Abstract:
1. A method of operation of a topical application device for topical application of a therapeutic treatment including vasodilation, comprising the steps of: providing a heat generating layer; the heat generating layer including a metallised substrate of porous fabric having a plurality of components, selected from the group consisting of yarns, fibers and threads, each encapsulated in metal wherein the metal on the metallised substrate of porous fabric is photochemically etched by selectively etching out metal encapsulated about the plurality of components of metallised substrate of porous fabric to create at least one electrical heat generating circuit with first portions of the porous fabric being encapsulated with metal and second portions of the porous fabric not being encapsulated with metal; heat being generated by the first portions of the porous fabric; providing a contact layer having at least one therapeutic agent therein for delivery to a subject; adhering the heat generating layer to the contact layer; running electricity through the at least one electrical heat generating circuit to provide heat output; and delivering the at least one therapeutic agent to the subject upon providing the heat output to the contact layer.
