A two year historical review of similar complaints revealed no events involving lumenis fibers and patients having been injured due to fiber fragmentation in the patient's anatomy.To date lumenis is unaware of such events ever having been reported.A review of subject device risk management files ((b)(4)) revealed that fiber breaks inside the body is a recognized risk which has been quantified and found to be negligibly small.The risk has been characterized and documented as acceptable within a full risk assessment.While the information received does not confirm that a serious injury had occurred, it is uncertain if the event would likely cause or contribute to a serious injury if the malfunction were to recur; therefore, lumenis is reporting this malfunction in an abundance of caution.The complainant indicated that the devices have been disposed of and will not be returned for evaluation; therefore, a failure analysis of the complaint device could not be completed.If any further relevant information is identified, a supplemental medwatch will be filed.
