Abstract
A method for forming a wave form for a stent. The wave form includes a plurality of substantially straight portions and a plurality of curved portions. Each curved portion connects adjacent substantially straight portions. The method includes feeding a formable material between a first die and a second die, the first die having a protruding surface in the shape of the wave form, and the second die having a recessed surface in the shape of the wave form complementing the protruding surface of the first die, pressing the formable material with the protruding surface of the first die into contact with the recessed surface of the second die, and shearing the wave form from the formable material with shearing forces created by the pressing.
