Rapid Hemostasis System Seals Gunshot Wounds

A novel hemostatic device helps control severe, life-threatening bleeding from narrow entrance extremity injuries and junctional wounds in the groin.

The RevMedx (Wilsonville, OR, USA) XStat is a syringe-like applicator intended for the treatment of severe bleeding from bullet or knife wounds located in an arm or leg, and for wounds in junctional areas such as the groin or shoulder that are not amenable to tourniquet application. XStat is filled with compressed sponges coated with a hemostatic agent that expand once in contact with a liquid, rapidly filling a substantially larger volume. Besides helping to block blood flow, the sponges also provide a surface on which blood clots can begin to form. Since the sponges have to be eventually removed, each has a radiopaque marker.

Two applicator sizes are available, a 30 mm diameter applicator for wide wound tracks and a 12 mm diameter applicator for narrower ones. The XStat-30 applicator holds 92 tablet-sized mini-cellulose coated sponges that are capable of absorbing 570 ml blood. It includes with a sealed valve tip designed to prevent fluid ingress and to minimize the risk of premature sponge expansion; a telescoping handle mechanism allows the device to be stored in a shortened state. The slimmer XStat-12 applicator consists of a cylindrical applicator body with a frangible tip and a detachable plunger.

“Our mission is to reduce death and disability from traumatic bleeding injuries caused by war, violence or accidents,” said Andrew Barofsky, CEO of RevMedx. “The expansion of XSTAT’s indications accelerates fulfillment of this mission by providing first responders with an additional capability to treat penetrating injuries located in an arm, leg, shoulder, or groin.”
