Abstract: A releasable medical drape, and systems and methods having the same, includes at least a liquid-impermeable, vapor-permeable layer, a pressure-sensitive adhesive layer, and a soft-gel layer having a plurality of apertures. The soft-gel layer is configured to be disposed adjacent to a tissue site. A portion of the pressure-sensitive adhesive layer extends through the plurality of apertures in the soft-gel layer to contact the tissue site. The soft-gel layer forms a good seal with the tissue site and the pressure-sensitive adhesive layer extending through the plurality of apertures forms a firm—but releasable—coupling with the tissue site.

Abstract: In some embodiments, a dressing assembly may include a dressing bolster, an interface seal, and a base layer. The dressing bolster may include a first side, a second side, and a periphery. The interface seal may be coupled at the periphery of the dressing bolster. The base layer may include a base layer flange configured to be coupled to the dressing and to extend beyond the periphery of the dressing bolster. The dressing assembly may be suitable for treating a tissue site with reduced pressure and for creating an apposition force between a first portion of the tissue site and a second portion of the tissue site. Other systems, apparatus, and methods are disclosed.

Abstract: This disclosure describes devices, systems, and methods related to therapy devices including pumps that are operable in multiple operating modes. An exemplary wound therapy device includes a pump configured to be worn by a user and a controller coupled to the pump and configured to transition the pump from operating in a first operating mode to operating in a second operating mode responsive to a pressure of the wound therapy device satisfying a first pressure threshold. The first operating mode is associated with a first drive voltage that is different from a second drive voltage associated with the second operating mode.
