“ClotBuster” Device for Stroke

More than a half century ago, Swedish scientists in Uppsala and Stockholm developed the stereotactic radiosurgery technology for what became known as the “Gamma knife.” The idea was to direct multiple beams of cobalt 60 radiation through ports in a collimator helmet so they could all intersect at a brain tumor site. Now, researchers at the University of Arkansas have built a “halo” device that fits around the skull, with ultrasound sixteen transducers located at thin spots in the bone, that can break up blood clots of stroke victims (when used in conjunction with tissue plasminogen activator). Clinical testing is now going on. MORE
