Additional Manufacturer Narrative
One accumax 550 laser fiber was received for evaluation.Visual examination revealed that the exposed glass fiber tip measured approximately 3.5 mm and appeared used.Additional examination under magnification revealed that the pattern on the tip face was consistent with a slight degradation.There was no damage along the body of the fiber and there was no evidence of a misfire near the connector.Visual examination of the fiber face within the sma connector under magnification revealed that there was debris on the fiber face and that only a small amount of light was coming through.The condition of the returned device would cause the device to emit insufficient energy transmission during ablation thereby confirming the event.The noted damages indicate difficulty was experienced during the procedure and was likely due to anatomical or procedural factors such as tortuous anatomy or maneuvering of the device.Therefore, a review and analysis of all available information indicated that the most probable root cause is operational context.A review of the device history record (dhr) was performed; no anomalies were noted.A search of the complaint database revealed that no similar complaints exist for the specified lot.
