One bipolar pacing catheter with attached monoject 1.3 cc limited volume syringe at gate valve was returned for evaluation.Continuity testing found that a short condition occurred around the catheter tip.A cut down of the catheter revealed that lead wires were not insulated inside the catheter tube at 0.8 inch proximal from the proximal electrode.This condition allows contact to be made with both wires and cause a short condition.The balloon inflated clear and concentric and remained inflated for 5 minutes without leakage.No visible damage or abnormality to the catheter body, balloon, windings or returned syringe was observed.Balloon inflation testing was performed using returned syringe with 1.3 cc air by holding the balloon under water.Visual examinations were performed under microscope at 20x magnification and with the unaided eyes.A device history record review was completed and documented that device met all specifications upon distribution.Customer report of pacing issue was confirmed.An investigation has been initiated to consider any potential manufacturing factors that may have contributed to this complaint and implement any necessary corrective actions.Swan-ganz pacing thermodilution (td) catheters serve as diagnostic and therapeutic tools in the management of critically ill patients.There are multiple failure modes that may require the exchange of a pacing catheter.Since proper functioning of the pacing catheter depends on the electrical continuity of its electrodes and internal wires, care should be exercised when handling the catheter.Stretching, kinking, or forceful wiping of the catheter may result in damage.After stable pacing has been confirmed, the proximal end of the catheter should be secured to the insertion site to prevent undue movement that could result in tip dislodgment and loss of capture, or catheter migration.Care should be taken not to kink the catheter body when securing it.In this complaint, it could not be determined if procedural factors or device handling may have contributed to the reported event.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis, and any excursions above the control limits are assessed and documented as part of this monthly review.(b)(4).
