Then you apply a gel to your wound, and the blood stops coming out within seconds. You're healed in minutes. This is the VetiGel, created by Joe Landolina — a 22 year-old who invented the product many years ago. Landolina is now the founder and CEO of Suneris, a company that produces the gel. Suneris announced last week that it would begin to ship VetiGel to vets later this summer. Humans won't be far behind. When injected into a wound site, the gel can form a clot within 12 seconds heal the wound within minutes. Once it hits the damaged tissue, whether it's open skin or a soft organ — livers, kidneys— the gel instantly forms a structure. "What that means, on the one hand, is that the gel will make a structure that holds the wound together," Landolina says.  As fast-acting as VetiGel is, its inventor may be faster. Landolina invented an early version of the gel out of his grandfather's lab. He was still in high school. Over the next four and a half years, Landolina turned the prototype into a business. The first product costs $150. Landolina says Suneris has its sights set on US first, followed by a release in Europe in Asia sometime early next year.
