Additional information: h6 (component code, type of investigation, investigation findings, investigation conclusions).Results of investigation: the device was returned for evaluation.Visual inspection noted no issues.Functional evaluation found that the device operated as intended with no faults found.Reported noise or vibration was not replicated in testing or during device servicing, so no probable cause can be determined.A documentation review was performed.Manufacturing records.A review of device manufacturing records found no abnormalities were reported on this device during manufacture that would have contributed to the reported event.The relevant risk files pertaining to this device have been reviewed and contains details relating to abnormal mechanical noise and decreased performance.The risk has been anticipated and adequately mitigated, with a revision of the risk file not required.Historical data analysis a review of previous complaints found other complaints relating to vibration or noise produced by a versajet console.There are no previous escalations raised in relation to versajet consoles being reported to vibrate or make noise during operation.No manufacturing, design or labelling deficiencies have been confirmed to have contributed to this failure mode in other complaints.Factors that may have contributed to the reported failure may be that console required general servicing, or that the saline supply was left to empty, allowing air into the fluid line.This would inhibit the consoles ability to provide flow of saline, exerting stress on the pump, causing vibration/noise.The device instructions for use highlights the importance of ensuring this does not occur, as air in the supply tube can lower device efficiency and would require re-priming.No manufacturing quality concerns have been observed, therefore no corrective actions are deemed necessary, smith and nephew will continue to monitor for adverse trends relating to the reported allegation.Corrected data: d9, h3 (device was returned to manufacturer), h6 (health effect - impact code), h8.
