One swan-ganz catheter was received at product evaluation laboratory for a full examination.As received, 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 side of the proximal electrode to expose the pacing lead wires.Distal lead wire was found to be broken/detached at the tip.It was also confirmed that the broken/detached distal circuit was continuous to distal connector pin.The balloon inflated clear and concentric with 1.3 cc air and remained inflated for a period of time without leakage.No other visible damage or defect was observed from the balloon, windings, catheter body, and returned syringe.Further investigation was completed by the engineers in the manufacturing site and it could be confirmed that the root cause is likely due to manufacturing.Corrective actions are being in order to eliminate the cause of the non-conformity and prevent recurrence of this type of 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.

As reported, during use, this swan-ganz pacing catheter did not provide signal (medwatch # 38758).The catheter was replaced by another one from a different lot number and same issue occurred (medwatch # 38767).Using a third catheter the issue was solved.There is no allegation of patient injury.The devices were available for evaluation.
