Publication number: 20230277385Abstract: The disclosed medical dressing includes a dressing body with an overlying carrier system that is releasably secured to the dressing body. The carrier has a perimeter carrier portion overlying the perimeter of the dressing body and a central carrier portion overlying some, but not all, of a central area of the dressing body. This carrier construction allows for better handling of the medical dressing during application by giving both stability in some areas and stretching and flexibly in areas without the carrier.Type: ApplicationFiled: July 14, 2021Publication date: September 7, 2023Inventors: Guido Hitschmann, Benjamin Vollmann, Richard L.
