Assist. Prof. Dr. Wikunda Limpiangkanan MD., certified Thai board of Dermatology who was granted research scholarship in field of laser surgery at Wellman Center for Photomedicine, Massachusette General Hospital, Harvard Medical School in 2011-2013. She was under supervision of Prof. Richard Rox Anderson, who is a pioneer in laser surgery and a world renowned dermatologist. Her group’s project was to develop a new technique to change the shape and predictably move soft tissue in a particular direction using lasers.
By modified fractional ablative treatment and followed by closure of microscopic holes, the results of in- vivo swine and ex-vivo human skin experiments supported the hypothesis that reducing skin area and moving skin in a preferred direction without causing scar was feasible. This application could be useful in treating some skin conditions such as relieving tension on burn scars, closing a wound or treating skin laxity in the near future.
Dr.Limpiangkanan has filed for patents by the United States Patent and Trademark Office (USPTO) to protect the following inventions.
1.METHOD AND APPARATUS FOR DERMATOLOGICAL TREATMENT
Publication number: 20220054343
Abstract: Exemplary methods and systems can be provided for resurfacing of skin that include formation of a plurality of small holes, e.g., having widths greater that about 0.2mm and less than about 0.7mm or 0.5mm, using a mechanical apparatus. Compressive and/or tensile forces can then be applied to the treated region of skin as the damage heals to facilitate hole closure, and provide enhanced and/or directional shrinkage of the treated skin area.
Type: Application
Filed: April 9, 2021
Publication date: February 24, 2022
Inventors: Richard R. Anderson, Mathew Avram, Fernanda H. Sakamoto, Wikunda Limpiangkanan, William A. Farinelli
2.METHOD AND APPARATUS FOR DERMATOLOGICAL TREATMENT
Patent number: 10888375
Abstract: Exemplary methods and systems can be provided for resurfacing of skin that include formation of a plurality of small holes, e.g., having widths greater that about 0.2mm and less than about 0.7mm or 0.5mm, using a mechanical apparatus. Compressive and/or tensile forces can then be applied to the treated region of skin as the damage heals to facilitate hole closure, and provide enhanced and/or directional shrinkage of the treated skin area.

Abstract: Exemplary methods and systems can be provided for resurfacing of skin that include formation of a plurality of small holes, e.g., having widths greater that about 0.2mm and less than about 0.7mm or 0.5mm, using a mechanical apparatus. Compressive and/or tensile forces can then be applied to the treated region of skin as the damage heals to facilitate hole closure, and provide enhanced and/or directional shrinkage of the treated skin area.

6.METHOD AND APPARATUS FOR DERMATOLOGICAL TREATMENT
Publication number: 20150150629
Abstract: Exemplary methods and systems can be provided for resurfacing of skin that include formation of a plurality of small holes, e.g.,
having widths greater than about 0.2 mm and less than about 0.7 mm or 0.5 mm, using ablative electromagnetic radiation, e.g., optical energy.
An optically transparent plate or window can be pressed over a surface of the skin tissue as the holes are ablated to disrupt formation of a
thermal cuff around the holes. Compressive or tensile forces can then be applied to the treated region of the skin tissue as the damage heals
to facilitate hole closure and provide enhanced and/or directional shrinkage of the treated skin area.
