This report is being supplemented to provide additional information based on the approved final investigation.Sections b5 and g2 were corrected with information that was inadvertently left out of the initial report.A review of the device history record found no deviations that could have caused or contributed to the reported issue.Based on the results of the investigation, the definitive root cause of the band deployment issue could not be determined.It is possible that the phenomenon occurred due to improper usage of the ring applicator, or inadvertent use.The instruction manual identifies the following verbiage, which may have prevented the phenomenon: ¿improper use of the applicator may result in falope-ring bands being inadvertently discharged into the peritoneal cavity or entrapping the fallopian tube within the applicator forceps tongs." three attempts were performed to obtain additional information, but no response was received from the customer.Olympus will continue to monitor field performance for this device.
