Reduced-pressure medical dressings, systems, and methods involve a dressing with a first barrier layer that desolidifies when exposed to a fluid—typically a liquid—to form a treatment aperture in the first barrier that is used to deliver reduced pressure to a tissue site. The first barrier layer is formed from a desolidifying material. The system includes a drape covering a second surface of a manifold and a portion of the patient's epidermis to provide a substantially sealed space containing a manifold and the first barrier layer. Other systems, dressings, and methods are also disclosed.

1. A system for providing reduced-pressure therapy to a tissue site, the system comprising: a manifold configured to be disposed over the tissue site and overlay intact epidermis surrounding the tissue site;a barrier layer covering at least a portion of the manifold, the barrier layer having a smooth surface configured to abut the intact epidermis surrounding the tissue site, the barrier layer comprising: a first portion adapted to desolidify in a presence of fluid to form a treatment aperture coextensive with the tissue site, wherein the treatment aperture facilitates fluid communication between the manifold and the tissue site, anda second portion adapted to separate the manifold from epidermis adjacent to the tissue site and remain intact when reduced pressure is applied to the tissue site; anda drape adapted to cover the manifold to provide a substantially sealed space containing the manifold and the barrier layer. 2. The system of claim 1, wherein the barrier layer is a first barrier layer, wherein the system further comprises a second barrier layer disposed adjacent to the manifold opposite the first barrier layer, and wherein at least a portion of the second barrier layer comprises a desolidifying material. 3. The system of claim 1, wherein the barrier layer is a first barrier layer, wherein the system further comprises a second barrier layer disposed adjacent to the manifold opposite the first barrier layer, and wherein at least a portion of the second barrier layer comprises a desolidifying material adapted to desolidify at a faster rate than the first portion of first barrier layer. 4. The system of claim 1, further comprising a plurality of perforations disposed through the barrier layer. 5. The system of claim 1, wherein the barrier layer is a first barrier layer, wherein the system further comprises a second barrier layer disposed adjacent to the manifold opposite the first barrier layer, wherein at least a portion of the second barrier layer comprises a desolidifying material, and wherein the first barrier layer and the second barrier layer each have a plurality of perforations. 6. The system of claim 1, wherein the barrier layer is a first barrier layer, wherein the system further comprises a second barrier layer disposed adjacent to the manifold opposite the first barrier layer, wherein at least a portion of the second barrier layer comprises a desolidifying material, wherein the first barrier layer and the second barrier layer each comprises a plurality of perforations, and wherein a perforation density of the second barrier layer has a higher perforation density than a perforation density of the first barrier layer. 7. The system of claim 1, wherein the barrier layer is a first barrier layer, wherein the system further comprises a second barrier layer disposed adjacent to the manifold opposite the first barrier layer, wherein at least a portion of the second barrier layer comprises a desolidifying material, wherein the first barrier layer has a first flow rate, and wherein the second barrier layer has a second flow rate. 8. The system of claim 1, wherein the barrier layer is a first barrier layer, wherein the system further comprises a second barrier layer disposed adjacent to the manifold opposite the first barrier layer, wherein at least a portion of the second barrier layer comprises a desolidifying material, wherein the first barrier layer has a first flow rate, wherein the second barrier layer has a second flow rate, and wherein the second flow rate is greater than the first flow rate. 9. The system of claim 1, further comprising: a connector coupled adjacent to an opening in the drape;a reduced-pressure source adapted to provide reduced pressure; anda conduit fluidly coupling the connector and the reduced-pressure source to supply reduced pressure to the substantially sealed space. 10. The system of claim 1, wherein the fluid is a liquid. 11. A dressing for providing reduced-pressure therapy to a tissue site, the dressing comprising: a manifold configured to be disposed over the tissue site and overlay intact epidermis surrounding the tissue site; anda barrier layer covering at least a portion of the manifold, the barrier layer having a smooth surface configured to abut the intact epidermis surrounding the tissue site, the barrier layer comprising: a first portion adapted to desolidify in a presence of fluid to form a treatment aperture coextensive with the tissue site, wherein the treatment aperture facilitates fluid communication between the manifold and the tissue site, anda second portion adapted to separate the manifold from epidermis adjacent the tissue site, and remain intact in a presence of reduced pressure. 12. The dressing of claim 11, wherein the barrier layer is a first barrier layer, wherein the dressing further comprises a second barrier layer disposed adjacent to the manifold opposite the first barrier layer, and wherein at least a portion of the second barrier layer comprises a desolidifying material. 13. The dressing of claim 11, wherein the barrier layer is a first barrier layer, wherein the dressing further comprises a second barrier layer disposed adjacent to the manifold opposite the first barrier layer, and wherein at least a portion of the second barrier layer comprises a desolidifying material adapted to desolidify at a faster rate than the first material of the first barrier layer. 14. The dressing of claim 11, further comprising a plurality of perforations through the barrier layer. 15. The dressing of claim 11, wherein the barrier layer is a first barrier layer, wherein the dressing further comprises a second barrier layer disposed adjacent to the manifold opposite the first barrier layer, wherein at least a portion of the second barrier layer comprises a desolidifying material, and wherein the first barrier layer and the second barrier layer each have a plurality of perforations. 16. The dressing of claim 11, wherein the barrier layer is a first barrier layer, wherein the dressing further comprises a second barrier layer disposed adjacent to the manifold opposite the first barrier layer, wherein at least a portion of the second barrier layer comprises a desolidifying material, wherein the first barrier layer and the second barrier layer each have a plurality of perforations, wherein a perforation density of the second barrier layer has a higher perforation density than a perforation density of the first barrier layer. 17. The dressing of claim 11, wherein the barrier layer is a first barrier layer, wherein the dressing further comprises a second barrier layer disposed adjacent to the manifold opposite the first barrier layer, wherein at least a portion of the second barrier layer comprises a desolidifying material, wherein the first barrier layer has a first flow rate, and wherein the second barrier layer has a second flow rate. 18.
