One catheter with attached monoject 1.5 cc limited volume syringe and 2 three-way stopcocks was returned for evaluation.As received the catheter body was cut at 29.5 cm proximal from the catheter tip and blood was observed from the cut section.All lumens were exposed at the cut section.Leadwires and optical fibers were broken off at the cut section.Cross surfaces of the catheter body appeared smooth.Two longitudinal punctures, approximately 3 mm each, were also observed at the distal side of the cut section.The distal lumen, proximal injectate lumen and balloon inflation lumen leaked only from the cut section.After opening the optical module connector, blood was observed inside the connector.No visible damage or inconsistency to the catheter tip, balloon or returned syringe was observed.Visual examination was 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 leakage issue and ¿the catheter was cut¿ 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.Invasive procedures involve some patient risks.Although serious complications are relatively uncommon, the physician is advised, before deciding to insert or use the catheter, to consider the potential benefits in relation to the possible complications.The techniques for insertion, methods of using the catheter to obtain patient data information, and the occurrence of complications is well described in the literature.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.
