1. A method of making a stent comprising the steps of:

  • loading one or more connecting rings onto a wire such that the wire is disposed through a lumen of each connecting ring;

    forming the wire into a zigzag waveform defined by a series of generally straight segments interconnected by crowns;

    helically winding the waveform into a generally tubular configuration having a plurality of helical bands such that a crown of a first band is rotatably disposed within a lumen of one of the connecting rings and a crown of a second band adjacent the first band is disposed abutting an exterior surface of the connecting ring; and

    fusing the exterior surface of the connecting ring to the crown of the second band to form a rotatable connection between the first band and the second band.
