(b)(4).Investigation summary: according to the information provided, it was reported that during a knee arthroscopy, when connecting a s50 3mm/50º suction electrode w/ integrated hand piece to the generator it does not function at all (could not coagulate and cut).The device was received and evaluated.Visual inspection revealed signs of activation, cable and connector showed no damage including the pins.Functional test was performed, on ablation and coagulate modes a warning signal appeared as "output shorted," therefore, the device was sent to the supplier for further evaluation.Supplier evaluation result for s50 sm.Dia.Electrode w/integ.Hndpiece-ea: the device was not returned in the original packaging, there are no obvious signs of use, saline residue visible in suction tube, no visible damage to the device shaft, handle, cable or plug.The electrical test was performed with the different parameters as a result the primary capacitance was fail.During functional test, the activation test ablation and coagulation mode were fail.Supplier summary: the investigation established the device function would vary between correct performance, and output short error.From our investigation we were able to confirm the customer reported defect of ¿output shorted¿ during testing of the returned device.Electrodes, which exhibit a similar defect have been further investigated through cap & cap.Both of these capas are now closed.Continuous review of complaints will be performed, and if any adverse trend is noted, a further review of this decision will be undertaken.A manufacturing record evaluation was performed for the finished device (b)(4) number, and no non-conformances were identified.At this point, no further action is warranted.However, depuy synthes mitek will continue to track any related complaints within this device family as a means of monitoring the extent with which this complaint is observed in the field.
