20080298373 | Secure VLANs - A VLAN is implemented with a logical hub and spoke topology that obviates local switching. Member devices are connected to a hub device such as a router via intermediate devices such as Layer 2 switches that support individual IP subnets within the VLAN. The Layer 2 switch does not allow bridging, so there is no IP subnet broadcast domain. Further, the Layer 2 switch implements only a single logical broadcast uplink port which is connected to the router. The Layer 2 switch also implements only point-to-point downlink ports, i.e., to individual member devices. Consequently, all traffic is forced to flow through the router, e.g., broadcast traffic, multicast traffic and traffic of unknown destination received by the Layer 2 switch from a member device is only flooded to the router, and the router performs intra-subnet routing in addition to routing between subnets and between VLANs. The router subjects all traffic to security measures and provide services including packet inspection, firewall, policing, metering, accounting, anti-virus, marking, filtering and encryption, and thereby reduce or eliminate the drawbacks associated with local switching. | 12-04-2008 |
20120155259 | ACCESS CATEGORY ENFORCEMENT IN WIRELESS LOCAL AREA NETWORKS - The present invention provides a control function in an access point, switch, or like node on a wireless local area network. The control function operates to ensure frames transmitted by a user terminal are transmitted using an appropriate transmission priority scheme. The control function will assist and provide an appropriate priority level to the user terminal. Frames transmitted from the user terminal are passed through the control function, which will analyze priority level information provided in the frames to determine if the frames were transmitted using the appropriate transmission priority scheme. An enforcement action may be taken in response to identifying frames that were not transmitted using the appropriate transmission priority scheme. | 06-21-2012 |

20090248059 | Embolectomy Catheter - The device subject of this disclosure is a catheter conveying inflatable components that control the opening and closing of a net component. The catheter is maneuvered through the tortuous and stenotic cerebral circulatory system to an embolism. The positioning of the catheter may be guided by radio opaque markers. The inflatable component carrying the net is placed into the embolism. The balloons are inflated thereby expanding the net into the embolism. The limit of expansion is controlled by the dimensions of the net. As the net expands, fenestrations or the spacing of a wire mesh comprising the net enlarge, thereby allowing the embolism to become entrapped within the net. The balloons are deflated thereby enclosing the embolism within the net. The device can be retract into a guide catheter and withdrawn from the circulatory system. | 10-01-2009 |
20090254101 | Suturing Device for Anastomisis of Lumens - A surgical device that includes an outer hollow body and an inner hollow body. The inner hollow body is slidably disposed within said outer hollow body and the inner hollow body includes at least two hollow arms located at the distal end of the inner hollow body. An inflatable member is rotatably attached to each hollow arm of the inner hollow body. At least a pair of suture rings are rotatably coupled to the outer hollow body wherein the suture rings are in parallel to each other and are coupled to each other by a plurality of suture clips. | 10-08-2009 |
20090299326 | ENDOVASCULAR ANEURYSM TREATMENT DEVICE AND METHOD - An self-expanding frame is mounted on the distal end of a shaft. The frame is sized and configured so that it can be inserted into the cavity of an aneurysm. Suction is applied to the interior of the aneurysm through the shaft or through another catheter, and the wall of the aneurysm is collapsed onto the exterior surface of the frame. The frame is then collapsed upon further suction being applied to the interior of the aneurysm, which collapses the aneurysm wall with it. The frame folds down on itself, carrying with it the aneurysm wall. The frame is detachable from the shaft and can be left in the collapsed aneurysm. | 12-03-2009 |
20100198251 | Aneurysm Sealing Device - A device useful for treating an aneurysm having a neck comprises a first inflatable disc and a second inflatable disc, said second inflatable disc being adjacent to said first inflatable disc and in fluid communication therewith. The inflatable discs are sized and constructed such that when the inflatable discs are inflated, the aneurysm neck is engaged there between. The inflatable discs may include at least one wall that is substantially inelastic and may include an internal member limiting expansion of the inflatable disc in a direction parallel to the device axis. The inflatable discs may have an aspect ratio greater than 3. | 08-05-2010 |
