There are numerous causes for the formation of scars. Scars are caused by either trauma or a surgical procedure which results in the formation of scar tissue. Scars are often irregularly formed and are often further demarcated by a pigmentary difference from the adjacent normal skin. Scar revision is currently conducted utilizing cryotherapy, pressure therapy, surgery or lasers. A variety of different lasers are used to smooth, flatten or remove the abnormal color of the scar; and there were over 170,000 scar revision procedures performed in the U.S. in 2014 (Lim et al, PRS 2014 Feb 133(2): 398-405).
Excessive scarring can also occur from the excision of a scar lesion. Many of these scars are unsightly due to irregular pigmentation from a shaved lesion excision. Fractional scar revision should reduce the visual impact of these scars by reducing the surface area of these unsightly deformities. The potential also exists to shorten incisions required to elliptically excise lesions of the skin. With this application, each end of the excision will be fractionally resected instead of being lengthened by elliptical excision to avoid a “dog ear” skin redundancy.
The Company expects that the single scalpet and multi-scalpet array platforms will provide medical aesthetic physicians with an effective and less invasive alternative that can be performed in the office setting.
