Healing with Laser Heat Surgical lasers could soon heal cuts as well as make incisions.
Colleagues,
As reported in MIT Tech Review ... The promise of medical lasers goes beyond clean incisions and eye surgery: Many believe that lasers should be used not just to create wounds but to mend them too. Abraham Katzir, a physicist at Tel Aviv University, has a system that may just do the trick and is proving successful in its first human trials.
In principle, "laser-bonded" healing offers certain advantages over classic needle-and-thread sutures, including faster healing, decreased risk of infection, and less scarring. Researchers have been working toward flesh-welding lasers for more than a decade, and a number of human trials have shown promise. But what was lacking, until now, was consistency. Flesh, blood vessels, and nerves are delicate tissues that can easily be -- for lack of a better word -- overcooked.
To overcome this problem, Katzir and his colleagues developed a laser-based system with a feedback loop that prevents overheating..."It's a fabulous process, with undeniable biological advantages," says Michael Treat, a surgeon at New York Presbyterian Hospital and associate professor at Columbia University Medical Center...One of Katzir's competitors, Irene Kochevar, is a dermatology professor at Massachusetts General Hospital and is working on her own version of laser-bonded welding, but one that takes advantage of light rather than heat....
