Irene Kochevar and Robert Redmond at the Wellman Center for Photomedicine at Massachusetts General Hospital have developed an innovative new suture method that snubs traditional stitches in favor of a laser. Dubbed laser-bonded healing, the technology uses surgical lasers and a light-activated dye to essentially coax tissue into repairing itself, according to Technology Review. Prior laser stitches were either too hot or too cold to preserve the delicate balance needed to heal a wound, but laser-bonded healing seems to work just right.  "It's a very interesting technology, which would be useful to anyone who does any kind of skin surgery--plastic surgeons, dermatologists," says Robert Stern, a professor of dermatology at Harvard Medical School and chief of dermatology at Beth Israel Deaconess Medical Center in Boston. He notes that the technology must still prove itself, and he isn't yet convinced that the benefits will offset the costs of photochemical dyes and laser equipment, which are far pricier than a needle and thread.
