Claim Text:
1. A stent for implantation in a body vessel, the stent comprising: a circumferential element comprising a first long length side, a second long length side, a first short length side, and a second short length side, the first long length side being substantially parallel to and spaced across from the second long length side and the first short length side being substantially parallel to and spaced across from the second short length side; where the first long length side has a longitudinal length about equal to the second long length side and the first short length side has a longitudinal length about equal to the second short length side; where each of the sides comprises a plurality of struts of varying longitudinal lengths circumferentially connecting the first long length side, the first short length side, the second long length side and the second short length side; where the strut longitudinal lengths of the first and second long length sides are greater than the first and second short length sides strut longitudinal lengths; wherein the struts of the circumferential element each comprise a diameter, and the struts of the first and second long length sides have a diameter less than the diameter of the struts of the first and second short length sides; and where the diameters of the struts decrease from the first and second short length sides to the first and second long length sides, as the lengths of the struts increase, and where the rate of change in strut diameter per change in strut longitudinal length is substantially linear, such that the circumferential element a substantially constant outward radial force about the element circumference.
