Description

technical field

[0001] The present invention relates to a medical device, especially a kind of artificial aortic valve which can replace the aortic valve and pulmonary valve without surgery, and specifically a percutaneous aortic valve or pulmonary valve replacement device. . Background technique

[0002] Since Starr and Harken succeeded in replacing the mitral valve and aortic valve for patients with artificial valves respectively in 1960, surgical valve replacement is the most effective method for the treatment of severe heart valve diseases, and valve replacement is performed for more than 100,000 patients every year Operation. Artificial valves are divided into two categories: biological valves and mechanical valves. There are more than 100 types, each with its own advantages and disadvantages in clinical use, and the vast majority of artificial valve replacement operations are performed with the support of a systemic pulmonary circulation machine, which makes infants w...
