Exemption number e2019001.(b)(4).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.The investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that during removal interaction with the introducer sheath resulted in the reported difficulty to remove.Manipulation of the device ultimately resulted in the reported material separation.It should be noted that the hi-torque turntrac guide wire instructions for use states: do not: push, auger, withdraw, or torque a guide wire that meets resistance.If resistance is observed at any time, determine the cause under fluoroscopy and take remedial action as needed.Although it was noted that resistance was noted during removal of the guide wire, this was due to the guidewire being caught in the introducer sheath therefore the force applied during removal of the device seemed to be a reasonable clinical response to the difficulties.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported the procedure was performed to treat a lesion in right coronary artery.The turntrac guide wire kinked when exiting the guide catheter and when removing the turntrac guide wire, the guide wire got caught in the introducer sheath.Force was used during removal and the guide wire was withdrawn.Once outside of the anatomy, the tip of the guide wire was noted to have separated in two pieces, at the radiopaque marker.A new turntrac guide wire was used successfully to complete the procedure without issue.There were no adverse patient effects.There was no clinically significant delay in the procedure.No additional information was provided.
