1. A stent comprising:
- a stent body defining a length and comprising a plurality of cells,each cell comprising two structural members extending in an undulating pattern, andeach structural member comprising a plurality of cell segments defining a plurality of nodes therebetween,wherein an inner of edge of at least one node of the plurality of nodes defines a non-constant radius of curvature;
wherein the inner edge of the at least one node includes a first inner portion defining a first radius of curvature and a second inner portion defining a second radius of curvature, and wherein the first radius of curvature and second radius of curvature are different.
