Abstract:
1. A stent comprising: an expandable framework comprising multiple serpentine bands and a plurality of connector struts, each connector strut attached between two adjacent serpentine bands; each serpentine band comprising a plurality of alternating struts and turns, said turns comprising alternating proximal turns and distal turns, each serpentine band forming a closed tubular structure; a plurality of said serpentine bands each having their proximal turns aligned on a common stent circumference and comprising first distal turns and second distal turns, the first distal turns aligned with one another on a common stent circumference, the second distal turns aligned with one another on a common stent circumference and offset from the first distal turns; a distal end band comprising struts, first proximal turns, second proximal turns and distal turns, the distal turns aligned with one another on a common stent circumference, the first proximal turns aligned with one another on a common stent circumference, the second proximal turns aligned with one another on a common stent circumference and offset from the first proximal turns, at least one strut of the distal end band comprising a tapered portion and a non-tapered portion; each connector strut attached between one of the second distal turns of one serpentine band and one of the proximal turns of an adjacent serpentine band.
