Patent number: 12220491Abstract: An embodiment includes a wound dressing comprising: a shape memory polymer (SMP) foam, including open cells, having first and second states; and a hydrogel (HG) included within the cells; wherein (a) in a first position a composite, including the SMP foam and the HG, is configured to be located proximate a hemorrhagic tissue with the SMP foam in the first state; (b) in a second position the composite is configured to be expanded to the second state against the hemorrhagic tissue when the SMP foam is plasticized at 37° C. depressing a glass transition temperature (Tg) of the SMP foam to below 25° C. Other embodiments are described herein.Type: GrantFiled: February 26, 2024Date of Patent: February 11, 2025Assignees: LAWRENCE LIVERMORE NATIONAL SECURITY, LLC, THE TEXAS A&M UNIVERSITY SYSTEMInventors: Duncan J.
