Scientists have developed an injectable tissue bandage smaller than a postage stamp that can repair damaged hearts. Repairing heart tissue destroyed by a heart attack or medical condition with regenerative cells usually requires invasive open-heart surgery.
Researchers at the University of Toronto in Canada have developed a technique that lets them use a small needle to inject a repair patch, without the need to open up the chest cavity. The AngioChip is a tiny patch of heart tissue with its own blood vessels and heart cells beating with a regular rhythm. Miles Montgomery, a PhD candidate, spent nearly three years developing a patch that could be injected, rather than implanted. Source The Hindu.
