Lumenis investigated the reported event.The foreign facility had reported that during a laser lithotripsy for kidney stone procedure in which a lumenis versapulse powersuite 60w laser system was being utilized, the system stopped working.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 (b)(6) 2018 and installed at the customers site on (b)(6) 2020.A lumenis service engineer visited the site one (1) day after the reported event and examined the laser system.The engineer found first 45 mirror damaged and replaced it, adjusted the three-way optical path, cleaned the optical fiber hole and lens.Performed energy check and after verifying that the system is working within manufacturer specifications the system was returned to the facility safe and ready for use.A review of historical product complaints from the past two years shows that the same malfunction of mirror failure has not led to serious injury.To date lumenis is unaware of such events ever having led to injury.A review of system risk files (doc (b)(4) rev c) revealed risk #2.13; 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 full risk assessment.The last preventive maintenance was done on (b)(6) 2021 while the event happened on (b)(6) 2022.A review of subject labeling, (0637-117-01 rev.R versapulse powersuite op manual) revealed in the annual laser maintenance "preventative maintenance, safety, power, and calibration checks should be performed annually by a lumenis-certified service engineer to ensure proper laser performance" according to the gso expert this event could have been avoided if the preventive maintenance was done on time.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 the alternate device as intervention to prevent permanent damage.In an abundance of caution, lumenis is reporting this malfunction to the fda.Unrelated to the event, lumenis has initiated capa (b)(4) to further investigate various optical issues with the holmium product family lasers.This complaint is being closed to capa (b)(4), and therefore follow-up mdr is not required.Lumenis will continue to monitor this failure mode; complaint trending will continue to monitor per global complaint handling sop doc no.(b)(4).And per post marketing surveillance procedure doc no.(b)(4).
