Device evaluated by mfr: the device was returned for evaluation.The advancer, drive shaft, and handshake connection were visually and microscopically examined.Inspection of the device revealed no damages or defects.Functional testing was initially performed by connecting the returned advancer to the liquid infusion line.When liquid was advanced through the device, a light drip at the advancer body was noted as intended by design.There were no abnormal fluid leaks identified during functional testing.Further functional testing was performed by attempting to rotate the drive shaft and the drive shaft was able to be rotated with no issue.Then functional testing was performed by connecting the advancer to the rotablator control console system.When the foot pedal was pressed, the advancer stalled and would not run.The sound of air escaping the device could be heard during the device stall.In order to determine the cause for the stall, destructive testing was performed, in which the advancer was dismantled and the interior components were inspected for damages or defects.Destructive testing was unable to identify the cause of the stall.Product analysis did not confirm the reported fluid leak, as there were no abnormal leaks identified during functional testing.The sound of air escaping the device could be heard during the device stall.Destructive testing was unable to determine the cause of the device stall, and clinical circumstances were unable to be replicated.No other issues were identified during the product analysis.
