Abstract: A stent delivery device for delivering a self-expanding stent comprises an inner sheath including a proximal end portion and a distal end portion, a stent stopper including a stopper main body that is circumferentially disposed over at least a portion of the inner sheath at the proximal end portion, and at least one projection extending radially outward from the stopper main body for releasably engaging a portion of the self-expanding stent, and an outer sheath slidably disposed over the inner sheath and the stent stopper. The at least one projection includes a distal end surface and a proximal end surface, and the proximal end surface includes a recess extending into a body of the projection toward the distal end surface.
