POSITION-RETAINING DEVICE
A device comprising a casing and having an initial configuration, an intermediate configuration, and a final configuration, wherein in the initial configuration the casing contains: a plurality of beads, a rupturable first container containing one or more isocyanates and a rupturable second container containing one or more polyols. In the final configuration the casing is substantially filled by a polyurethane in which the plurality of beads is embedded. In the intermediate configuration the device is transformed from the initial configuration to the final configuration by rupturing the first container and rupturing the second container so that the one or more isocyanates react with the one or more polyols in a reaction that forms the polyurethane. As the polyurethane is formed during the reaction the polyurethane surrounds the plurality of beads. The casing includes one or more vent tubes configured to allow gases formed by the reaction to escape the casing.

System for Forming a Rigid Support
The system invention describes a support and improved method of application and removal. The support, comprised of a network of flexible, non-porous, multi-lumen tubing interlaces at a plurality of junctions to form a lattice structure. Apertures designed to accommodate boney prominences also permit air or water to reach the skin underneath and encourage rapid fluid flow internally through the lattice. A hydrophobic, thermal-resistant, flowable padding layer is injected within a secondary lumen to the lattice structure, spanning its complete surface area. As a result, the breathability of the support is not affected by this padding layer because it mirrors the apertures of the lattice. At least one liquid is injected into the structure and configured to transform into a solid when acted on by an external mechanical stimulus.
