It was reported that during the procedure, the pressurewire x wireless device was being advanced to the lesion in the left anterior descending (lad) artery.During advancement, the pressurewire became stuck in an implanted stent strut and could no longer be advanced.The pressurewire was then attempted to be removed; however, the devices were stuck together, and the distal tip of the pressurewire separated in the anatomy.The separated tip was removed from the vessel with a guideliner.Another pressurewire x wireless device was used successfully for the procedure.There was no adverse patient sequela and no reported clinically significant delay in the procedure or therapy.No additional information was provided.

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 similar complaints reported from this lot.Based on the reported information, the reported failure to advance, difficulty removing, and material separation resulting in unexpected medical intervention to retrieve the separated tip using a guideliner appear to be related to the circumstances of the procedure.It is likely that the reported failure to advance, difficulty removing, and tip separation was due to interaction with the previously implanted stent.It is likely that the pressurewire tip became stuck with the implanted stent causing separation during removal.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
