a uniquely designed stent delivery catheter having a central lumen through which a guide wire travels, the central lumen being provided with a valve means that is operable by the guide wire and when moved into a closed position by withdrawal of the guide wire, functions to prevent the flow of loose debris toward the proximal end of the catheter.

Apparatus is provided including an assembly (22) and a control unit (36). The assembly (22) includes a housing (34) configured to be applied to a nerve (20) of a subject, and at least one cathode (30) and at least one Peltier cooler (32), which are fixed to the housing (34). The control unit (36) is configured to drive the cathode (30) to apply an activating current to the nerve (20) that generates action potentials traveling in first and second directions (38 and 40) in the nerve (20), and the Peltier cooler (32) to cool the nerve (20) sufficiently to block propagation of at least a portion of the cathode-generated action potentials traveling in the second direction (40). Other embodiments are also described.

An animal guard with a multitude of rotatable elements that can be securely mounted on a generally vertical or horizontal structure is disclosed. The rotatable elements may be of varying shapes and are designed to provide an unsteady footing for animals attempting to cross the object to continue travel along the structure. In accordance with one embodiment, the animal guard is configured to surround a vertically-extending structure. A series of hollow rotatable elements, or "spinners", are provided with a hole formed at opposing longitudinal ends. The spinners are bifurcated into two generally equal halves that attach together. A guard plate is mounted to surround the structure and has a series of cross arm brackets which extend through the end holes of the spinners to serve as end axles for rotation and to position the spinners around the circumference of the structure. A support means secures the location of the guard plate and spinners and couples the guard plate to the structure. Another embodiment of the animal guard inhibits animal passage along generally horizontal structures, such as cables, lines and wires. A series of hollow rotatable spinners are provided with a hole formed at opposing longitudinal ends. The spinners are bifurcated into two generally equal halves that attach together to secure the spinners around a horizontal structure. End shields are configured with a hole extending laterally therethrough to mount the end shields onto an end section of the spinners; one end shield is positioned at each of the opposite ends of a series of spinners. A gripping means is positioned adjacent to the end shields at the opposite end of the series of spinners to grip the horizontal structure and hold the end shields and spinners at fixed positions horizontally along the line.
