It was reported that an absolute pro stent delivery system advanced to the right external iliac artery without issue.During stent deployment, there was no issue noted, however the stent jumped distal to the lesion.The stent was deployed completely outside the target lesion site requiring additional balloon angioplasty to fully appose the stent to the vessel wall.Following, a sheath was unable to pass through the distal stent.There were no adverse patient effects and there was no clinically significant delay.There was no additional information provided regarding this issue.
