Visual and dimensional analysis was performed on the returned devices.The reported difficulty removing was unable to be confirmed as the returned guidewire was able to be fully advanced through the returned catheter, with no resistance noted.The dragonfly guidewire exit notch was noted to be stretched distally for a length of 1mm.The returned guidewire was noted to be bent 40mm away from the distal end, which can contribute to difficulty removing.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 similar complaints reported from this lot.Based on the information received and analysis of the returned device, the investigation determined that the reported difficulties were due to operational context.It is likely that during the procedure the guidewire being used with the catheter was inadvertently bent, as observed, and caused the difficulty removing the catheter; however, this could not be confirmed.The stretched guidewire exit notch also suggests difficulty removing, and that the guidewire and catheter were likely spread apart during removal; however, this could also not be confirmed.The returned guidewire was able to be fully inserted through the catheter minirail without any resistance or anomalies.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
