Abstract
A scoring device includes an elongate shaft, a balloon disposed on a far side of the shaft and inflatable radially of the shaft by a fluid flowing into the balloon, at least one storage tube disposed along an outer surface of the balloon and having a storage lumen defined therein, and an elongate scoring wire storable in the storage tube and made of a harder material than the balloon. The storage tube is fixed to the balloon or the shaft, and an opening portion is defined in the storage tube to provide fluid communication between outer and inner circumferential surfaces of the storage tube along the storage lumen when the balloon is inflated. The scoring wire is movable in the storage lumen along a longitudinal axis of the storage tube.
