Abstract
A balloon catheter includes an inner tube and a balloon fixed to the inner tube. The balloon includes at least one first valley portion having a first distance to the inner tube, and at least one second valley portion having a second distance to the inner tube that is longer than the first distance. The first valley portion having the shorter distance to the inner tube can be preferentially depressurized for quick folding when the balloon transitions from an expanded state to a folded state. The second valley portion having the longer distance to the inner tube can be preferentially pressurized for quick expansion when the balloon transitions from a folded state to an expanded state.
