Abstract: A stent deployment system includes a delivery catheter, a dilation balloon disposed at the distal end of the delivery catheter, and a stent deployment mechanism disposed at a predetermined distance from the dilation balloon. The delivery catheter includes a plurality of markers at the proximal end that are used to gauge the movement of the delivery catheter and to align the dilation balloon and stent deployment mechanism with a target region in a vessel, such as a lesion or blocked region. The stent deployment method includes introducing the delivery catheter into the vessel until the dilation balloon is aligned with the target region, and inflating the dilation balloon to predilate the target region. The delivery catheter is then advanced until the stent deployment mechanism is aligned with the predilated target region using the markers on the proximal end of the delivery catheter.
