Balt usa's reference number: (b)(4).The analysis of the complaint was performed by supplier balt extrusion for deeper investigation, summary provided as follows: the affected catheter eclipse2l has not been returned to balt extrusion sas for inspection.As a result, the analysis of the reported event was limited.The review was based on the incident description, the device history records, and the data gathered during our post-marketing surveillance program for such failures.The lot history records (lhrs) review for this specific batch number did not highlight any anomaly during the manufacturing process.Several tests were performed during the manufacturing process: the braid, the tube, and the balloon are 100% controlled with a visual inspection ; a tightness test of the balloon is also performed on every unit ; the integrity of the micro-catheters is 100% controlled ; the hydrophilic coating appearance and cleanliness are 100% controlled ; a sliding test is also performed on a sample of microcatheters ; the rings are 100% controlled.There is no other complaint registered on this lot number to date.The incident description mentioned that after the injection of the embolic agent, the eclipse2l revealed being entrapped into this ("[.] sensitive fusiform basilar aneurysm that was slowly sacrificing with a liquid embolic.Once the embolization was complete, he lightly pulled on the eclipse without successful removal").By correlating this information with our post-marketing surveillance program, such blockages are generally caused by the embolic agent reflux beyond the catheter's distal extremity during the injection.So, this incident type is unlikely linked to the device itself.In conclusion, the incident reported (catheter trapping) cannot be linked to a potential technical failure of the balloon catheter eclipse2l.Manufacturing records complied with specifications, and the product was not available for inspection.The trend of this failure mode will continue to be monitored as part of our post-marketing surveillance program.Review of the lot history records did not reveal any in-process or lot-specific issue that could account for the observation.No additional complaints against lot number f211200089 has been made for the same issue.Comprehensive analysis of this failure mode has remained subject to monitoring for any unacceptable increase in trend.The submission of this report or related information to the fda, and its release by fda, does not reflect a conclusion by the party submitting this report of the fda that the report or related information is an admission that the manufacturer, their employees, or the device caused or contributed to the reportable event.
