The product is expected to be returned for analysis; however, it has not yet been received.Upon the return of the product a supplemental report will be sent with the investigation results.The lot number was not provided; therefore, a review of the manufacturing records could not be completed.

One pacing catheter with attached monoject 1.5 cc limited volume syringe, two three-way stopcocks and coset kit was returned for evaluation.A non-edwards contamination shield was located on the catheter body between 30 cm and 90 cm proximal from the catheter tip.A non-edwards introducer was returned detached from the catheter.Customer report of "unable to pace" could not be confirmed during the evaluation.When proximal and distal connectors of the non-edwards contamination shield were at lock position, the catheter body was found to move underneath the contamination shield and a gap was observed between the proximal connector of the contamination shield and the catheter body.Continuity testing was performed on the distal and proximal ventricular circuits and the distal, central and proximal atrial circuits.There were no open, intermittent, or short conditions observed.No visible damage or abnormality to the catheter body, balloon or returned syringe was observed.All through lumens were patent without any leakage or occlusion.The balloon inflated clear and concentric and remained inflated for 5 minutes without leakage.Further evaluation confirmed the report of "diameter of the catheter was small".The outer diameters of the catheter body were measured to be 0.0891", 0.0919" and 0.0915" at 40 cm, 60 cm and 90 cm from the catheter tip, respectively.The outer diameter at 40 cm is out of specification.The specification of the outer diameter of the body tube is 0.092" +0.003"/ -0.002".Balloon inflation test was performed using returned syringe with 1.5 cc air by holding the balloon under water for 5 minutes.Visual examinations were performed under microscope at 10x magnification and with the unaided eye.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.If using a contamination shield, extend the distal end towards the introducer valve.Extend the proximal end of the catheter contamination shield to the desired length, and secure.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.
