Visual analysis and additional testing were performed on the returned device.The reported difficulty removing the catheter and imaging loss (alleged lens damage) were unable to be confirmed due to returned condition of the device and the operational context of the reported issues; however, the reported kink was able to be confirmed.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.A query of the complaint handling database for the reported lot was performed and revealed there is no indication of a lot level quality product issue.The investigation determined that the difficulty removing the catheter, catheter damage (kinks), and imaging loss were due to operational context.There were several kinks noted to the returned catheter sheath in the distal portion, which is suggests there was difficulty using the catheter.It is likely that the observed damage (multiple kinks) to the returned catheter contributed or caused the reported removing the catheter.The reported imaging loss (alleged lens damage) was unable to be confirmed as the optical fiber of the returned device was confirmed to have remained intact.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
