Abstract
A stent comprises a plurality of serpentine circumferential bands and a plurality of connector columns. Each connector column is located between two adjacent serpentine circumferential bands and comprises a plurality connector struts. Each connector strut is connected at one end to one serpentine circumferential band and at another end to another serpentine circumferential band. Each connector column may contain multiple types of connector struts having varying circumferential spans. Each serpentine circumferential band may have sections which vary in amplitude and/or wavelength.

38. A stent having a proximal end and a distal end, the stent comprising:
-
a plurality of serpentine circumferential bands, each serpentine circumferential band having a proximal end portion and a distal end portion;
said serpentine circumferential band proximal end portion having a plurality of first proximal turns and a plurality of second proximal turns, wherein said first proximal turns extend farther toward the stent proximal end than said second proximal turns;
said serpentine circumferential band distal end portion having a plurality of first distal turns and a plurality of second distal turns, wherein said first distal turns extend farther toward the stent distal end than said second distal turns; and
a plurality of connector columns, each connector column located between two adjacent serpentine circumferential bands, each connector column comprising a plurality of connector struts including at least one first type of connector strut and at least one second type of connector strut, each connector strut coupled at a first end to a serpentine circumferential band and coupled at a second end to another serpentine circumferential band. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57)

58. A stent having a proximal end, a distal end and a longitudinal axis, the stent comprising:
-
a plurality of serpentine bands including a first end serpentine band, a second end serpentine band and at least one interior serpentine band, each interior serpentine band comprising alternating turns connected by struts, the struts comprising a strut having a first length, a strut having a second length and a strut having a third length; and
a plurality of connector columns, each connector column located between two adjacent serpentine bands, each connector column comprising a plurality of connector struts including at least one first type of connector strut and at least one second type of connector strut, each connector strut coupled at a first end to a serpentine band and coupled at a second end to another serpentine band;
wherein a first type of connector strut is parallel to the longitudinal axis, and the first end of a second type of connector strut is longitudinally and circumferentially offset from the second end.
