PWR PAIR

Additional Manufacturer Narrative

TECHNICAL EVALUATION SUMMARY: ON SEPTEMBER 19TH 2025, AS SOON AS THE DEVICE WAS RETURNED BY THE CUSTOMER, MECTRON'S TECHNICAL SERVICE LABORATORY CONDUCTED A FULL EVALUATION OF THE PWR PAIR UNIT SERIAL (B)(6) AND ASSOCIATED HANDPIECES. THE FOLLOWING RESULTS WERE OBTAINED: · PWR PAIR ELECTRICAL SAFETY TEST: PASSED SUCCESSFULLY. · PWR AIR PERIO HANDPIECE SERIAL (B)(6): - PRESSURE PROPHY MODE: 3.45 BAR (REFERENCE VALUE: 3.5 BAR +/- 0.1). - PRESSURE PERIO MODE: 2.1 BAR (REFERENCE VALUE: 2.7 BAR +/- 0.1). · PWR PIEZO LED HANDPIECE SERIAL (B)(6): - ARRIVED NON-FUNCTIONAL, SHOWING NO INSERT TUNING AND ZERO INSULATION. EVALUATION: PRESSURE PERIO MODE DEVIATION OF PWR AIR PERIO HANDPIECE IS NOT CONSISTENT WITH THE REPORTED EVENT. IN FACT, THE REDUCED MEASURED PRESSURE, WOULD REDUCE THE RISK OF COMPLICATIONS OF AIR PROPHYLAXIS TREATMENTS. THE SCALER PWR PIEZO LED HANDPIECE CONDITION IS LIKELY DUE TO POST-EVENT USAGE OR DAMAGE DURING TRANSPORT. NO OTHER PROBLEMS OR MULFUNCTIONS WERE DETECTABLE. CLINICAL EVALUATION & CONCLUSION: DESPITE MULTIPLE FOLLOW-UP ATTEMPTS, THE PATIENT DECLINED TO PROVIDE FURTHER DIAGNOSTIC DETAILS REGARDING THE SUSPECTED AIREMBOLISM. THE ONLY AVAILABLE CLINICAL INFORMATION INCLUDES REPORTED SWELLING ON THE LEFT SIDE OF THE FACE, EYE, AND NECK. DUE TO THE LACK OF CONFIRMED MEDICAL DIAGNOSIS AND THE ABSENCE OF INSTRUMENTAL EVIDENCE, NO DEFINITIVE CONCLUSION CAN BE DRAWN REGARDING THE NATURE OF THE ADVERSE EVENT. FURTHERMORE, BASED ON THE TECHNICAL EVALUATION AND THE AVAILABLE USAGE DATA, NO CAUSAL RELATIONSHIP CAN BE ESTABLISHED BETWEEN THE ADVERSE EVENT AND THE MEDICAL DEVICE OR ITS METHOD OF USE.
