1. A method of skin tightening comprising:
- (i) producing a plurality of excised tissue portions in a region of skin tissue using a system comprising,a plurality of tubes configured to contact a surface of the skin to generate holes in the skin tissue by excising portions of the skin tissue;
a first actuator configured to rotate and/or translate the plurality of tubes relative to the skin; and
a suction or pressure system to facilitate removal of tissue portions from the plurality of tubes; and
(ii) affixing to the skin region a device that provides contraction or expansion of said skin region in one or more directions;
wherein at least one of said excised tissue portions has at least one dimension that is less than 2 mm.

Abstract
The present invention relates to methods and devices for skin tightening after incising or excising tissue portions from a subject. Exemplary methods and devices include tunable dressings having an adhesive layer and a regulatable layer or an un-stretched layer that responds to one or more external stimuli to contract or expand the dressing, where the contraction or expansion can be uniform or non-uniform.

21. A system for skin tightening comprising:
-
a plurality of tubes configured to contact a surface of the skin to generate holes in skin tissue by excising portions of the skin tissue; a first actuator configured to rotate the plurality of tubes relative to the skin; a suction or pressure system to facilitate removal of skin portions from the tubes; a stop arrangement to control the depth of the excision and/or the length of the excised tissue portions, wherein the stop arrangement is adjustable along a long axis of at least one of the plurality of tubes to control the depth of excision in the skin; and a device affixable to a skin region comprising a plurality of the excised tissue portions, wherein said device provides contraction or expansion of said skin region in one or more directions. - View Dependent Claims (22, 23, 24, 25)

26. A method of skin tightening comprising:
-
(i) producing a plurality of excised tissue portions in a region of skin tissue using a system comprising, a plurality of hollow tubes configured to contact a surface of the skin to generate holes in the skin tissue by excising portions of the skin tissue, which hollow tubes have an inner diameter that is less than 0.5 mm; a first actuator configured to rotate and/or translate the plurality of tubes relative to the skin; and a suction or pressure system to facilitate removal of tissue portions from the plurality of hollow tubes; and (ii) affixing to the skin region a device that provides contraction or expansion of said skin region in one or more directions.

27. A method of skin tightening comprising:
-
(i) rotating and/or translating a plurality of tubes relative to a skin tissue, and contacting the tubes with a surface of the skin tissue, thereby excising from a region of the skin tissue one or more tissue portions having at least one dimension that is less than 2 mm into the tubes; and applying a suction or pressure force to facilitate removal of the excised tissue portions from the tubes; and (ii) affixing a device to the region, wherein said device provides contraction or expansion of said region in one or more directions.
