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 revealed no other similar incidents.Based on the information provided, the reported difficulty appears to be due to circumstances of the procedure.It is likely that the dragonfly catheter was inadvertently damaged while attempting to maneuver the device under challenging anatomical conditions.Furthermore, the kink on the dragonfly may have caused resistance between the guidewire and the dragonfly contributing to the difficulties removing the device, however, this could not be confirmed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.The bmw elite ii guide wire referenced in is filed under a separate medwatch report number.
