A new glue made of human blood by-products could replace stitches and surgical staples in some delicate operations and be used like a caulking agent on leaky blood vessels, University of Pennsylvania researchers say.
Dr. Robert Weisman said he and colleagues have worked on developing such a glue for seven years. The substance is made from clotting agents derived from the patient's own blood.
"There are operations where it's just too difficult to use sutures or wires," he said. "You need an adhesive that is not traumatic. Glue is a natural answer."
Weisman said the glue, which is thick and white, is used just like household glue. It is applied to tissue and bone with a fine needle, he said. "Healthy tissue grows around it and the glue itself eventually dissolves. We believe, although we have no proof, the glue actually helps the healing process."
