Along the way, this company, which is deeply involved in high-end medical devices, has blazed its own path based on the development of innovative medical devices.
Create a “Lanzhou Heart” and set up a leading beacon
In 2019, the 65-year-old Guan Shengmao took the train to Lanzhou in Panjin, Liaoning, just to fulfill his long-cherished wish and thank the “Lanzhou Heart”. In 1986, 32-year-old Guan Shengmao had a heart attack and needed heart valve replacement surgery. However, the General Hospital of the Shenyang Military Region he visited at that time did not have the artificial heart valve needed for the operation, so he had to be transferred to Shanghai Changhai Hospital (the first hospital in China to carry out replacement at that time) heart valve surgery) to perform the surgery. After the operation, a heart valve produced in Lanzhou – “Lanzhou Heart” was implanted in his body, starting his new life.
In 2012, Lanzhou Ximai International Medical Co., Ltd. and Lanzhou Lanfei Medical Devices Co., Ltd. were reorganized, and the latter became a wholly-owned subsidiary of Lanzhou Ximai International Medical Co., Ltd. The heart valve that was reborn to Guan Shengmao was Lanzhou Ximai International. A product of Medical LLC. Today, as another leading product of the company, CL double-leaf artificial mechanical heart valve products have also formed a good brand reputation of “Lanzhou Valve” in China, making Lanzhou Ximai International Medical Co., Ltd. the only two mechanical artificial heart valves in China. One of the manufacturers of heart valves, it has become the leading beacon of artificial mechanical valves in China.
It is understood that currently there are only 6 companies in 3 countries that can produce artificial mechanical heart valves in the world. In addition to 3 companies in the United States and 1 company in Italy, there are 2 companies in China: Beijing Star and Lanzhou Ximai International Medical Co., Ltd. Lanzhou Lanfei Medical, a subsidiary of the company. The valves used clinically in various countries are mainly American valves, accounting for 85% of the market. Under such circumstances, Lanzhou Ximai International Medical Co., Ltd. has established a reputation among patients with its excellent products and has become the “leader” of artificial mechanical valves in China.
Successfully overcame the technical barriers of artificial heart valves, so that Lanzhou Ximai International Medical Co., Ltd. was recognized by the Ministry of Industry and Information Technology as a specialized, special and new “little giant” enterprise in 2019.
