Abstract
A balloon catheter and its pilot balloon system visually indicate the state of the inflation of a balloon placed in a human body. The small pilot balloon is conveniently manufactured by blow molding utilizing substantially the same material and has substantially the same structure as the main balloon. The pilot balloon is useful for a catheter with balloon or a tube with cuff where the balloon or the cuff is made of a very resilient material. The preferred material is a blend of composition having certain properties comprising styrenic thermoplastic elastomer and polyolefin.
