Medical tube and balloon catheter

The invention provides a medical tube and a balloon catheter, the balloon catheter comprises an inner tube, the inner tube is the medical tube, the medical tube comprises a first tube body and a second tube body, and the second tube body sleeves the outer surface of the first tube body; wherein the second pipe body is a metal hypotube, and the friction coefficient of the inner surface of the first pipe body is smaller than that of the inner surface of the second pipe body. The medical tube has good pushing performance, when the medical tube is arranged on a guide wire in a sleeving mode and advances along the guide wire, friction force generated between the medical tube and the guide wire is small, the smoothness of the medical tube in the advancing process is improved, and the situation that due to retardation, operation time is prolonged is avoided. 本发明提供了一种医用管材及球囊导管，所述球囊导管包括内管，所述内管为所述医用管材，所述医用管材包括第一管体和第二管体，所述第二管体套装在所述第一管体的外表面上；其中，所述第二管体为金属海波管，所述第一管体之内表面的摩擦系数小于所述第二管体之内表面的摩擦系数。所述医用管材具有良好的推送性，且所述医用管材在套装在导丝上并沿
