A helical stent includes a central segment having a first tubular waveform and a first end segment having a second tubular waveform. The waveforms are defined by a plurality of struts and a plurality of crowns connecting adjacent struts together. The struts of the second tubular waveform have different lengths such that second tubular waveform includes a plurality of amplitudes. The second tubular waveform comprises a complete turn around a longitudinal axis of the stent. A first connector connects together the first tubular waveform first end, the second tubular waveform first end, and the second tubular waveform second end. Due to the configuration of the second tubular waveform of the first end segment, the stent end at the first end segment is substantially orthogonal to the longitudinal axis of the stent. A second end segment similar to the first end segment can be connected to a second end of the first tubular waveform.
