The complaint device is not being returned, therefore is unavailable for a physical evaluation.A review of the product¿s instructions for use revealed the following warnings; ensure that fluid inflow and outflow is adequate and that the electrode is activated only when surrounded by conductive irrigant solution (e.G., saline or ringer¿s lactate).The use of rf energy with inadequate irrigation may overheat the fluid enough to cause skin burns at or near the access site and may result in damage to the electrode tip assembly.Failure to attach the suction tubing to an adequate suction source may cause thermal injury to the physician or patient.A batch record review has been conducted to determine if there were any internal processing issues which would have contributed to the nature of the product complaint.Our results indicate that this batch of product was processed without incident and therefore there is no internally assignable cause for the reported problem.Further, a review into the depuy synthes mitek complaints system revealed no other complaints of any kind for this lot of (b)(4) devices that were released to distribution.We cannot discern a root cause for the reported failure mode, although a possible root cause is the suction tube of the electrode was not connected as warned against in the product¿s instructions for use.At this point in time, no corrective action is required and 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.
