A Super-Elastic Surgical Glue That Sticks And Seals In Vivo, Even When Tissues Are Moving, Science Translational Medicine Reveals

To repair ruptured or pierced organs and tissues, surgeons commonly use staples, sutures and wires to bring and hold the wound edges together so that they can heal. However, these procedures can be difficult to perform in hard-to-reach areas of the body and wounds are often not completely sealed immediately. They also come with the risk that tissues are further damaged and infected. A particular challenge is posed by wounds in fragile or elastic tissues that continuously expand or contract and relax, like the breathing lung, the beating heart and pulsing arteries.
