Built on research by Dr. David Farrell, an OHSU professor and founder of Gamma Therapeutics, the sealant can be sprayed or dripped onto a wound, and once dissolved with water the clotting process to form the seal begins. Farrell says the sealant would be most useful where there is significant tissue damage, such as from trauma surgeries and hip or knee replacements. A patent is pending for the Gamma Seal while grant requests are being made to the National Institutes of Health and the Department of Defense.
