Medical catheters come in a variety of sizes for various applications. From Foley catheter, a flexible tube that a clinician passes through the urethra and into the bladder to drain urine, to coronary stent, a tube-shaped device placed in the coronary arteries that supply blood to the heart, to keep the arteries open in the treatment of coronary heart disease, they address medical conditions in different fields, from urology, to cardiology, gastroenterology, gynaecology, and more.
