In many countries, surgery is hindered by access to blood and a lack of blood banks. New technology is enabling doctors to re-use blood, which is even more effective than donor blood, but this technology is expensive and out of reach of developing nations. In turn, Carolyn Yarina developed Hemafuse, a surgical tool to recycle a person’s own blood from internal bleeding.
