The ingenious XStat device from RevMedX, which is designed to stop bleeding from a gunshot or shrapnel wound in under 20 seconds, has just been approved by the FDA. The injector quickly fills a deep wound with a handful of pill-shaped sponges that instantly expand on contact with blood, giving the patient more of that critical time to get to a hospital.
