Abstract
A catheter with a balloon characterized by a balloon reinforced with a composite yarn consisting of an elastic yarn and a non-elastic yarn with a larger free length of the non-elastic yarn than that of said elastic yarn. When the catheter is inserted into a blood vessel or taken out on a surgical operation, the balloon is deflated to a small diameter without producing any wrinkle and is stretched by inflation to the same size and the same shape at any time. Therefore, reliability of the balloon catheter in surgical operation is improved and the cut wound in the surgical operation is smaller. Treatment and management after the surgical operation are simple and the time required for recovery is extremely short.
