The Abbott valve repair device, which essentially clips the mitral valveshut, was tested in a study that company-funded researchers said showed it was roughly equivalent to surgery.
That starts off with a "junk shot, " in which material such as rubber tires and golf balls is pumped into the shut-off valve, or blowout preventer, that sits atop the well.
Among other response activities are on-water skimming, subsurface wellhead operations, continued efforts to see if they can get that shut-off valve to close, and significant booming efforts underway to protect vital shoreline.
