On (b)(6) 2016, two 10mm x 10cm gore viabahn® endoprostheses were to be implanted for treatment of occlusion of both common iliac arteries by kissing technique.Both devices were accessed through the 11f cook sheaths and advanced via supercore stiff guide wires.There was no resistance when advancing the devices to the target lesion and initiating deployment.The first 10mm x 10cm device was accessed from the left common femoral artery and successfully deployed in the left common iliac artery.During deployment of the second 10mm x 10cm device ((b)(4)) in the right common iliac artery, it was reported the deployment line got stuck when approximately 2-3cm endoprosthesis not been expanded and the deployment could not continue.The physician carefully retracted the delivery system and pulled the olive tip through the remaining constrained device, thereby completing deployment.However, the deployment line could not be released from the device.The physician cut the deployment line to remove the catheter and approximately 20cm of deployment line remained in the patient.To avoid any thrombosis caused by the deployment line remaining inside, the physician decided to implant a 10mm x 15cm gore viabahn® endoprosthesis ((b)(4)) in the right common iliac artery to pin the deployment line segment to the vessel wall.
