Manufacturer¿s ref.No: pc-(b)(4).The purpose of this mdr submission is to report the investigational finding of the returned device.[conclusion]: the healthcare professional reported that during a primary in-office eustachian tube balloon dilation procedure, the tip of the of the acclarent pivot navigation balloon dilation system (pvt0616n / (b)(6).) fell off before the procedure started.The balloon was being advanced to make sure it was working properly as it exited the guide catheter.The pivot navigation balloon was replaced and the procedure was started.There were no report of any patient adverse event or complication.On 07-jun-2022, additional information was received.The information indicated that the blue bulb tip of the pivot device fell off.The balloon component was never inflated.There was no damage noted on any of the device components prior to the advancement of the balloon.There was no resistance / friction felt when the balloon was being advanced.The reported issue did not result in any clinically significant delay in the procedure.The complaint device was returned for evaluation and analysis.The investigational finding is documented below.Investigation summary: a non-sterile acclarent pivot navigation balloon was received.Visual inspection was performed.It was observed that the blue bulb tip was missing from the distal tip, and it was not returned for analysis.Additionally, guidewire was removed from the device and was not returned from analysis.Device was inspected under microscope and no residues from the blue bulb tip were noted.Due to this issue a supplier manufacturing investigation was performed.Based on the evidence available, it was concluded that the tip detachment failure is caused by the following reasons: -shape of the distal tip, the shape of the tip obtained from the laser welding process allows the tip to become detached during use when subject of extra handling.-test method not representative, the pull test method used for lot release was not able to detect a distal tip not totally attached to the balloon catheter.The reported issue documented in the complaint was confirmed based on the conditions of the device.It should be noted that product failure could be caused by multiple factors.However, corrective actions to solve this failure mode were already implemented through confluent¿s quality system.The corrective actions were also challenged and validated through a performance qualification.A review of manufacturing documentation associated with this lot ((b)(6).) presented no issues during the manufacturing or inspection processes related to the reported complaint.There were no nonconformances related to device manufacture or inspection.All product rejected during manufacturing was identified as scrap and properly accounted for.A manufacturing record evaluation was performed and no non-conformances related to the complaint were found during the review.As part of acclarent quality process all devices are manufactured, inspected, and released to approved specifications.As part of the post market surveillance program, information from this complaint is trended for statistical signals and corrective / preventive action may be triggered at a later time.Since there was no evidence to suggest the event was related to a manufacturing or design issue, no corrective actions will be taken at this time.Updated sections: b.4, g.3, g.6.H.2, h.3, h.6, and h.10.The manufacturer will submit a supplemental report if new facts arise which materially alter information submitted in a previous mdr report.Additional information will be submitted within 30 days of receipt.
