Longitudinally flexible expandable stent
First Claim
1. A stent comprising a plurality of serpentine bands and a plurality of connector columns, each serpentine band comprising a plurality of alternating straight band struts and turns, adjacent serpentine bands connected across a connector column by a plurality of connector struts, each connector strut connected at one end to a turn of one serpentine band and connected at the other end to a turn of another serpentine band, the turns of a serpentine band comprising connected turns that connect to a connector strut and unconnected turns that do not connect to a connector strut;
- at least one serpentine band comprising a repeating pattern of three band struts, then a connected turn, then five band struts and then a next connected turn as the serpentine band is traversed;
at least one serpentine band comprising a repeating pattern of three band struts, then a connected turn, then one band strut and then a next connected turn, as the serpentine band is traversed; and
at least one serpentine band comprises a repeating pattern of four band struts, then a connected turn, then three band struts, then a next connected turn, then one band strut and then a next connected turn as the serpentine band is traversed.

Abstract
In at least one embodiment, a stent comprises a plurality of serpentine bands and a plurality of connector columns. Each serpentine band comprises a plurality of alternating straight band struts and turns. Adjacent serpentine bands are connected across a connector column by a plurality of connector struts. Each connector strut is connected at one end to a turn of one serpentine band and connected at the other end to a turn of another serpentine band. The turns of a serpentine band comprise connected turns that connect to a connector strut and unconnected turns that do not connect to a connector strut. At least one serpentine band comprises a repeating pattern of three band struts and then five band struts extending between connected turns as the serpentine band is traversed. At least one serpentine band comprises a repeating pattern of three band struts and then one band strut extending between connected turns as the serpentine band is traversed.
