Injectable tissue bandage to mend damaged heartsScientists 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 or tissues 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.

If an implant requires open-heart surgery, it’s not going to be widely available to patients.
