Abstract
The matched end stiffness stent system and method of manufacture includes a stent delivery system including a catheter, balloon, and stent. The stent includes a wire bent into a waveform having a constant frequency and wrapped into a hollow cylindrical shape, the wire having a body portion having body struts connected between body crowns, the body struts having substantially equal lengths, and the waveform in the body portion having a constant amplitude; and at least one end portion attached to the body portion, the at least one end portion having end struts connected between end crowns, the waveform in the at least one end portion having an amplitude different from the constant amplitude of the waveform in the body portion. The cross sections of the end struts are selected so that the body struts and the end struts have a substantially equal stiffnesses in response to an applied load.
