Abstract
An stent delivery device comprises a tubular shaft body, a foldable and inflatable balloon attached to the distal end portion of the shaft body, and a stent fitted over the folded balloon. The shaft body has a lumen for inflating the balloon which communicates with the inside of the balloon. The balloon has an inflatable portion which is inflated into the shape of an approximately uniform-diameter cylinder by a fluid injected through the lumen. The stent delivery device further has a distal side stopper which is secured close to the distal end of the inflatable portion of the balloon and prevents the shift of the stent toward the distal side, and a proximal side stopper which is secured close to the proximal end of the inflatable portion of the balloon and prevents the shift of the stent toward the proximal side.
