New surgical glue could provide alternative for heart procedures

People who need multiple surgeries for congenital heart defects undergo procedures that are invasive and challenging partly due to an inability to quickly and safely secure devices inside the heart. Sutures take too much time to stitch and can stress fragile heart tissue, and available clinical adhesives are sub-par.
 The creation of a safe and effective adhesive that can be used internally in the body would help these patients, but researchers trying to develop a glue like this have faced hurdles such as ensuring that it is non-toxic and capable of repelling fluids. Now, a study published by Harvard Medical School offers a potential breakthrough.
