ABSTRACT:
A catheter balloon is configured to improve its fold-in or collapsing behavior. The catheter balloon has a balloon body portion, a first tapered end portion and a second tapered end portion. The balloon body portion has a substantially cylindrical shape in an expanded state. The first tapered end portion is formed at a first end of the balloon body portion. The first tapered end portion includes a first predetermined embossment. The second tapered end portion is formed at a second end of the balloon body portion. The second tapered end portion includes a second predetermined embossment. The balloon body portion is formed free of a predetermined embossment. In other words, the balloon body portion is formed without folds so that there is only predetermined folding on the conical end portions for inducing the folding of the balloon body portion in a predetermined direction upon collapsing.
