"I have seen (Veti-Gel) close any size wound that it is applied to," said Landolina. "As long as you can cover it, it can close it,” he added.
The substance, a plant-based synthetic form of a compound in blood that triggers clotting, imitates the body's own healing chemistry to rapidly close punctures to soft tissue.
DARPA has a Foam to Stop Internal Bleeding
Two liquids that turn into a solid foam after being injected into the body may one day save the lives of injured soldiers and wounded civilians by slowing internal bleeding so that they can make it to a hospital. The Defense Advanced Research Projects Agency awarded Arsenal Medical a $15.5 million grant in December to further develop the foam technology, which would be delivered to a wounded soldier through the belly button.
Currently, battlefield medics and paramedics have no tools to stop internal bleeding before an injured person reaches a hospital. “The only thing you can do for that is get to the hospital as soon as possible,” says David King, a trauma surgeon at Massachusetts General Hospital and a co-investigator on the foam project. King, who has served as a military doctor in both Iraq and Afghanistan, says death in these military contexts from uncontrolled internal bleeding is a “regular and routine occurrence.”
“Upwards of a quarter of the people who end up dying in combat could potentially have survived,” says Robert Gerhardt, a physician-scientist at the U.S. Army Institute of Surgical Research at Fort Sam Houston, Texas, who is not involved with the foam project. “We can tie a tourniquet around an arm or leg, but when we get to parts of the body that are not accessible—the abdomen, chest, and to some extent within the head—these are areas of the body we can’t get to directly unless we have a surgeon to open them up, find the bleeding vessel, and clamp it,” he says.
Apply pressure: As shown in this schematic, the Arsenal foam technology is injected through the belly button (top). Once mixed, the two liquids create a foam which eventually expands throughout the abdominal cavity (bottom left). The foam molds to inner structures of the abdomen (bottom right).
