Visual analysis was performed on the returned device.The reported difficulty removing was unable to be confirmed due to the condition of the returned unit.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 revealed no other similar complaints reported from this lot.The investigation determined that the reported difficulties were likely due to procedural circumstances.Based on the evaluation of the returned unit, it is likely that during use, the clearance between the bmw guidewire and guidewire lumen of the dragonfly optis was reduced causing friction between the devices resulting in difficulty removing.Additionally, the stretched and torn guidewire exit notch on the returned dragonfly catheter and damage to the bmw tip coils likely occurred during the attempt to remove the catheter from the wire.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
