Abstract
In an initial configuration a device comprises a casing containing: a plurality of beads, a rupturable first container containing one or more isocyanates and a rupturable second container containing one or more polyols, wherein in the final configuration the casing is substantially filled by a polyurethane in which the plurality of beads are embedded. In an intermediate configuration the device is transformed from the initial configuration to a 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 device may be molded as the polyurethane is formed in the casing.
