DARPA-funded research could block internal bleeding with expanding foam

DARPA has awarded more funding to researchers who are testing a type of expandable foam that could stop internal bleeding long enough to get soldiers off a battlefield. The foam, developed by Arsenal Medical and presented earlier this year before the American Association for the Surgery of Trauma (AAST), is meant to stop internal hemorrhages that can’t be compressed with traditional approaches. It’s injected into the chest as a pair of separate chemicals, which expand when they come into contact with each other. The result is a thick foam that spreads and solidifies around the chest cavity, stopping bleeding until the patient can be taken to surgery. At that point, it can be removed in a single block.
