Abstract
A catheter with a balloon for mitral valve formative operation includes a double tube having an inner tube and an outer tube disposed concentrically. A balloon is fastened at one end to the inner tube and at the other end to the outer tube. A balloon-extending pipe stopper is disposed at the tip of the inner tube and includes an entry diameter at one end sized to receive a balloon-extending pipe with an allowance. An inner diameter of the balloon-extending pipe stopper at an opposite end is smaller than the entry diameter. The inner diameter of the extending pipe stopper is substantially equivalent to a diameter of the balloon-extending pipe. In use, the balloon-extending pipe is inserted into the inner tube and brought into contact with the balloon-extending pipe stopper for axially extending the balloon for contraction in diameter.
