Abstract: Blood vessels and other body lumens are stented using multiple, discreet stent structures. Stent structures may be balloon expandable or self-expanding and are delivered by a delivery catheter which is repositioned to spaced-apart delivery sights. By coating the stents with particular biologically active substances, hyperplasia within and between the implanted stents can be inhibited. An exemplary delivery catheter comprises a catheter body having both a pusher rod for advancing the stents relative to a sheath and a reciprocatable delivery catheter for implanting the stents.

Abstract: A liner is advanced through a narrowed region in a vessel such as the internal carotid artery. The liner is advanced through the narrowed region in a collapsed position. A stent is then advanced through the liner and expanded to open the narrowed region. The liner may also have an anchor which expands an end of the liner before the stent is introduced.

Abstract: A protective cover for arterial or a similar needle is effective for covering the needle tip and also can be retracted along the needle shaft to uncover and reopen the needle. The cover has a sheath section, whose movement along the shaft is controlled by an actuator section. The sheath section has two through channels and the actuator section has an actuator element with a corresponding channel opening. In the open position, that is when the needle tip is exposed, the channels within the sheath section and the channel opening of the actuator element are aligned and the needle shaft extends through the channels and the opening. To enclose the needle tip, the cover is slid along the needle shaft to the tip, so that the actuator section is slid off the shaft. At this point, a spring within the actuator section compels the actuator element upward, effectively locking the tip within the cover.

Abstract: Devices, systems and methods develop static and/or kinetic and/or pressure forces to fixate or brace tissue in targeted pharyngeal structures and individual anatomic components within the pharyngeal conduit.

Abstract: Methods and devices for harvesting veins from the body. The methods and devices allow vein harvesting using laparoscopic procedures. A working space is created over the vein using standard laparoscopic procedures and a side-hooked wire is inserted into the working space and twisted to insert the side-hook under the vein. The wire is then pulled or drawn along the vein to separate the vein from the surrounding tissue. In an alternative embodiment, vein separation is accomplished by threading a soft rubber tube under the vein, grasping the ends of the tube so as to surround the vein, and then pulling the tube along the vein. In other embodiments, the working space is created with everting balloons.

Abstract: Blood vessels and other body lumens are stented using multiple, discreet stent structures, or continuous coiled or mesh stent structures. Stent structures may be balloon expandable or self-expanding and are delivered by a delivery catheter which is repositioned to spaced-apart delivery sights. By coating the stents with particular biologically active substances, hyperplasia within and between the implanted stents can be inhibited. An exemplary delivery catheter comprises a catheter body having a deployment mechanism for deploying one or more stents of selectable length into the vessel.

Abstract: A method for use in a computer system for displaying a containment group such as file folder hierarchy. The method displays a direct containment hierarchy for the selected containment group or file folder, and also displays a list of contents of the selected containment group or file folder. A direct containment hierarchy displays only file folders or containment groups which directly or indirectly contain the selected containment group or file folder. In this manner a large number of file folders or containment groups which do not ultimately contain the selected file folder or containment group are not displayed, thereby simplifying the display, and ensuring that the entire direct containment hierarchy can be shown on a single display screen without the need for scrolling in order to obtain or ascertain the context of the given file folder or containment group.

Abstract: The present invention relates to a graphical user interface (GUI) for displaying historical and current performance information for a route in a communications network, the route having several paths between two end points. Performance data from the network is collected and processed to generate route and path performance data. The processed data is stored in a database. The GUI is embodied in a network management device which draws upon information stored in the database. In a preferred embodiment, the GUI displays a route panel showing the structure of the route, a timebar showing the time period for which information is displayed, a paths panel showing information about each path in a tabular format, a selected paths panel showing information about selected paths in a tabular format, and a performance panel showing performance data in a graph.

Abstract: Network management can be made more efficient by using a graphical user interface that is clear and concise in what network information is identified and subsequently displayed. One key to improving graphical user interfaces is the categorizing of network entities into a series of attribute layers that define different features of the network entities. For instance, a layer of attributes may include geographical regions, services, customers, or types of network entities. By selecting a base view from the group of geographical regions and then network features for filtering operations from one or more of the other attribute layers, the network entities defined by the selected network features can be identified and isolated with all other irrelevant network entities being filtered out. The advantages to this graphical user interface is especially evident when considering the case that a specific customer, service, or network entity requires special attention.

Abstract: A network management method and system for managing a network in which routes between pairs of end points take different paths is provided. To begin, device level status and performance information is collected from the network and transformed into path and route information. Next, from the path and route information parameters which characterize the state of each of the routes are computed. Next, the parameters of each of the routes are displayed graphically. This allows a user to obtain a quick visual identification of the state of all of the routes in the network individually and in relation to one another. The invention also provides a network management graphical user interface method in which a 3-D representation of three axes is displayed. Each axis pertaining to a respective one of three route parameters. On these three axes, for each route a parameter point representing the routes parameters is displayed as a function of time.

Abstract: The present invention provides a branching endoluminal prosthesis for use in branching body lumen systems which includes a trunk lumen and first and second branch lumens. The prostheses comprises a radially expandable tubular trunk portion having a prosthetic trunk lumen, and radially expandable tubular first and second branch portions with first and second prosthetic branch lumens, respectively. A radially expandable tubular Y-connector portion provides fluid communication between the prosthetic trunk lumen and the first and second prosthetic branch lumens.
