An international customer reported that during a coronary angiogram, the aurous centimeter vessel sizing catheter marking pigtail was inserted into the patient and an attempt was made to perform a run.The catheter was connected to an injector and set on a standard 20 mm at 10 sec run.When the injector commenced to inject, the catheter burst 6 mm from the hub of the catheter outside the patient, emitting iodine and blood.The patient was not affected by this incident.The catheter was exchanged for another one and the procedure continued without further incident.

Investigation - evaluation: a review of the complaint history, device history record, documentation, instructions for use (ifu), quality control data, specifications, and visual inspection of the returned device was conducted during the investigation.A used and damaged aurous centimeter vessel sizing catheter was returned for examination.Measuring from the hub the hole is located at approximately 5.5cm.Measuring from hub toward distal end first kink is at approximately 46.3 cm then measuring from first kink the second one was located approximately 32.6 cm.The wire guide was able to advance through the catheter lumen, but areas of resistance were noted.Three kinks are noted at 46.4 cm and 78.8cm from the proximal end and 1.0cm from the distal end.A 2mm diameter hole is present at 5.6cm from the proximal end.No non-conformities were noted when examining the catheter bonds for cracks, bends, flaps, dents, holes, scratches, pitted or rough surfaces that compromise bond integrity.A review of production and quality documentation did not observe any specific issues with current manufacturing or quality controls that may have contributed to this incident.Review of the device history record of the finished product shows no nonconforming events that would contribute to this failure mode.There were no other reported complaints for this lot number.There is no information regarding the handling of device prior to set up that may have contributed to this device failure.The customer started to use the device when the catheter burst.The catheter was returned with kinks and no kinks were noted by the customer prior to use.There is no information regarding the patient's anatomy that may have contributed to the device failure.Based upon the information provided and the characteristics displayed, it is plausible to suggest that this incident was technique related, product handling related or human anatomy related.Per the quality engineering risk assessment, no further action is required.Monitoring will continue to be performed for similar complaints.However, based on the information provided and the results of our investigation, a definitive root cause could not be determined.
