Abstract

Described herein are adhesive support devices, which may include adhesive medical devices. In particular, three-dimensional adhesive medical devices from a single layer of material, typically by stamping or pressing (including cold pressing) a sheet of the material to form rigid and complex 3D shapes capable of use for a variety of medical and non-medical purposes. These adhesive support devices typically also include an adhesive material allowing the device to be attached to a subject'"'"'s skin and/or mounted on a surface (e.g., wall, etc.). In particular, described herein are methods of manufacturing, assembling, and using adhesive support devices.
