## Abstract

A delivery device can provide sequential delivery of a plurality of intraluminal devices or tacks held in a compressed state on the delivery device. Delivery platforms on the delivery device can hold a tack in a compressed position and be positioned between annular pusher bands that may also be radiopaque markers. The annular pusher bands can be made of wire or sections of material to increase flexibility while remaining radiopacity. A post deployment dilation device can be included. The post deployment dilation device can be a plurality of expansion filaments, a bellows, or a balloon. A tack deployment method can include allowing a self-expanding tack to expand, aligning the post deployment dilation device under the tack, and causing the post deployment dilation device to expand radial to push outward on the tack.
