(b)(4): the 89-6110 complaint device was not returned for evaluation.Attempts had been made to retrieve the instrument and get additional information by our customer advocacy team but were told the device was not releasable and no new information was provided.Based on the provided information that the device was sent into bd¿s repair department on september 10 2015, we were able to review the repair records and identify the product name, code, date code, and lot number; therefore, a dhr review could be performed.Note the device was from july 2004 which makes the instrument 12 years old.In addition, it was found to have been repaired twice before by bd, once in 2012 under repair # (b)(4) for a broken cable and again in 2015 under repair # (b)(4) for a replacement end segment (long tube).Since this device is 12 years old there was an initial concern that the device did not receive some of the improvements to the product design the device has undergone through the years.The repair record in 2012 confirmed the device was repaired to the 2006 improvement of the addition of the nipple feature of the nitinol wire which aided in the prevention of the segments disassembling for the part in the event of a failure.From the provided information it was stated that the wire was protruding out and had lacerated the liver.Historically, these typical failures are indicative of the nitinol wire breaking at the point of retraction or bend out the side of the flexible shaft due to some type of overstress.Bd is unable to determine exactly where and how the device broke since the device was not returned.Without the device to confirm and evaluate the reported failure carefusion is unable to determine the root cause.If the device becomes available the complaint will be re-opened and a more thorough investigation will be performed.A review of the device history record did not reveal any non-conformances.The device passed all acceptance criteria for release.Since the complaint sample was not returned for evaluation, and there is no trend detected for this issue, no further action will be required at this time.Bd will continue to trend and monitor for this reported failure and for this product family.
