1. A stent, the stent comprising:
- a first circumferential ring, a second circumferential ring, and a third circumferential ring, adjacent circumferential rings forming a first ring pair and a second ring pair, each circumferential ring comprising a plurality of struts;
a first peak to valley connector, and a second peak to valley connector, the peak to valley connectors each engaging the first ring pair, the peak to valley connectors each having a first end, each of the first ends of the peak to valley connectors separated by a first number of struts in a first circumferential direction; and
a first peak to peak connector, and a second peak to peak connector, the peak to peak connectors each engaging the second ring pair, the peak to peak connectors each having a first end, each of the first ends of the peak to peak connectors separated by a second number of struts in the first circumferential direction.
