A bioengineering professor at UC San Diego created a company called Karios. It designed a protective shield for when it takes a second operation to fix what’s wrong with the heart.
This undated illustration of a human heart shows how surgery removes a protective barrier from the organ, causing it to adhere to other tissues. The second image shows how a gel can be sprayed on the exposed heart to protect it as it heals.
Grover said when heart surgery first takes place, that exposure removes the heart’s protective barrier. And, in that state, it will very easily stick to other tissues in the chest cavity. “At the end of that first surgery, the surgeon would spray the material over the heart to create that protective layer,” said Christman. “So, a very thin protective layer that coats the heart, maybe one millimeter. It will degrade over time, but it will get the heart through that window of the first several weeks.”
