A review of the subject device dhr confirmed that the subject device was manufactured and tested according to relevant procedures, tested before release, and shipped according to manufacturer's specifications.The system was manufactured on 16-sep-2020 and installed at the customer's site on 22-dec-2020.A review of subject device product risk file (rd-1124690_ak) revealed risk # 2.4.2; "system failure" which has the potential to lead to prolonged procedure -or- ineffective treatment which may require re-operation.The risk likelihood has been quantified and found to be remote, and the risk has been characterized and documented as acceptable within a full risk assessment.A lumenis service engineer visited the site five (5) days after the reported event and confirmed errors 208, and 266.The engineer replaced the charger calibrated voltages through the hv pmcu, added water and after testing the system, it was returned to the facility having met manufacturer's specifications.A two year historical review of similar complaints revealed that the same malfunction of errors 208, and 266 has not led to serious injury in the past.Although the device malfunction did not cause or contribute to any change in the patient's condition, it is uncertain if the user facility had to use an alternate laser device as intervention to prevent serious injury.In an abundance of caution, lumenis is reporting this malfunction.The faulty part is expected to be returned to the manufacturer for evaluation.Upon receipt and completion of the failure analysis of the complaint device, if the conclusion will be changed due to the analysis, lumenis will file a follow-up mdr.Lumenis will continue to monitor this failure mode; complaint trending will continue to monitor per global complaint handling sop ((b)(4)) and per post marketing surveillance procedure ((b)(4)).
