It seems that "Veti" just refers to the veterinary application. I've played with similar would healing biomaterials before, and from the (scarce) available materials, it looks like they're using a sodium-alginate based polymer, which can be chemically crosslinked with calcium ions. With some additional clotting factors and tissue sealing agents (tranglutaminase comes to mind), rapid wound closure looks pretty feasible.
