Longitudinally flexible expandable stent
First Claim
Patent Images
1. A cylindrical expandable stent comprising:
- a plurality of undulating band-like elements, the band-like elements having alternating peaks and troughs, aligned on a common longitudinal axis to define a generally tubular stent body, the peaks and troughs taking a generally longitudinal direction along the cylinder, and a plurality of interconnecting elements each interconnecting element having a first end and a second end, the first and second ends extending from adjacent band-like elements, the first and second ends displaced circumferentially along the stent.

Abstract
Segmented articulatable stent of open structure comprised of end-connected struts of first and second lengths making up first and second segments with angular interconnects between adjacent first and second segments.

25. A tubular, flexible, expandable stent having a longitudinal axis, comprising:
-
one or more cylindrical shaped first segments, each first segment having first struts having first and second ends, the first segment being defined by a member formed in an undulating pattern of interconnected paired first struts and in which adjacent pairs of first struts in a given first segment are interconnected at opposite ends, one or more cylindrical shaped second segments, each second segment being defined by a member formed in an undulating pattern of interconnected paired second struts and in which adjacent pairs of second struts in a given second segment are interconnected at opposite ends, the first struts being shorter than the second struts, the first segments formed of a number of first struts and the second segments formed of a number of second struts, the number of first struts in a first segment exceeding the number of second struts in a second segment. the first and second segments aligned on a common longitudinal axis to define a generally tubular stent body, the first and second segments present along the stent body, and adjacent first and second segments connected by a plurality of interconnecting elements, each interconnecting element having a first end and a second end, each interconnecting element extending from an end of paired first struts on a first segment to an end of paired second struts on an adjacent second segment, each first end of an interconnecting element displaced circumferentially along the stent from each second end of an interconnecting element. - View Dependent Claims (26, 27, 28)
