Publication number: 20240090898Abstract: Devices, methods, and systems for treating an ulcer or skin defect are disclosed. First and second base panels of a closure device are adhered to first and second sides of the ulcer or skin defect, respectively. Lateral ties couple the first and second base panels together and provide a predetermined separation distance or lateral gap between the inner edges of the panel. The predetermined separation distance or lateral gap is sufficient to treat the most common sized ulcers or skin defects, for example, accommodating an ulcer or skin defect with a minor axis of at most 50 mm. The lateral ties have their ends fixed to one panel and their opposite ends adjustably and reversibly attached to the other panel so that the separation distance can be reduced or adjusted to provide a lateral compressive force to the ulcer or skin defect, thereby promoting healing.Type: ApplicationFiled: November 21, 2023Publication date: March 21, 2024Inventors: Amir Belson, Kei Ichiryu, Daren Stewart, Eric Storne

Patent number: 7773541Abstract: If a selected packet switch connected to a neighboring packet switch makes first information identifying the neighboring packet switch available, element managers and processes retrieve the first information from the selected packet switch. The first information is derived by the selected packet switch from communication via a first protocol between the selected packet switch and the neighboring packet switch. If the first information is not available to the element manager and if the selected packet switch makes second information identifying the neighboring packet switch available to the element manager, the element managers and processes retrieve the second information from the selected packet switch. The second information is derived from communication via a second protocol between the selected packet switch and the neighboring packet switch and the first and second protocols are different protocols.Type: GrantFiled: June 29, 2007Date of Patent: August 10, 2010Assignee: World Wide Packets, Inc.Inventors: Eric Stewart Davison, K.
