The angiographic catheter is used in coronary angiography to inject contrast agents or other drugs, thereby evaluating the course, number, and malformations of the coronary arteries; assessing the presence, severity, and extent of coronary artery disease; and evaluating functional changes in the coronary arteries, including coronary spasm and the presence or absence of collateral circulation. It can also evaluate left ventricular function simultaneously. Based on this, interventional treatment can be performed according to the degree and range of coronary artery disease; the effectiveness of coronary artery bypass surgery and interventional treatment can be evaluated; and long-term follow-up and prognosis evaluation can be conducted.


Kestat, after nearly 20 years of development, has its products covering more than 20 countries globally. Among these, the angiographic catheter, developed in 2015, quickly opened up both domestic and international markets within just four years. OEM domestic sales have reached provinces such as Guangdong and Beijing, while internationally, it is exported to countries like Russia, Turkey, and Japan. Its high-quality standards have received high praise from clients; Japanese customers have reported that the quality of the product can rival Terumo, Japan’s largest brand of angiographic catheters. Currently, annual sales reach over 60,000 units. Considering strategic factors, the company registered its own brand of coronary angiographic catheters. Leveraging years of experience in the research and production of precision medical catheters, as well as OEM experience with coronary angiographic catheters, the company developed its own product – PILOSOL Xianghe. This marks the company’s official entry into the domestic cardiac interventional product field, laying a solid foundation for further development of cardiac interventional products and providing cost-effective cardiac interventional medical solutions to domestic medical institutions.
