  • Patent number: 9338059
    Abstract: Method and system for configuring a plurality of virtual networks using a plurality of physical resources of a network device is provided. A hierarchical data structure having a plurality of layers for representing an instance of the network device is generated. A first layer represents the plurality of virtual networks; a second layer represents a plurality of virtual network protocols that are used by the plurality of networks; and a third layer represent the physical resources that are used by the plurality of virtual networks for communicating with other devices. The plurality of virtual networks is validated by using the data structure to check if there is any conflict in using the selected physical resources.

  • Patent number: 9071544
    Abstract: A management request complying with a first protocol is generated by a management application executed by a computing system coupled to a network element. A processor executable agent encapsulates a management request using a second protocol. The encapsulated management request is transmitted using a third protocol via a link used by the computing system to send input/output requests for reading and writing data to a storage device. The management request is de-encapsulated to provide the management request complying with the first protocol to a management module of the network element. The management module of the network element prepares a response to the management request complying with the first protocol. A processor executable service at the network element encapsulates the response using the second protocol. The encapsulated response is transmitted to the computing system using the third protocol. The response complying with the first protocol is extracted from the encapsulated response.

  • Publication number: 20130006272
    Abstract: A sealing clip for sealing or holding punctures or openings in tissue closed is applied from the inner surface of the tissue. A delivery apparatus is used to releasably hold the clip in one configuration for introduction of the clip through the puncture or opening and expand the clip to a more open configuration for pulling the clip through the tissue as the delivery apparatus is retracted. Further retraction of the delivery apparatus causes the edges of the tissue surrounding the opening to move along the clip and come together after which the clip is released and closed to hold the tissue edges of the opening together. In the case where the clip has a memory set closed shape, the clip returns toward that shape after being released to hold the tissue edges of the opening together, thereby holding the opening closed.

  • Patent number: 8298251
    Abstract: A system for anastomosing a first tubular structure to a second tubular structure having an opening formed therein comprises a support device having a plurality of arms forming spaces therebetween and a plurality of piercing members slidably coupled to the arms. The support device piercing members have a retracted state and an extended state to support the first tubular structure thereon for placement within an opening in the second tubular structure to facilitate anastomosing the tubular structures together. The arms can be configured to urge the first tubular structure against the portion of the second tubular structure surrounding the opening to form a seal therebetween. According to one embodiment, a plurality of discrete fasteners are provided to pass through the support device spaces and the first and second tubular structures. In another embodiment, fasteners are integrated into the support device and releasably coupled thereto for delivery to the anastomosis site.

  • Patent number: 8211124
    Abstract: A sealing clip for sealing or holding punctures or openings in tissue closed is applied from the inner surface of the tissue. In one embodiment, the clip has piercing members for penetrating the tissue from an inner surface thereof adjacent the opening. A delivery apparatus is used to releasably hold the clip in one configuration for introduction of the clip through the puncture or opening and expand the clip to a more open configuration for pulling the clip through the tissue as the delivery apparatus is retracted. Further retraction of the delivery apparatus causes the edges of the tissue surrounding the opening to move along the clip and come together after which the clip is released and closed to hold the tissue edges of the opening together. In the case where the clip has a memory set closed shape, the clip returns toward that shape after being released to hold the tissue edges of the opening together, thereby holding the opening closed.

  • Publication number: 20110114246
    Abstract: A method and an apparatus for application of sealing or shim material to surfaces is provided. The materials are used in particular in the construction of aircraft and other vehicles. The materials are typically interposed in a joint between a vehicle structural element and a vehicle external surface forming component. The sealing materials are adherent. The apparatus of the invention includes a moveable arm carrying an end member having a curved surface. The arm applies the curves surface to a web of the sealing material so that the sealing material becomes wrapped around the curved surface. The arm is then moved to the location of the joint and the web of sealing or shim material is applied to the joint surface by causing or allowing the end member to roll of said surface.

  • Publication number: 20070260270
    Abstract: Cutter assemblies for use with cutter blades made of shape memory materials. The cutter blades may be deployed in the interior of an intervertebral disc space and rotated relative to a central axis of the cutter assembly to cut the material present for removal from the intervertebral disc space. Cutter blades with different attributes (such as throw length, cutter blade angle, type and location of blade edges) are adapted to achieve different objectives within the intervertebral disc space. Some cutter blades are adapted to promote bleeding of cartilage and vertebral body endplates and some cutter blades are adopted to avoid causing such bleeding. Closed loop cutter blades are described which have certain desirable attributes including the ability to remove the entire cutter blade from the intervertebral disc space after a break in the blade. Serration patterns are disclosed including a serration pattern that makes use of trapezoidal serrations.
