Abstract
A stent may be constructed comprising a plurality of interconnected circumferential bands each bands comprising a plurality of concave and/or convex M-shaped segments joined together by loops.
Claims16
A stent having a proximal end and a distal end, the stent comprising a plurality of interconnected circumferential bands with a flowpath therethrough,
- at least one of the circumferential bands including:
- a plurality of substantially M-shaped segments and
- a plurality of substantially C-shaped segments, each substantially C-shaped segment being connected to at least one substantially M-shaped segment, the substantially C-shaped segments of each circumferential band having a substantially uniform orientation, the plurality of substantially M-shaped segments and the plurality of substantially C-shaped segments defining a repeating pattern of curved strut members, the pattern comprising a plurality of first groups of curved strut members and a plurality of second groups of curved strut members, wherein the first groups and the second groups are alternatingly arranged, each of the first groups comprising at least three consecutive curved strut members having substantially the same curvature, each of the second groups comprising at least three consecutive curved strut members having substantially the same curvature but substantially opposite the curvature of the at least three curved strut members of each of the first groups, at least one curved strut member of each of the first groups being connected to at least one curved strut member of an adjacent second group.
A stent having a proximal end and a distal end, the stent comprising a plurality of interconnected circumferential bands with a flowpath therethrough,
- at least one of the circumferential bands comprising a repeating pattern of curved strut members, the pattern comprising a plurality of first groups of curved strut members and a plurality of second groups of curved strut members, wherein the first groups and the second groups are alternatingly arranged, each of the first groups comprising at least three adjacent curved strut members having substantially the same curvature, each of the second groups comprising at least three adjacent curved strut members having substantially the same curvature but substantially opposite the curvature of the at least three curved strut members of each of the first groups, only one curved strut member of each of the first groups being connected to only one curved strut member of an adjacent second group.
A stent having a proximal end and a distal end, the stent comprising a plurality of interconnected circumferential bands with a flowpath therethrough,
- at least one of the circumferential bands comprising a repeating pattern of curved strut members, the pattern comprising a plurality of first groups of connected curved strut members and a plurality of second groups of connected curved strut members, wherein the first groups and the second groups are alternatingly arranged, each of the first groups comprising at least three adjacent curved strut members having substantially the same curvature, each of the second groups comprising at least three adjacent curved strut members having substantially the same curvature but substantially opposite the curvature of the at least three curved strut members of each of the first groups, a first curved strut member of each of the first groups is connected to a first curved strut member of an adjacent second group wherein the connected first curved strut member of each first group and the first curved strut member of the adjacent second group form an omega-shaped segment.
