A visual inspection of the catheter sample revealed both extensions were cut 1.5cm from the hub.The venous lumen tip is missing and was not returned.A review of the manufacturing records indicated that all device specifications and quality requirements were satisfied.The venous lumen tip was measured.All measurements were within the design specifications.There is no evidence of swelling, crumbling, discoloration, degradation or polymer variation of the lumen material.There is no evidence of a manufacturing problem.The device was implanted in (b)(6) 2015 and the missing tip was an "accidental finding on chest x-ray done (b)(6) 2015".There is no way to determine when the tip of the catheter broke off.It is unlikely that the tip spontaneously broke off unless it was damaged during the insertion procedure.We are unable to determine the root cause of this event.
