Manufacturer Narrative
|
Block d4, h4: the complainant was unable to provide the suspect device lot number; therefore, the lot expiration and device manufacture dates are unknown.Block h6: medical device problem code a0401 captures the reportable event of guide catheter break.Impact code f23 captures the reportable event of unexpected medical intervention.Block h10: the returned flexima rx biliary stent was analyzed, and a visual evaluation noted that the push catheter was kinked at distal end.The guide catheter was detached from the delivery system, it was visually inspected and it was kinked in some locations.If the guide catheter detaches from the delivery system, the stent will fall from the delivery system as well.No other issues with the device were noted.The reported event was confirmed.According to the product analysis, this device met all manufacturing requirements and no abnormalities were reported during the manufacturing process.It is most likely that procedural or anatomical factors encountered during procedure could have affected the device performance and its integrity.Handling and manipulation of the device during its use can lead to kink/bend the catheters, user technique when the device is removed from its package or advancing the device through the scope can kink the catheters, this condition can cause friction between the components at kinked/bent areas in the catheters, force retracting the pull wire/guide catheter in order to release the stent can result in guide catheter breaking, making that the stent falls from the delivery system as well.Therefore, adverse event related to procedure is selected as the most probable root cause for the complaint.Block h11: correction to block a2: age at time of event; unit of measure - age.
