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.
Claims13
A system for skin tightening comprising:
- a tube configured to contact a surface of skin to generate holes in skin tissue by excising portions of the skin tissue;
- a first actuator configured to rotate the tube relative to the skin;
- a suction or pressure system to facilitate removal of skin portions from the tube;
- a stop arrangement to control the depth of the excision and/or the length of excised tissue portions, wherein the stop arrangement is adjustable along a long axis of the tube 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.
