Abstract
A device for a medical or cosmetic treatment based on heat is provided. The device includes an impermeable backing layer and an adhesive layer in contact with the backing layer. The device also includes an alkali metal selected from a single, free alkali metal and an alloy alkali metals, the alkali metal in contact with at least a portion of the adhesive layer to define a treatment region. The device also includes a release liner in contact with the adhesive layer and the treatment region. A heat delivery system or kit including the device and a method for its use are also provided.
Claims26
A device, comprising:
- a backing layer having opposing sides, the backing layer impermeable to water, oxygen, or both;
- an adhesive layer in contact with a first side of the backing layer;
- an alkali metal selected from a single alkali metal and an alloy of multiple alkali metals, the alkali metal in contact with at least a portion of the adhesive layer on the first side of the backing layer to define a treatment region, wherein the alkali metal is in the form of a foil having a thickness of between about 0.0254 mm and 2.54 mm (0.001 in to 0.10 in) and is configured to contact a treatment site to generate heat;
- and
- a release liner in contact with the adhesive layer and the treatment region.
A device, comprising:
- an impermeable, backing layer;
- an adhesive layer in contact with the backing layer;
- an alkali metal selected from a single alkali metal and an alloy of multiple alkali metals, the alkali metal in contact with at least a portion of the adhesive layer to define a treatment region;
- and
- a release liner in contact with the adhesive layer and the treatment region,
- wherein the backing layer has opposing sides, and the adhesive layer is coated on one side of the backing layer,
- wherein the adhesive layer is a pressure sensitive adhesive layer, and
- wherein the alkali metal is on or embedded in an adhesive matrix that is in contact with the pressure-sensitive layer.
