I took it out. Cardiovascular balloon is a kind of medical instrument used to treat heart disease, which is often used in coronary intervention. In the process of interventional therapy, the doctor inserts the balloon into the coronary artery through the catheter, and then inflates the balloon to dilate the narrow blood vessels and improve the blood supply to the heart. After the treatment, the balloon will be taken out to avoid unnecessary stimulation and damage to blood vessels. The doctor will take the balloon out through the catheter and then take it out of the body.
