Additional Manufacturer Narrative
Three attempts have been made to retrieve the device for evaluation, and it is yet to be received in-house.This complaint investigation was closed based on the device not received, therefore the reported failure mode was not confirmed.In the event that the device is received, the complaint will be reopened and the investigation will be updated with new results.Alleged failure: the blue cassette malfunctioned.Probable root cause: 1.Pressure sensor malfunction/out of calibration 2.Inflow cassette/ tubing pressure sensor membrane failure 3.Mis-inserted cassette/ tubing 4.Motor encoder malfunction/failure (inflow and/or outflow) 5.Roller wheel assembly (inflow and/or outflow) malfunction/failure 6.Roller wheel failure due to peristaltic tubing debris build-up 7.Main board (all) /imx failure (cf) 8.Software malfunction.9.Use errors: user opens pump console/hand control/footswitch user modifies console/hand control/footswitch and/or components user applies force to components when reaching hand inside cassette housing user places foreign substance/material into cassette housing user drops pump/hand control/footswitch or inflicts other exterior damage during handling or transit incorrect scope/cannula hardware combination chosen joint height and pump height difference is greater than 12 inches hand control/footswitch/power/integration cable or usb mis-inserted into console wrong application software uploaded via usb cassette/ tubing partially inserted hand control/footswitch/power/integration cable pulled from cable instead of connector rf/shaver integrated console plugged into the wrong receptacle in the back of the pump hand control is plugged into a pump outside of its intended use pressure settings are incorrect for type or length of procedure, condition of patient, or surgical technique employed flow rate/suction settings are too high or too low for type or length of procedure, condition of patient, or surgical technique employed wash pressure/flow settings set higher than appropriate for type or length of procedure, condition of patient, or surgical technique employed both stopcocks open for a duration of time longer than a few seconds when using a non-inflow/outflow dual-stopcock cannula and suction attached to the second stopcock product used past recommended maintenance or service period without servicing or inspection.Shaver suction lever left closed or rf probe pinch clamp left closed hand control sterilized using incompatible methods footswitch sterilized hand control left in sterilization chamber for longer than necessary to reprocess sterilization instructions in the ifu not followed (placement in tray, # of units, etc.) console cleaned using incompatible methods hand control or footswitch cleaned using incompatible methods abrasive brushes or pads used to clean console, hand control, or footswitch.10.System design 11.Unwanted movement of internal components/wiring 12.Pressure sensor is operated above linear pressure reading range (>450 mmhg for cf) (design) 13.Pump operated at least-favorable environmental conditions for extended period of time 14.Run screen does not adequately indicate overpressure situation 15.Mini wash malfunction (cf) 16.Command not registered from hand control (all), footswitch (cf), (b)(6) (fc, ap) or hermes (ap-hermes ready) 17.Excessive use of wash or turbo 18.Slow reaction time to a quickly closed off shaver outflow at high flow rates 19.Power failure of pump 20.Pressure sensor stuck behind the sensor bracket 21.Electromagnetic interference (emi) from rf communication, hf surgical instruments, esd, or power surge 22.Insufficient cybersecurity (cf).The reported failure mode will be monitored for future reoccurrence.
