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 14-nov-2018 and installed at the customers site on (b)(6) 2016.A lumenis service engineer visited the site after the reported event and examined the device.Verified reported fault 49, replaced laser deck board and performed pyro calibration and after reconfirming its operation, the engineer returned the system to the facility in a working order.A review of historical product complaints from the past two years shows that the same malfunction of pyro error has not led to serious injury.A review of system risk files (1003215 rev h) revealed risk #2.1.2 "laser output measurement failure (e.G.Pyro detectors failure)" which have the potential to lead to ineffective treatment which may require re-operation -or- prolonged procedure.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.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 method as intervention to prevent permanent damage.In an abundance of caution, lumenis is reporting this malfunction.According to the gso expert, the pyro sensors are sensitive to movement and a calibration error is likely to happen during local transportation.Lumenis is closing this complaint, but 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)).
