One of the company's ground-breaking hemorrhage control products is the FDA-approved XStat , a device used to treat gunshot and shrapnel wounds on the battlefield. It works by injecting a group of small, rapidly-expanding sponges into a wound cavity using a syringe-like applicator. Once in, sponges expand and swell to fill the wound cavity within 15 seconds of contact with blood, creating a barrier to block blood flow and provide pressure.

"The product puts internal pressure in the wound, which frees up the medic to continue to work on other wounds or even to stabilize another casualty in that three minutes he would have had to hold pressure," he said.
