Abstract
A stent delivery system for dynamic deployment of a stent loaded thereon and a method of manufacturing the system. The stent delivery system includes a balloon catheter with a balloon in a spirally twisted delivery configuration on which a stent is crimped or otherwise loaded. The stent is made from a single, continuous strand of wire formed into a sinusoidal waveform that is wrapped into a helical pattern and joined at selected crowns. Upon inflation of the spirally twisted balloon of the stent delivery system, the stent undergoes dynamic deployment such that the stent in a deployed or expanded configuration has crowns with obtuse deployment angles and crowns with acute deployment angles.
