The device was not returned for analysis.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no other incidents from this lot.It is possible that as the stent was being deployed interaction with the anatomy and/or the delivery system was slightly pushed distally as the stent was being deployed resulting in the reported malposition of device (stent jumped into the aorta); however, this could not be confirmed.The investigation determined a conclusive cause for the reported difficulties cannot be determined.The treatment appears to be related to the operational context of the procedure as the stent was snared and an omnilink stent was implanted without further issue to complete the procedure.There is no indication of a product quality issue with respect to manufacture, design or labeling.
