1. A stent comprising:
A proximal end and a distal end, a plurality of serpentine bands including a first substantially serpentine band and a second substantially serpentine band, the serpentine bands formed of interconnected expansion struts, each two interconnected circumferentially adjacent expansion struts forming an expansion strut pair having a closed end and an open end, the expansion struts of the first substantially serpentine band and the expansion struts of the second substantially serpentine band forming stepped notches along their lengths, the first substantially serpentine band and the second substantially serpentine band connected by at least one connection member, the connection member having a first end and a second end, the connection member extending from and connecting one expansion strut of an expansion strut pair of the first serpentine band to one expansion strut of an expansion strut pair of the second serpentine band, wherein
the first end of the connection member forms a linear extension of the one expansion strut in the first serpentine band and extends adjacent to a closed end in the same direction as the one expansion strut in the first serpentine band, the first end extending further toward the proximal end of the stent than the closed end adjacent thereto, andthe second end of the connection member forms a linear extension of the one expansion strut in the second serpentine band and extends adjacent to a closed end in the same direction as one expansion strut in the second serpentine band, the second end extending further toward the distal end of the stent than the closed end adjacent thereto. |
