Abstract:
A delivery system comprising an endoluminal device, an outer sheath that radially surrounds the endoluminal device, a pusher positioned at one end of the endoluminal device, and a linkage between the pusher and the outer sheath that coordinates movement of the outer sheath in a first direction with simultaneous movement of the pusher in a second direction opposite the first direction. This delivery system is particularly useful for endoluminal devices that foreshorten, and may comprise the outer sheath moving a first distance (d1) and the pusher moving a second distance (d2), where d2/d1 is approximately equal to the foreshortening ratio. The delivery system of this invention enables a foreshortening device, such as a vena cava filter, or stent, graft, or combination thereof, to be deployed with its end in a precise deployment location without foreshortening causing the end to move from the deployment location as the stent expands.
