ABSTRACT:
A stent comprises a plurality of adjacent cylindrical elements defining a first end section, a second end section, and a center section therebetween. Each cylindrical element has constant thickness struts formed in a generally serpentine wave pattern transverse to the longitudinal axis which contains alternating valley portions and peak portions. A plurality of interconnecting members extend between the adjacent cylindrical elements and connect the adjacent cylindrical elements to one another. The cylindrical elements are formed of a stent material, the composition of which is uniform throughout the stent. The stent material of the struts in each of the first end section and the second end section have a greater mass than the stent material of the struts of the center section.
