1. A patterned neo-epithelium dressing for treating an epithelial tissue site having granulation tissue, the patterned neo-epithelium dressing comprising:
- an interface member having a first side and a second, patient-facing side for placing proximate to the granulation tissue; and
a plurality of three-dimensional features patterned after at least one of an epithelial and endothelial lining having an intact analogous skin pattern and formed on the second, patient-facing side of the interface member;
wherein the interface member is not adherent to the epithelial tissue site so as to be removable from the epithelial tissue site after the treating.

Abstract
Systems, methods, and apparatuses are presented that involve forming patterns on neo-epithelium that allow increased functionality and may more nearly resemble the original epithelium. In one instance, a patterned neo-epithelium dressing for treating a tissue site having granulation tissue includes an interface member for placing proximate the granulation tissue and a plurality of three-dimensional features formed on a second, patient-facing side of the interface member. Other systems, methods, and apparatuses are disclosed.

9. A method of treating a tissue site of a patient, the method comprising:
-
locating granulation tissue at the tissue site; deploying a patterned neo-epithelium dressing comprising; an interface member having a first side and a second, patient-facing side for placing proximate the granulation tissue; and a plurality of three-dimensional features formed on the second, patient-facing side of the interface member, wherein the plurality of three-dimensional features comprise ridges and are patterned after at least one of an epithelial and endothelial lining; applying a contact pressure on the patterned neo-epithelium dressing; allowing formation of neo-epithelium tissue under the influence of the patterned neo-epithelium dressing; and removing the neo-epithelium dressing from the tissue. - View Dependent Claims (10, 11, 12, 13, 14)

15. A system for treating a skin tissue site having granulation tissue on a patient, the system comprising:
-
a patterned neo-epithelium dressing for disposing proximate to granulation tissue on the tissue site, wherein the patterned neo-epithelium dressing comprises; an interface member comprising a medical-grade polyurethane film bonded to a foam having a first side and a second, patient-facing side for placing proximate the granulation tissue; a fluid passageway that fluidly couples the first and second sides of the interface member for delivery of pressure to the second side; and a plurality of three-dimensional features patterned after at least one of an epithelial and endothelial lining having an intact analogous skin pattern and formed on the second, patient-facing side of the interface member; a sealing member for placing over the patterned neo-epithelium dressing and the patient'"'"'s epidermis; a reduced-pressure interface fluidly coupled to the sealing member; and a reduced-pressure source fluidly coupled to the reduced-pressure interface; wherein the interface member is not adherent to the skin tissue site so as to be removable from the skin tissue site after the treating. - View Dependent Claims (16, 17, 18, 19, 20)
