Abstract
In at least one embodiment, a stent comprises an expandable framework comprising a plurality of serpentine bands and a plurality of connector struts. Each serpentine band comprises a plurality of alternating struts and turns. A plurality of the serpentine bands each have their proximal turns aligned on a common stent circumference and comprise first distal turns and second distal turns. The first distal turns are aligned with one another on a common stent circumference. The second distal turns aligned with one another on another common stent circumference. Each band in the plurality comprises first struts and second struts. Each first strut is attached between a proximal turn and a first distal turn, and each second strut is attached between a proximal turn and a second distal turn. The second struts are wider than said first struts.
