A releasable medical drape, and systems and methods having the same, includes at least a liquid-impermeable, vapor-permeable layer, a pressure-sensitive adhesive layer, and a soft-gel layer having a plurality of apertures. The soft-gel layer is configured to be disposed adjacent to a tissue site. A portion of the pressure-sensitive adhesive layer extends through the plurality of apertures in the soft-gel layer to contact the tissue site. The soft-gel layer forms a good seal with the tissue site and the pressure-sensitive adhesive layer extending through the plurality of apertures forms a firm—but releasable—coupling with the tissue site.

1. A system for treating a tissue site with reduced pressure, the system comprising: a manifold adapted to be disposed proximate to the tissue site for distributing reduced pressure;a releasable medical drape adapted to be disposed over the manifold and adapted to form a sealed space that contains the manifold;a reduced-pressure source adapted to be fluidly coupled to the manifold; andwherein the releasable medical drape comprises: a liquid-impermeable, vapor-permeable layer having a first side and a second side;a pressure-sensitive adhesive layer having a first side and a second side, wherein the first side of the pressure-sensitive adhesive layer is coupled to the second side of the liquid-impermeable, vapor-permeable layer;a soft-gel layer having a plurality of apertures, a first side, and a second side, wherein the first side of the soft-gel layer is coupled to the second side of the pressure-sensitive adhesive layer; andwherein the pressure-sensitive adhesive layer is configured to extend at least partially through the plurality of apertures in the soft-gel layer in response to force applied to the first side of the liquid-impermeable, vapor-permeable layer. 2. The system of claim 1, wherein the soft-gel layer comprises silicone. 3. The system of claim 1, wherein the soft-gel layer comprises at least one of the following: silicone, hydrocolloid, hydrogel, polyurethane gel, and polyolefin gel. 4. The system of claim 1, wherein the pressure-sensitive adhesive layer comprises an acrylic adhesive. 5. The system of claim 1, the pressure-sensitive adhesive layer comprises at least one of the following: an acrylic adhesive and a tacky silicone adhesive. 6. The system of claim 1, wherein the liquid-impermeable, vapor-permeable layer comprises a polyurethane film having a moisture vapor transfer rate greater than or equal to about 300 g/m2/24 hrs. 7. The system of claim 1, wherein the liquid-impermeable, vapor-permeable layer comprises a polyurethane film having a thickness in a range of about 15 microns to about 50 microns. 8. The system of claim 1, wherein the apertures comprises one or more of the following shapes: circles, squares, stars, slits, ovals, polygons, complex curves, rectilinear shapes, and triangles. 9. The system of claim 1, wherein each aperture of the plurality of apertures has an average effective diameter in a range of about 6 mm to about 50 mm. 10. The system of claim 1, wherein the soft-gel layer comprises silicone having a thickness in a range of about 500 to about 1000 microns. 11. The system of claim 1, wherein the soft-gel layer comprises silicone having a hardness in a range of about 5 Shore OO and about 80 Shore OO. 12. The system of claim 1, wherein the pressure-sensitive adhesive layer has a coating weight between about 15 grams/m2 and about 70 grams/m2. 13. The system of claim 1, further comprising a first release liner having a first side and a second side, wherein the first side of the first release liner is proximate to the second side of the soft-gel layer. 14. The system of claim 1, wherein the pressure-sensitive adhesive layer comprises a patterned layer of a pressure-sensitive adhesive applied to the second side of the liquid-impermeable, vapor-permeable layer. 15. A releasable medical drape for providing a seal over a tissue site, the releasable medical drape comprising: a liquid-impermeable, vapor-permeable layer having a first side and a second side;a first plurality of strands substantially coated with a pressure-sensitive adhesive and wherein the first plurality of strands are coupled to the second side of the liquid-impermeable, vapor-permeable layer;a second plurality of strands substantially coated with a soft-gel and wherein the second plurality of strands is coupled at least in part to liquid-impermeable, vapor-permeable layer; andwherein the pressure-sensitive adhesive of the first plurality of strands is configured to extend at least partially beyond the second plurality of strands when a force is applied to the first side of the liquid-impermeable, vapor-permeable layer. 16. The releasable medical drape of claim 15, wherein the first plurality of strands forms a mesh layer. 17. The releasable medical drape of claim 15, wherein the second plurality of strands forms a mesh layer.
