Today on In Case You Missed It: A soft robotic device made by Harvard and Boston Children's Hospital researchers has been tested on pigs and so far, seems quite promising in treating heart disease. The robotic heart wraps around parts of existing tissue and helps squeeze, keeping the blood moving. But unlike other existing devices that are inserted into the heart, this just goes over the top. Its makers believe that will lead to better outcomes for patients that use it, since cycling blood through a medical device can lead to all kinds of complications, from infection to blood clots. No word yet on when they'll begin tests in humans.
