Abstract
A stent may comprise a plurality of serpentine bands connected by connector struts. The stent may further comprise a side branch cell having a plurality of outwardly deployable petals. Each serpentine band may have an approximate longitudinal axis. A portion of the serpentine bands may be flared in the unexpanded state, wherein a portion of the axis of each flared band is oriented helically about a portion of the stent. The bands may reorient during stent expansion, whereafter the axis of each band is oriented in a circumferential direction.
