    摘要： Apparatus and methods for delivering stents or stent segments to body lumens include one or more tubular prostheses carried at the distal end of a catheter shaft, a sheath slidably disposed over the prostheses, and a guidewire tube extending from within the sheath to the exterior of the sheath through an exit port in a sidewall thereof. A guidewire extends slidably through the guidewire tube. The sheath can be moved relative to the catheter shaft and the guidewire tube to expose the prostheses for deployment. Mechanisms are described for measuring the distance that the sheath is moved relative to the catheter shaft and/or the guidewire tube, or for counting the number of stents exposed and/or deployed by operation of the device. These mechanisms include optical counting mechanisms, inductive, resistive, and/or magnetic resonating counters, electrical contact counters, and mechanical counters.
