XSTAT® is a first in kind hemostatic device for the treatment of severe bleeding in the axilla or groin area (known as junctional wounds). XSTAT® works by injecting a group of small, rapidly expanding sponges into a wound cavity using a syringelike applicator. In a wound, the sponges expand and swell to fill the wound cavity within 20 seconds of contact with blood. This process creates a temporary barrier to blood flow and provides hemostatic pressure. Each sponge contains an xray detectable marker to aid in surgical removal.
