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
