  • Patent number: 5000752
    Abstract: Port 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.

  • Patent number: 4671283
    Abstract: A pair of forceps has a shank and a pair of resilient arms. A groove, running along the inner face of each arm and communicating with a channel in the shank, accommodates a fiber optic cable which provides illumination at the tip of the forceps for items handled by the forceps. The use of the forceps is particularly suitable for manipulating an artificial lens in a human eye because the surface of the lens is illuminated to make it stand out against the liquid of the eye which has substantially the same refractive index as the lens.
