[0002] Catheter refers to a tubular structure used to transport liquids, gases, etc. in the human body. There are many different catheters in the human body. For example, in the circulatory system, blood vessels are catheters that transport blood; in the respiratory system, the trachea and bronchi are catheters that transport gases; in the digestive system, the esophagus, bile duct, etc. have a transporting function. In the urinary system, the ureters, urethra, etc. are also catheters that transport liquids. These catheters play an important role in their respective systems, helping the human body to exchange substances and regulate functions between organs. When problems occur in these catheters, the functions of the corresponding systems may be affected. In some medical treatments, it may be necessary to operate the catheters, such as angiography, stent implantation, and thrombus removal, to restore their normal functions.
