An Oregon company is ramping up to produce an Army-backed sponge that could save lives by slowing bleeding from some battlefield wounds in seconds.
RevMedx received approval in April from the Food and Drug Administration to produce XStat, a compressed sponge looks like an antacid tablet but expands many times its size when exposed to fluids, such as blood. The material is also treated with a hemostatic agent, which quickly coagulates the blood flow.
A large syringe is used to inject dozens of the sponges deep into a wound, and its inventors say blood flow can be staunched as quickly as 20 seconds.
