First Claim
1. A stent comprisinga plurality of strut pairs, each strut pair comprising a first strut and a second strut, each strut having an outer surface and an inner surface, each first strut having a first length and a first number of cavities extending from the outer surface through the inner surface, each second strut having a second length and a second number of cavities extending from the outer surface through the inner surface, the first length being greater than the second length, the first number of cavities being greater than the second number of cavities;
- a plurality of connectors, each connector extending between a first strut of a first strut pair and a first strut of a second strut pair.

Abstract
An expandable stent includes a tubular structure with an outer surface positionable adjacent to a vessel wall and an inner surface facing a lumen of a body passageway. The tubular structure further includes a plurality of expansion struts, connector struts and cells. The tubular structure has a first diameter which permits intraluminal delivery of the tubular structure into the body passageway, and a second expanded and deformed diameter which is achieved upon the application of a radially, outwardly extending force. A plurality of cavities are formed in the outer surface of the stent.
