1. A continuous wire stent including a radially compressed configuration and the radially expanded configuration, the continuous wire stent in the radially compressed configuration comprising:
a wire bent into a waveform and spirally wrapped into a helix having a plurality of bands that form a hollow cylindrical shape, at least a portion of the helix including a plurality of repeating body units including a plurality of waves including
a first outer crown including a first intrados and a first outer crown center,
a second outer crown including a second intrados facing the first intrados and a second outer crown center,
a first mid-crown disposed between the first outer crown and a second mid-crown, the second mid-crown being disposed between the first mid-crown and the second outer crown, the first mid-crown including a first mid-crown center and the second mid-crown including a second mid-crown center,
a first strut connecting the first outer crown to the first mid-crown,
a second strut connecting the first mid-crown to the second mid-crown,
a third strut connecting the second mid-crown to the second outer crown,
a third mid-crown disposed between the second outer crown and a fourth mid-crown, the fourth mid-crown being disposed between the third mid-crown and a next outer crown in a next wave of the waveform, the third mid-crown including a third mid-crown center and the fourth mid-crown including a fourth mid-crown center,
a fourth strut connecting the second outer crown to the third mid-crown,
a fifth strut connecting the third mid-crown to the fourth mid-crown, and
a sixth strut connecting fourth mid-crown to the outer crown in the next wave of the waveform, the next outer crown including a next outer crown center,
wherein in the radially compressed configuration, the second outer crown center, the third mid-crown center, the fourth mid-crown center, and the next outer crown center are co-linear on a line that is parallel to a central longitudinal axis of the continuous wire stent.
