During a phlebography procedure, the 5f tempo catheter had difficulty passing through the anatomy and fractured when rotated, being left in two pieces.The fractured part was recovered by the doctor by pulling everything.The separation started near the introducer and the guidewire was inside the catheter.It did not require a secondary intervention.Another catheter was passed and the case could be completed.There was no vessel injury.The patient¿s current condition is normal.There were no abnormalities when the device was removed from the package nor observed during preparation.The device was not resterilized.The device was inserted directly into the sheath introducer.The lesion was not calcified.There was no presence of tortuosity nor angulation.There was no stenosis.The device was not used for chronic total occlusion (total occlusion> 3 months) as the vessel is healthy without any injury or occlusion.There was no resistance encountered when removing the device.The device detached from the manipulation area close to the introducer.The doctor did not slap the broken end.The guidewire used in the procedure was non-cordis.There was no procedural cd available for review.A file with two pictures of a tempo catheter (cath temp0 5 mpa1 (1) 100cm) was received for analysis.The actual device was not returned for analysis.Per visual analysis of the attached pictures, part number and lot number on the inner label were confirmed as part number 451506h0, lot number 17906956.Also, it can be observed that the catheter body shaft was separated near the strain relief area.The body shaft separation area was observed severely twisted damaged.The twisted condition observed seemed as if the body shaft of the unit was forcibly torque manipulated at the strain relief area leading the catheter body shaft to separate.No other anomalies observed.A product history record (phr) review of lot 17906956 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported complaints by the customer as ¿catheter (body/shaft)- tracking difficulty¿ and ¿catheter (body/shaft)- separated - in-patient¿ were confirmed since a separation condition was observed by pictures analysis.However, the cause of the tracking difficulty and the body shaft separation condition could not be conclusively determined based on the pictures¿ visual analysis as the sole information provided.The picture analysis showed evidence that the unit was forcibly torqued/manipulated at the strain relief.Procedural and/or handling factors might have contributed to the reported events.According to the instructions for use (ifu), which is not intended as a mitigation of risk, ¿exercise care when removing guidewires from multiple-curve catheters.To prevent kinking of 5f (1.65 mm) and smaller angiographic catheters; straighten the pigtail catheter tip only with a diagnostic guidewire or, if applicable, with a tip straightener.Do not straighten by hand.Use a guidewire when introducing the catheter through the catheter sheath introducer (csi) and into the left ventricle.Treat all 4f catheters and smaller french sizes with ultimate care.The performance of these products may be impaired if not properly and cautiously handled during unpacking and preparation.Procedures requiring percutaneous catheter introduction should not be attempted by physicians unfamiliar with the possible complications.Complications may occur at any time during or after the procedure.¿ neither the phr review nor the pictures analysis results suggest that the reported events could be related to the manufacturing process of the unit.Therefore, no corrective or preventative actions will be taken at this time.
