DELIVERY DEVICE AND METHOD OF DELIVERY

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.

主权项

1. An intraluminal device deployment method comprising:
advancing a delivery device with a plurality of intraluminal devices in a compressed state to a treatment area,
each of the plurality of intraluminal devices comprising a plurality of struts and a radiopaque marker positioned in a central region of the intraluminal device, each of the plurality of intraluminal devices being a same size with the radiopaque marker positioned in a same location,the delivery device comprising an inner shaft having a plurality of delivery platforms, each intraluminal device of the plurality of intraluminal devices positioned at a respective delivery platform of the plurality of delivery platforms, and an outer sheath covering the inner shaft and the plurality of delivery platforms, the outer sheath having a radiopaque marker band positioned proximally from a distal end of the outer sheath; withdrawing the outer sheath until the radiopaque marker band on the outer sheath and radiopaque marker on a first intraluminal device to be delivered of the plurality of intraluminal devices are aligned; aligning the aligned radiopaque marker band and the radiopaque marker with the treatment area before release of the first intraluminal device; withdrawing the outer sheath to release the first intraluminal device; and withdrawing the outer sheath until the radiopaque marker band on the outer sheath and radiopaque marker on a second intraluminal device to be delivered of the plurality of intraluminal devices are aligned.
