International ClassA61N 005/06Foreign Application Priority Data1985-12-13 GBAbstractPort wine stain treatment apparatus includes a pad supporting a plurality of diamond tipped needles. The tip of each needle is supplied with laser radiation and the tip acts to scatter laser radiation sideways. Thus, when the pad is applied to the skin, the tips penetrate the skin and when laser radiation is supplied the tips create a laminar radiation profile located below and spaced from the skin surface. In this manner, the cause of the port wine stain can be treated without the danger of disfiguring or scarring the skin surface above the stain.Other References
