## Abstract

A permeable layer associated relative to a phase change material associated relative to a securing fabric layer. The permeable layer retains a therapeutic or cosmetic agent to be transferred, in whole or in part, to the user's skin. The phase change material may be dissolved within a thermoplastic matrix or situated within a suitable container. This invention provides the novelty of a phase change material, coupled with a permeable layer and a fabric layer, which work in conjunction with a therapeutic or cosmetic agent.

## Claims

### Claim 1

A thermally assisted therapeutic aid comprising:
a single, contiguous, material layer, wherein the material layer is composed of an open cell foam, felt, knit, weave of hydrophobic or amphiphilic or hydrophilic fibers, non-woven fabric or their combinations thereof comprising a therapeutic agent homogeneously dissolved in the material layer;
a phase change material layer comprising a phase change material; and
a fabric layer configured to secure the aid relative to an appendage.

### Claim 2 (depends on 1)

The thermally assisted therapeutic aid of claim 1 wherein the phase change material is situated within a container.

### Claim 3 (depends on 1)

The thermally assisted therapeutic aid of claim 1 wherein the phase change material is bonded to a container that contains the phase change material.

### Claim 4 (depends on 1)

The thermally assisted therapeutic aid of claim 1 wherein the phase change material is situated within an elastomeric matrix.

### Claim 5 (depends on 1)

The thermally assisted therapeutic aid of claim 1 wherein the phase change material is a linear alpha olefin having a melting point in the range of 0° C. to 20° C.

### Claim 6 (depends on 1)

The thermally assisted therapeutic aid of claim 1 wherein the phase change material includes a hydrocarbon wax having a melting point in the range of 45° C. to 65° C.

### Claim 7 (depends on 1)

The thermally assisted therapeutic aid of claim 1 wherein the phase change material layer is bonded relative to the material layer by means of adhesives, casting, molding, or heat treatments.
