The device was not returned for evaluation.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 complaints reported from this lot.Based on the information provided, a definitive cause for the resistance and stent dislodgment could not be determined.It may be possible that the protective sheath caught on the dispenser coil during removal resulting in the reported resistance and causing the stent to dislodge from the balloon; however, this could not be confirmed.
