1. A method of manufacturing a stent delivery system for dynamic deployment of a stent comprising:

  • twisting an uninflated balloon of a stent delivery catheter into a spirally twisted delivery configuration; and

    loading a stent onto the spirally twisted balloon, the stent being made from a single, continuous strand of wire formed into a sinusoidal waveform that defines crowns and struts of the stent, the sinusoidal waveform having been wrapped into a helical pattern and joined at selected crowns to form the stent,inflating the balloon, wherein the spirally twisted balloon untwists upon inflation and thereby applies a twisting force to the stent such that the stent undergoes dynamic deployment, andwherein the stent in a deployed configuration after dynamic deployment has crowns with obtuse deployment angles and crowns with acute deployment angles.
