My son was born with a very minor heart defect where there’s a small hole between two chambers of the heart. Instead of open-heart surgery, they did a procedure where they accessed his heart with a catheter via an artery in his leg. The plug they placed is made of nitinol, which meant it could be compressed very tightly for insertion and then returned to its original shape when exposed to body heat. Scar tissue grows around the plug and holds it in place. I thought the tech was super cool, and we of course were very thankful that he could be in and out of the hospital in a day. Was even up and eating cake for lunch within an hour of leaving the operating room.
