20080312546 | Systems and Methods for Needle Access to an Intervertebral Disc - A catheter with a balloon anchor may be sized to fit through an inner needle and introduced into the patient through the needle. The inner needle may comprise an atraumatic needle with a side port and/or a blunt tip. The catheter may include a radiopaque coil disposed over the distal portion of the catheter body to assist with catheter placement when viewed with fluoroscopy and/or x-ray. The distal portion of the catheter can be very flexible. A balloon inflation tube may terminate proximal to a proximal end of the expandable balloon anchor such that the distal portion of catheter can be flexible. This termination of the inflation tube may also position the inflation tube away from the annulus and nerve roots, so as to avoid irritation of the annulus and rubbing of the nerve roots that may potentially obscure FAD test results. | 12-18-2008 |

20080312637 | Device and Methods for Introducing a Catheter into an Intervertebral Disc - A system includes components that allow the user to select how to perform disc diagnosis with the components of the system. The system components include a FAD catheter, a guidewire and stylet, in which both the guidewire and stylet are compatible with the catheter. The user may select to insert the catheter into the disc with a stylet included in the system. The user may also select to insert the catheter into the disc with the guidewire included in the system, for example after the guidewire has been placed with a rigid needle. | 12-18-2008 |
20090213867 | BLADE ROUTER WITH NAT SUPPORT - A blade router for increased interface scalability is provided. The blade router may address interface scalability by having each of the linecards manage its interfaces locally and may use the concept of virtual and local interfaces for intelligent forwarding. The blade router may appear as a single router from the customer perspective during configuration. For some embodiments, two virtual interfaces may be used, one for regular interface traffic and another for Network Address Translation (NAT)-enabled interface traffic. | 08-27-2009 |
20090213869 | BLADE SWITCH - A blade switch for increased interface scalability is provided. The blade switch may address interface scalability by having each of the switch linecards manage its interfaces locally and may use the concept of virtual and local interfaces for intelligent forwarding. The blade switch may appear as a single network switch having a single bridge ID from the network perspective during operation and from the customer perspective during configuration. | 08-27-2009 |
20100027420 | Dynamic distribution of virtual machines in a communication network - In one embodiment, a method generally includes monitoring network traffic associated with a first network device comprising at least one of a plurality of virtual machines and determining if a parameter exceeds a predefined threshold at the first network device. If the parameter exceeds the predefined threshold, one of the virtual machines is selected to move to a second network device, the second network device selected based on network information, and the virtual machine is moved. An apparatus for resource allocation is also disclosed. | 02-04-2010 |
20100214949 | Distributed data center access switch - In one embodiment, an apparatus includes a processor configured for operation in a control plane in a distributed virtual switch in communication with a plurality of virtual machines each having a virtual interface. The processor is operable to identify other control planes in the distributed virtual switch, assign a virtual interface identifier to one of the virtual interfaces, receive a configuration for the virtual interface, and share the configuration with the other control planes in the distributed virtual switch. The virtual interface identifier provides a unique identifier for the virtual interface across all of the control planes. The apparatus further includes memory for storing the configuration of the virtual interface. A method for operating a network device associated with a control in the distributed virtual switch is also disclosed. | 08-26-2010 |
