It is widely known that heart wounds are difficult to repair. Due to constant heart moving it is very complicated to hold wound's edges together in order to provide the contact and ability to repair the muscle. Previously threads and staples were used in such situations. Of course, they are not a best solution, because damage of the muscle occurring during theirs usage.
Now it seems that the era of threads and staples is coming to the end. Scientists from Harvard Medical School created a special glue, which is able to stick together the edges of a wound and after solidification to expand and contract with the heart muscle. Thus surgeons do not need any more threads and staples! Remarkably, that the glue can be applied not only to the heart wounds, but to intestines and blood vessels too.
