It was reported that the procedure was performed to treat a chronic total occlusion (cto) in the posterior tibial artery with moderate calcification, heavy tortuosity and 100% stenosis.The ht command 14 guide wire crossed the lesion from the anterior tibial artery (ata) via retrograde approach, but an unspecified balloon catheter failed to cross the lesion.Therefore, the ht command 14 was being removed, but the tip became stuck in the lesion.A non-abbott micro catheter was replaced with another.018 non-abbott catheter to remove the guide wire.Force was applied; however, the tip was separated and remains in the patient's anatomy.The tip was possibly embedded in the lesion, but this could not be confirmed.There were no adverse patient sequela.No additional information was provided.

A visual inspection was performed on the returned device.The reported material separation could not be tested due to the device condition.The reported entrapment of device could not be tested as it was based on operational context.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 similar incidents from this lot.It was reported that a force was applied during removal of the guide wire from the anatomy.It should be noted that the command es instructions for use states: ¿do not push, auger, withdraw, or torque a guide wire that meets excessive resistance.¿ in this case, it was noted that the guide wire encountered resistance with the lesion during removal, therefore, the force applied during removal seems to be a reasonable clinical response to the difficulties.The investigation determined the reported difficulties and subsequent treatment appear to be related to the operational context of the procedure.In this case, it was noted that the guide wire interacted with the moderately calcified, heavily tortuous, and 100% stenosed lesion, resulting in the reported entrapment.Manipulation of the entrapped wire, as use of force was noted, likely resulted in the reported material separation.The separated portion of the guide wire was possibly embedded in the lesion, but this could not be confirmed.There is no indication of a product quality issue with respect to manufacture, design, or labeling.
