摘要:
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 have a unique shape, such as a non-constant outer diameter, an hourglass shape, a tapered proximal half, ridges, dimples, etc. This unique shape can be positioned between annular pusher bands that may also be radiopaque markers. In some embodiments, the unique shape is provided by a sleeve of flexible material with the unique shape surrounding a harder inner shaft. Further, the annular pusher bands can be made of wire or sections of material to increase flexibility while remaining radiopacity. A tack deployment method can include alignment of radiopaque markers on the outer sheath and the tack to be deployed prior to deployment.
