A cast

Abstract

A cast for casting over an object, wherein the cast comprises: a first layer composed of a breathable material for contacting an exterior surface of an object; and a second layer for acting as a support structure, wherein the second layer is activatable upon application of a stimulus to soften for self-moulding to conform to contours of the exterior surface of the object. In one embodiment, the cast is an orthopaedic cast. In one embodiment, the second layer comprises a shape-memory thermoplastic that is rigid at room temperature but softens when heated, for example, to a temperature of 55 degree Celsius or higher.
