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 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 connecting 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,whereinthe 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 first end extending further toward the distal end of the stent than the closed end adjacent thereto.

Abstract
A stent comprises a first expansion strut column of first expansion strut pairs and a second expansion strut column of second expansion strut pairs. Each first expansion strut pair is connected to a second expansion strut pair by a connecting strut. Each connecting strut comprises at least one wrap portion, the at least one wrap portion being at least partially wrapped about at least one of the first joining portions of at least one of the first expansion strut column and the second expansion strut column.

6. A stent comprising:
-
A proximal end and a distal end, a plurality of serpentine bands, 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, a plurality of connector member extending between the serpentine bands, each connection member having a first end and a second end and extending from and connecting one expansion strut of an expansion strut pair of one serpentine band to one expansion strut of an expansion strut pair of another serpentine band, wherein the first end of each connection member forms a linear extension of one expansion strut in one serpentine band and extends adjacent to a closed end in the same direction as the one expansion strut in the one serpentine band, a channel formed between the first end of the one expansion strut and the closed end adjacent thereto, and the second end of the connection member forms a linear extension of the one expansion strut in the another serpentine band and extends adjacent to a closed end in the same direction as the one expansion strut in the another serpentine band, a channel formed between the second end of the one expansion strut and the closed end adjacent thereto. - View Dependent Claims (7, 8, 9, 10)

11. A stent comprising:
-
a plurality of expansion struts including longer expansion struts and shorter expansion struts, longer and shorter expansion struts which are adjacent one another connected one to the other to form loops, and connection members, each connection member having a first end extending from one expansion strut, a second end extending from another expansion strut and connecting two loops, wherein the first and second ends are circumferentially and longitudinally offset from one another. - View Dependent Claims (12, 13, 14, 15)
