First Claim
1. A stent comprising a plurality of interconnected serpentine bands,each serpentine band having alternating straight struts and s-shaped struts forming peaks and valleys, each straight strut connected at one end to one s-shaped strut and at a second end to a second s-shaped strut, each s-shaped strut connected at one end to one straight strut and at a second end to a second straight strut, one end of the s-shaped struts connected to one end of the straight struts at a peak and another end of the s-shaped struts connected to one end of the straight strut at a valley,adjacent serpentine bands connected by a plurality of linear connectors, each linear connector extending from a peak of one serpentine band to a valley of another serpentine band adjacent thereto,wherein a straight strut comprises a width, and a valley connected to the straight strut comprises a width that is greater than the width of the straight strut.

Abstract
A stent may comprise a plurality of serpentine bands, wherein adjacent serpentine bands are connected by at least one connector strut. A serpentine band may comprise alternating straight struts and s-shaped struts. Connector struts may comprise first connector struts and second connector struts, wherein the first connector struts are nonparallel to the second connector struts.
