One bipolar pacing catheter with an attached monoject volume limited 1.3 cc syringe at the gate valve was returned for examination.The reported event of a pacing issue was confirmed.Continuity testing confirmed a full open condition in the distal circuit.The proximal circuit was found to be continuous.A cut down of the catheter body was performed just proximal of the proximal electrode to expose the pacing lead wires.The distal lead wire was found to be broken around the solder joint.It was found that the distal circuit was continuous from broken lead wire to distal connector pin.The balloon inflated clear and concentric with 1.3 cc air and remained inflated for 5 minutes without leakage.There was no visible damage or defect observed from the balloon, windings, catheter body, and returned syringe.A review of the manufacturing records indicated that the product met specifications upon release.An investigation has been initiated to consider any potential manufacturing factors that may have contributed to this complaint.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.
