1. A radially expandable, tubular stent defining a longitudinal axis in an axial direction of the length of the stent, comprising:
repeating pairs of axial rings, the axial rings each comprising repeating struts in a repeating zig-zag pattern;
first connecting struts;
second connecting struts,
wherein the axial rings of respective ones of the repeating pairs of axial rings are connected by respective ones of the first connecting struts repeating periodically and circumferentially such that the first connecting struts are evenly spaced around a circumference of the stent,
wherein adjacent ones of the repeating pairs of the axial rings are connected by respective ones of the second connecting struts, wherein the second connecting struts are grouped together so as to be unevenly spaced around the circumference of the stent,
wherein a stent wall defined by the pairs of axial rings and the first and second connecting struts includes a first longitudinally extending section which includes some of the first connection struts and is devoid of the second connecting struts, and a second longitudinally extending section which includes a remainder of the first connecting struts and the grouped together second connecting struts.
