US 2007/0191927 A1 · Stent with orientation-dependent properties

Abstract

A method and device for implantation into a curved vessel is described. The device may be a stent with a generally curved configuration in its radially expanded state. The stent may have a first series of linkages located along a first side of the stent and a second series of linkages located along a second side of the stent. Both series of linkages interconnect structural elements of the stent. During deployment of the stent into a vessel, the second series of linkages undergo longitudinal expansion sufficient to produce a stent having a longer second side than a first side. This difference in longitudinal length between the second side and first side of the stent creates a curved configuration which conforms to the curvature of the vessel which it is implanted into.

Dependent claims

An intraluminal device, comprising:

a tubular structure comprising a plurality of structural elements, said tubular structure having a first end and a second end, a circumference of said tubular structure including a first side and a second side, said first side of said circumference comprising a first pattern of said structural elements and said second side of said circumference comprising a second pattern of said structural elements, said first pattern expandable to a first length between said first end and said second end and said second pattern expandable to a second length between said first end and said second end, said first pattern being different than said second pattern and said first length being shorter than said second length, and wherein said tubular structure in an expanded condition comprises a curved shape.
