    摘要: A balloon catheter comprises a balloon, an inner shaft, an outer shaft and a transition shaft. The transition shaft has a proximal portion and a distal portion joined by a tapered portion. The proximal portion has a diameter greater than the distal portion. The proximal portion has a first end portion engaged to at least a portion of the outer shaft at a first engagement site. At least a portion of the proximal waist is engaged to the proximal portion of the transition shaft at a second engagement site. At least a portion of the end region of the inner shaft is engaged to the distal portion of the transition shaft at a third engagement site. The distal portion extends through the balloon wherein at least a portion of the distal waist of the balloon is engaged to the distal portion of the transition shaft at a forth engagement site.
