The application prospects of medical catheters are broad. The annual sales of various catheters worldwide have reached billions of dollars, and the number of medical catheters used for the treatment of coronary heart disease in the United States alone has reached hundreds of thousands, worth billions of dollars. In China, various interventional treatment techniques using catheters have been popularized in most tertiary hospitals, and the demand for medical catheters is increasing. However, the vast majority use imported catheters.
Compared with developed countries abroad, the development of medical catheters in China is relatively backward, especially in the field of high-tech interventional catheters. According to incomplete statistics, the value of imported medical catheters in China now exceeds 150 million US dollars annually. Imported catheters are mainly high-precision interventional therapy catheters. Due to their dependence on imports, the development of interventional medicine in China has been greatly restricted, and the high prices of imported products are also unaffordable for most people.
